Three part hybrid encryption schema

Abstract

Hybrid encryption schemes are consist of two parts. First part for encryting the text with symmetric algorithm called DEM (Data Encryption Mechanism) and the second one is for encrypting the symmetric algorithm key with asymmetric algorithm called KEM (Key Encryption Mechanism). If we think to expand the KEM packet with e-sign, message digest and extra security data for validation and authentication, how will be the encryption of KEM packet and also the performance KEM mechanism. Our study try to answer that question and also offer a new hybrid encryption mechanism for information security.
