|
TLS is a successor of SSL.
|
|
|
TLS uses two layers of protocols.
|
|
|
SSL requires additional computer time when compared to TLS.
|
|
|
TLS implements authentication, encryption and data integrity.
|
Detailed explanation-1: -SSL/TLS provides integrity but no confidentiality of the communications between a client and a server.
Detailed explanation-2: -Hence the correct answer is the client sends “client hello” with a set of encryption and hashing algorithms available to it and the server responds with its choice of the encryption and hashing algorithms from those sent by the server.
Detailed explanation-3: -A primary difference between SSL and TLS is message authentication. SSL uses message authentication codes (MACs) to ensure messages are not tampered with during transmission. TLS does not use MACs for protection but instead relies on other means, such as encryption, to prevent tampering.
Detailed explanation-4: -Expert Answer TLS is Transport Layer Security. Erlier SSL was used for the secure connection between server and client. Later on, with arising vulnereblity in the SSL, TLS came into existance.
