TLS (Transport Layer Security) and WTLS (Wireless Transport Layer Security)

Although TLS exchanges follow the same schemes as SSL, the two protocols differ on several points. The main differences concern the following items:

• The instant at which the encryption of the sent data starts • The available cipher suites • The method of computation of the MasterSecret and derivation of the keys • The number of Alert messages • The reaction to Record blocks of unknown types

Let us have a closer look at these differences.
