Currently, the global standard for secure network interactions, TLS, was originally developed as an improvement over the then standard SSL protocol back in 1999. While it was designed to be an upgrade to the existing SSL 3.0 protocol, there were sufficient differences in the design of each protocol to make interoperability between the two schemes infeasible. Instead, the authors released it as the first version of a newer, more secure protocol.
TLS as the new standard
A minor evolution from SSL
When it was introduced, TLS certainly represented an improvement over SSL 3.0. However, the major distinctions were in the header design for the packets exchanged during the handshake phase of connection establishment. The underlying...
