Final answer:
SSL meets its desired requirements by providing data encryption, authentication, and integrity through the use of public key cryptography and digital certificates.
Step-by-step explanation:
SSL (Secure Sockets Layer) is a cryptographic protocol that ensures secure communication over the internet. It meets its desired requirements by providing data encryption, authentication, and integrity.
SSL achieves data encryption by using public key cryptography. When a client initiates a connection to a server, they exchange public keys to establish a secure session. This ensures that any data transmitted between the client and server is encrypted and cannot be easily intercepted by third parties.
In addition to encryption, SSL also provides authentication by verifying the identity of the server. This is achieved through the use of digital certificates, which are issued by trusted certificate authorities. By validating the server's certificate, clients can be assured that they are communicating with the intended server and not an imposter.
