COMPUTER NETWORKING

Detailed explanation-1: -A session key is an encryption and decryption key that is randomly generated to ensure the security of a communications session between a user and another computer or between two computers. Session keys are sometimes called symmetric keys because the same key is used for both encryption and decryption.

Detailed explanation-2: -Public-key encryption, which creates a public-key encrypted session key packet using the public key of the recipient to encrypt the data; only the recipient can decrypt this data with the corresponding private key.

Detailed explanation-3: -Public key cryptography, also known as asymmetric cryptography, uses two separate keys instead of one shared one: a public key and a private key. Public key cryptography is an important technology for Internet security.

Detailed explanation-4: -In cryptography, Master/Session is a key management scheme in which a pre-shared Key Encrypting Key (called the “Master” key) is used to encrypt a randomly generated and insecurely communicated Working Key (called the “Session” key). The Working Key is then used for encrypting the data to be exchanged.
