Integration of CFEA-compression technique into asymmetric key cryptosystems

In order to provide good level of security,modern cryptosystems need to implement large numbers and complicated mathematical operations. as a consequence,efficiency becomes a new major issue in cryptography. by using proper parameters,some of established asymmetric cryptosystems are believed to be able to provide a good level of security. since that,aim to develop a mechanism to accelerate encryption and decryption processes of asymmetric cryptosystem without altering their original encryption and decryption algorithms become a big consideration. the aim of this paper is to propose the integration of a compression technique that named as cfea-compression technique into some established asymmetric key cryptosystem such as rsa,el-gamal and elliptic curve cryptosystems. cfea-technique is a combination of continued fraction and euclidean algorithm (cfea) which is able to reduce the number of plaintext and ciphertext prior the encryption and decryption procedures. © 2016 penerbit utm press. all rights reserved
