SSL and TLS.

a) Explain the terms SSL and TLS.
b) Explain the following terms used in TLS.
i) Record protocol
ii) Handshake protocol
iii) Session caching
c) Give two differences between SSL and TLS.

Expert Solution

SSL and TLS are cryptographic protocols that authenticate data transfer between servers, systems, applications and users. For example, a cryptographic protocol encrypts the data that is exchanged between a web server and a user.Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used.Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic security protocols. They are used to make sure that network communication is secure. Their main goals are to provide data integrity and communication privacy. ... The parties agree on which algorithm to use during initial communication.

TLS is a cryptographic protocol that provides end-to-end security of data sent between applications over the Internet. It is mostly familiar to users through its use in secure web browsing, and in particular the padlock icon that appears in web browsers when a secure session is established.

The record protocol is the secure communications provider. Its purpose is to encrypt, and authenticate packets. The record layer functions can be called at any time after the handshake process is finished, when there is need to receive or send data.

The TLS Handshake Protocol is used to authenticate the participants of the communication and negotiate an encryption algorithm. This allows the client and server to agree upon an encryption method and prove who they are using cryptographic keys before any data is sent between them.

A session cache allows a server to store session information from multiple clients. WebSEAL uses two types of session caches to accommodate both HTTPS and HTTP session state information between clients and WebSEAL: WebSEAL session cache.

SSL is a cryptographic protocol that uses explicit connections to establish secure communication between web server and client. TLS is also a cryptographic protocol that provides secure communication between web server and client via implicit connections.

What are the difference and similarities between TLS and SSL?

SSL refers to Secure Sockets Layer whereas TLS refers to Transport Layer Security. ... SSL and TLS are cryptographic protocols that authenticate data transfer between servers, systems, applications and users. For example, a cryptographic protocol encrypts the data that is exchanged between a web server and a user.

TLS is frequently and incorrectly described as a total security solution for digital business via credit card transaction. What is the implication of this statement in relation to SSL adding security to Web based sales transactions (via credit card)? Your answer should clearly explain where SSL provides security, and where it does not (in relation to the sales transaction).
