TLS vs. SSL
Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols that encrypts data transfer between a client (browser) and a server (web server, file servers etc) across an insecure channel or network. Both the TLS and SSL protocols work on three data security principles: Availability, Integrity and Confidentiality. Associating these three elements provides a comprehensive view of online data transaction security. However, both protocols technically differ from each other.
TLS (Transport Layer Security)
The TLS protocol was designed in the year 1999 to establish a standard encryption mechanism to facilitate privacy while communicating over unsecure networks. Its main objective is to avoid wiretapping or rather eavesdropping, unauthorized manipulation of data and also message forgery.TLS is tailored to deliver a cryptographic security kind of system to maintain privacy of information being transmitted between the client and the server. It consists of two layers:
– Handshake protocol-Authorizes and authenticates communication between the client and the server.It ensures that both parties agree on a set of cryptographic keys before transmission of data between them.
– TLS Record Protocol-Concerned with ensuring privacy of the connection between the server and the client by utilizing a set of cryptographic keys. Connections of such nature can be encrypted through hashing algorithms.
