SSL/TLS provides protocol security in several ways:
1. Encryption: SSL/TLS provides encryption of data which is transmitted between the two parties, i.e., the client and the server. This means that even if an attacker intercepts the communication, they will not be able to read the data. The encryption provided by SSL/TLS uses symmetric key cryptography which ensures the security of the data being transmitted.
1. Authentication: SSL/TLS provides authentication of both the client and the server. This ensures that both parties are who they claim to be, and that the communication is only occurring between authorized parties. SSL/TLS does this through the use of digital certificates, which are issued by trusted third parties, known as Certificate Authorities (CAs).
1. Integrity: SSL/TLS provides integrity of the data transmitted between the two parties, by ensuring that the data has not been tampered with during transmission. This is done through the use of digital signatures, which provide assurance that the data has not been altered.
1. Non-Repudiation: SSL/TLS provides non-repudiation, which means that neither party can deny that they have sent or received a message. This is achieved through the use of digital signatures, which are legally binding and can be used as evidence in court.
Overall, SSL/TLS provides a secure communication protocol by providing encryption, authentication, integrity, and non-repudiation.
