Sarbajit Manna, Saurabh Dutta . A Stream Cipher based Bit-Level Symmetric Key Cryptographic Technique using Chen Prime Number. International Journal of Computer Applications. 107, 12 ( December 2014), 18-22. DOI=10.5120/18802-0328
Abstract
In this paper, a stream cipher based symmetric key cryptographic technique based on Chen prime number has been proposed. The proposed technique is suitable for encryption and decryption of a large number of files of almost any type. A symmetric key is formed by the sender directly from the plain text using Chen prime number. Then a symmetric key value is derived from the symmetric key which is used to form the cipher text. The symmetric key is sent to the receiver by the sender. The symmetric key value is derived by the receiver from the symmetric key which is used for decryption. To enhance security, focus is to secure the symmetric key value rather than the symmetric key.
