WebSymmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). WebA session key is any symmetric cryptographic key used to encrypt one communication session only. In other words, it's a temporary key that is only used once, during one stretch of time, for encrypting and decrypting datasent between two parties; future conversations between the two would be encrypted with different session keys.

WebTo communicate using symmetric key cryptography each pair of people must share a key. This leads to the N (N-1)/2 equation. However, most systems will assume your keys are uni-directional so each sender has a unique key for each receiver, this doubles the number of keys to N (N-1).

WebSession keys are sometimes called symmetric keys because the same key is used for both encryption and decryption. The session key is used for only one session. It is then discarded, and a new key is randomly generated for the next session.
