Secret Variant Session Key Based Symmetric Cryptography - Tapa blanda

Sinopsis

Whenever any data exchange transpires through internet, the basic thing that comes to mind is secure communication. The successful and protected communication of any private data is the primary concern of almost all fields. Each and every one desire secured environment to communicate with the authentic beneficiary more willingly than an adversary. Session key based encryption technique helps to meet that precise goal where exchange of key is mandatory before every communication. General explanation is, the new session key be the function of the previous both key and data. So, after every session one needs to extract the next session key and to remember till the next session. In this Book, we have proposed an encryption technique using secret variant session key which is actually constructed from the original user key and the present secret data to be sent by the sender. But our proposed scheme does not require extracting and remembering of session key to construct next session key although the session key changes in every session. We have also introduced two layers of encryption technique which is more robust to defend against any crypto-attack.
