This document discusses certificate authorities (CAs) and provides an example scenario for securing a web server using a CA. It defines a CA as an entity that issues digital certificates for use by other parties in public key infrastructure schemes. There are commercial CAs, as well as CAs run by institutions and governments. The document then describes the process a CA goes through to issue a certificate and how users can verify certificates. It provides a list of common CAs. Finally, it presents a scenario where a web server obtains a server certificate from a CA to secure its SSL port, and clients can obtain client certificates from the CA's website to access the secure site.
Introduction to Public Key InfrastructureTheo Gravity
Adonis Fung and I worked on a project where we defined and built PKI (Public Key Infrastructure) for our local development and deployed environments. I gave a talk to our engineers on how PKI works, covering encryption, signing, trust stores, and how the HTTPS handshake works.
Digital signatures use asymmetric cryptography to authenticate digital messages. They allow a recipient to verify the identity of the sender and confirm the message has not been altered. A digital signature scheme involves key generation, signing, and verification algorithms. Digital signatures provide authentication, integrity, and non-repudiation and are commonly used for software distribution, financial transactions, and other cases requiring detection of forgery or tampering. They offer advantages over traditional ink signatures like inability to forge or erase the signature.

Advanced cryptography and implementationAkash Jadhav
The document discusses a technical presentation on advanced cryptography and its implementation. It provides an overview of cryptography, including its history and basic concepts such as encryption, decryption, and cryptanalysis. Examples of cryptography applications discussed include ATM cards, credit cards, e-mail, and lottery tickets.
Digital signatures provide authenticity, integrity and non-repudiation to electronic documents by using public key infrastructure. Under PKI, each individual has a public/private key pair, and certification authorities verify and certify individuals' public keys. Digital signatures are generated by encrypting a document hash with an individual's private key and can be verified by decrypting with the corresponding public key.
Cryptography is the practice and study of securing communication through techniques like encryption. It has evolved through manual, mechanical, and modern eras using computers. Cryptography aims to achieve goals like authentication, confidentiality, integrity, and non-repudiation. Common attacks include brute force, chosen plaintext, and differential power analysis. Symmetric cryptography uses a shared key while asymmetric uses public/private key pairs. Digital signatures and watermarks can authenticate documents. DRM and watermarks control digital content distribution.
Digital signatures provide authentication and integrity for electronic documents and transactions. They use public key cryptography where a document is encrypted with the sender's private key and decrypted by the recipient's public key. A digital certificate issued by a certificate authority binds the signer's identity to their public key and is verified using the CA's digital signature. Common uses of digital signatures include software updates, financial transactions, and legally binding documents.
This document discusses the history and uses of cryptography and digital certificates. It provides an overview of how public key infrastructure (PKI) uses public and private key pairs to securely exchange information over networks. A certification authority (CA) is responsible for issuing digital certificates which contain a public key and verify identity. PKI and digital certificates are used for applications like encryption, digital signatures, authentication, and secure communication protocols.
Digital signatures provide authentication of digital documents by using asymmetric cryptography algorithms like RSA. Digital signatures demonstrate that a message was created by a known sender and was not altered in transit. They are commonly used for software distribution, financial transactions, and anywhere unaltered authentication is important. Digital signatures work by using public and private keys to encrypt a hash of the message, validating the source and integrity of the signed document.
Public key encryption uses key pairs (public and private keys) to encrypt and decrypt messages. Digital signatures authenticate messages by encrypting a message digest with the private key. To send an encrypted and signed message:
1. The sender calculates a message digest and signs it with their private key.
2. A symmetric key is generated and used to encrypt the message and signature.
3. The symmetric key is encrypted with the recipient's public key and sent with the encrypted message and signature. The recipient decrypts the symmetric key to decrypt and verify the message.
This document discusses digital signatures and how they provide security services like secrecy, authentication, non-repudiation and integrity. It explains that digital signatures use asymmetric cryptography with a private key for signing and a public key for verification. The digital signature is created by hashing the message and signing it with the private key. When received, the message hash is verified using the public key to authenticate that the signature was created by the private key owner and that the message has not been altered. Digital signatures thus authenticate messages and ensure non-repudiation by binding the signer to the message in a way that can be verified.
This document provides an overview of cryptography concepts including symmetric and asymmetric key algorithms, cryptographic hashes, and tools for cryptanalysis. It defines common terminology like plaintext, ciphertext, encryption, and decryption. Symmetric algorithms discussed include the Vernam cipher, A5/1, DES, AES, and RC4. Asymmetric algorithms covered are RSA and Diffie-Hellman key exchange. Cryptographic hashes like MD5 and SHA-1 are also summarized along with resources for cryptanalysis.
The document discusses digital signatures, including how they work, their history, applications, and legal status in India. A digital signature uses public and private keys to authenticate a message sender's identity and verify that the message was not altered. It explains how digital signature certificates are issued by certified authorities and associate an individual's identity with their public and private keys. The document also addresses frequently asked questions about digital signatures, such as how they provide security, who issues them, how long they are valid for, and their legal standing.
A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (authentication and non-repudiation) and that the message was not altered in transit (integrity). Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering.
Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures. In some countries, including the United States, India, and members of the European Union, electronic signatures have legal significance.

Today in modern era of internet we share some sensitive data to information transmission. but need to ensure security. So we focus on Cryptography modern technique for secure transmission of information over network.
Easy for the signer to sign a message
There is no point in having a digital signature scheme that involves the signer needing to use slow and complex operations to compute a digital signature.
Easy for anyone to verify a message
Similarly we would like the verification of a digital signature to be as efficient as possible.
Hard for anyone to forge a digital signature
It should be practically impossible for anyone who is not the legitimate signer to compute a digital signature on a message that appears to be valid. By “appears to be valid” we mean that anyone who attempts to verify the digital signature is led to believe that they have just successfully verified a valid digital signature on a message.
A certifying authority issues digital certificates that certify ownership of a public key by a named subject. This allows secure connections by having clients use the CA certificate to authenticate the CA signature on a server certificate before connecting. Commercial CAs charge fees to issue certificates so that their certificate is trusted by browsers, improving security out of the box for users connecting to certified servers. Non-profit CAs also issue free digital certificates. Large organizations may have their own public key infrastructure with internal CAs, while any site using self-signed certificates acts as its own CA.

Solution
A Root SSL certificate could be a certificate issued by a trusty certificate authority (CA).In the
SSL system, anyone will generate a language key and sign a replacement certificate therewith
signature. However, that certificate isn\'t thought-about valid unless it\'s been directly or
indirectly signed by a trusty CA.A trusty certificate authority is Associate in Nursing entity that
has been entitled to verify that somebody is effectively World Health Organization it declares to
be. so as for this model to figure, all the participants on the sport should agree on a group of CA
that they trust. All operational systems and most of net browsers ship with a group of trusty
CAs.The SSL system is predicated on a model of trust relationship, conjointly known as “chain
of trust”. once a tool validates a certificate, it compares the certificate establishment with the list
of trusty CAs. If a match isn\'t found, the shopper can then check to check if the certificate of the
supplying CA was issued by a trusty CA, so on till the tip of the certificate chain. the highest of
the chain, the basis certificate, should be issued by a trusty Certificate Authority.
Self-signed certificates or certificates issued by a non-public CAs aren\'t appropriate to be used
with the overall public.A certificate serves two essential purpose distribute the public key and
verifying the individuality of the server so guests know they aren’t sending their information to
the wrong person. It can only properly verify the identity of the server when it is signed by a
trusted third party because any attacker can create a self-signed certificate and launch a man-in-
the-middle attack. If a user just accept a self-signed certificate, an attacker could drop on all the
traffic or try to set up an imitation server to phish additional information out of the user. Because
of this, you will approximately on no account want to use a self signe.

1. The implicit grant type is used for mobile apps and web applications where client secret confidentiality cannot be guaranteed. It returns the access token directly to the client instead of an authorization code.
2. The user is redirected to the authorization server to log in and authorize access. If approved, the access token is encoded in the redirect URI returned to the client.
3. The client extracts the token and can use it to access protected resources, without having to make a separate request to exchange an authorization code for a token. However, the token is exposed in the redirect URI, so it has a short lifetime.

Explain the role of the certificate authority and registration autho.pdfashokarians
Explain the role of the certificate authority and registration authority in Public Key
Infrastructure.
Solution
A certificate authority (CA) that stores, issues and signs the digital certificates. It acts as the
root of trust and provides services that authenticate the identity of individuals, computers and
other entities.A CA issues digital certificates to entities and individuals after verifying their
identity. It signs these certificates using its private key; its public key is made available to all
interested parties in a self-signed CA certificate. CAs use this trusted root certificate to create a
\"chain of trust\" -- many root certificates are embedded in Web browsers so they have built-in
trust of those CAs. A registration authority(RA) which verifies the identity of entities requesting
their digital certificates to be stored at the CA. It is an authority in a network that verifies user
requests for a digital certificate and tells the certificate authority (CA) to issue it. RAs are part of
a public key infrastructure (PKI), a networked system that enables companies and users to
exchange information and money safely and securely. The digital certificate contains a public
key that is used to encrypt and decrypt messages and digital signatures..
Digital certificates allow for secure electronic communication and transactions over the internet. There are three main types of digital certificates: secure socket layer (SSL) certificates, code signing certificates, and client certificates. SSL certificates secure credit card transactions and login information on a website using encryption. Code signing certificates digitally sign software to authenticate that it comes from the claimed publisher. Client certificates contain information about a client that allows a server to identify and authenticate the client during a secure session. Digital certificates are issued by certificate authorities to facilitate secure e-commerce and internet communication using public key infrastructure (PKI) technology.
The document discusses various authentication patterns for securing web services, including direct authentication where the client presents credentials directly to the service, and brokered authentication where a trusted third party broker issues a security token. It analyzes scenarios for public web services, intranet services, and those between businesses, summarizing the authentication approaches best suited to each scenario.
SDWAN Concept - Certificate and keys Roles in Controllers and vEdge Router Au...Farooq Khan
WAN edge routers and controllers in a Cisco SD-WAN solution mutually authenticate using an authorized list model and certificates. Controllers and routers verify each other's identities by validating certificates signed by a certificate authority against the locally stored root certificate, comparing organizational names, and checking serial numbers against the authorized list. This establishes a secure DTLS/TLS tunnel between authenticated devices for network traffic forwarding.
InfoSecurity Europe 2015 - Identities Exposed by David JohanssonDavid Johansson
Client certificates can expose users' private identity information if not implemented securely. Browsers may send certificates without user consent, validating only after exposure. Spoofed servers can steal identities by exploiting protocol issues like implicit key validation and certificates sent in plaintext. System designers should limit included identity details, raise user awareness, and prefer TLS versions protecting privacy like 1.3.

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

Certification authority
1. Certificate authority
In cryptography, a certificate authority or certification authority (CA) is an entity which issues digital certificates for use
by other parties. It is an example of a trusted third party. CAs are characteristic of many public key infrastructure (PKI)
schemes.
There are many commercial CAs that charge for their services. Institutions and governments may have their own CAs, and
there are free CAs.
Issuing a certificate
A CA will issue a public key certificate which states that the CA attests that the public key contained in the certificate
belongs to the person, organization, server, or other entity noted in the certificate. A CA's obligation in such schemes is to
verify an applicant's credentials, so that users (relying parties) can trust the information in the CA's certificates. The usual
idea is that if the user trusts the CA and can verify the CA's signature, then they can also verify that a certain public key does
indeed belong to whomever is identified in the certificate.
List of certificate authorities
Here is a list of some common certificate authorities (CA). For a CA to be of any use, the client must trust the CA. In case of
a browser visiting a web site with a certificate, the CA for that certificate should ideally be known by the browser. If not, the
user will be asked whether to trust the CA. Some of the CAs below claim to be known by 99% of all browsers.[1]
• VeriSign
• Thawte
• Entrust
• QuoVadis
• GoDaddy
• Cacert (free CA)
• EJBCA
Scenario for Securing the Web Server using CA( Certification Authority)
Socket Address
The combination of the IP Address and Port Number is called as Socket Address.
2. Steps to Secure the IIS using Certification Authority:
1.Create one web site in IIS
Web Server IP 100.0.0.2
M 255.0.0.0
2.Install the Certification Authority
Certification Authority Server IP 100.0.0.1
M 255.0.0.0
3.Seuring the Web Server using ( Server Certificate )
a. Obtain Web Server Certificate from Web Server
Steps to obtain the Server Certificate :
1.Go to Properties of the Web Server Web site
2. Select the Directory Security -> Server Certificate -> Next -> Create a new Certificate
->Send the Request Immedate to the online Certification Authority -> Next ……….
3.Go to Properties of the Web Server Web site -> Genral -> SSL Port 1234 -> OK
4.Try to access the web site at the client side. ( The Response is : The must be viewed over a secure Channel )
Steps to download the Client Certificate from the Certification Authority
Client can use the Certification Authority Web site to download the Client Certificate
Steps to download :
1. mmc -> console-> add/Remove snap-in -> add -> Certificates -> My user Account -> OK
SSL ( Secure Socket Layer )
pronounced as separate letters) Short for Secure Sockets Layer, a protocol developed by Netscape for transmitting private
documents via the Internet. SSL uses a cryptographic system that uses two keys to encrypt data − a public key known to
everyone and a private or secret key known only to the recipient of the message. Both Netscape Navigator and Internet
Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card
numbers.By convention, URLs that require an SSL connection start with https.
