Intrusion Prevention Method to Secure Network Sessions

Instead of data encryption and decryption that is randomly generated to ensure the security of a communications session between a user and another computer or between two computers. Session security, because the session key is used for both encryption and decryption. A session key may be derived from a hash value, using the CryptSessionKey function (this method is called a session-key derivation scheme). Throughout each session, the key is transmitted along with each session and is encrypted with the recipient's key. Much of their security relies upon the brevity of their use, session keys are changed frequently. A different session key may be used for each session.
