Network and Internet Security - evidence ExampleOn the other hand, the single describe encryption only uses a single mystical key for both encryption and decryption of messages. A hybrid of the two that is single key and macrocosm key encryption is what the modern encryption model entails to help establish reliable secure sessions. jibe to De & Yung (2006, 127), session keys help enhance security of a system in cases where two parties have an encrypted connections to terzetto party. By use of these session keys, the third party can deliver keys the other two parties on the encrypted links. posing keys are established by use of Diffie-Hellman key exchange which enables the secret exchange of keys amongst two users on a communication channel by the use of exchange algorithms. This way of key generation does not required the presence of a central documentation server or each key distribution center. These two users maintain a secured encrypted message through a partial touch o f information. Some entropy is privately stored while some is publicly given for the other party to use. apply exchange algorithms, the two parties can use the publicly aired data to encrypt hidden messages from senders on a crowded communication channel (De & Yung 2006, 127). User 1 computes the key using the public data given by user 2 and viceviser. Both calculations will eventually yield similar results indicating a common interpretation.Kerberos V4 uses session keys to help maintain a secured communication protocol (Bao, Deng & Zhou 2004, 30). Kerberos v4 are utile in verifying users at work places who would wish to access services within a network. Session keys use in Kerberos would restrict access only to identified and authorized users and would accurately authenticate requests for uses. These authentication procedures make the use of session keys become very relevant in Kerberos. It will be nigh impossible for another side user to communicate with the server since the g iven session key is
