Abstract

In this paper, a new design for dynamic key based stream cipher is proposed for the hardware cryptographic applications such as data transmission and information security. Unlike the static key based existing stream ciphers, the key stream is usually fixed which is either a public key or a private hardware key. However, in this proposed design, we have constructed the dynamic key stream the novelty of this proposed stream cipher is based on dynamic key, generated by Toeplitz hash function which is used as a key for RC4 stream cipher. Further, this key is used to generate the dynamic hardware key for the cryptographic processor. In an effort to increase the speed via pipelining it is proposed to Toeplitz Hash Function algorithm.
