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 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...
Hardware efficient stream ciphers and hash functions are widely used in cryptographic applications. The one-wayness and low hardware complexity of hash function make it a good candidate for authentication operation of crypto-systems. On the other hand, stream ciphers are being widely used in the domain of cryptology. Generally, these stream ciphers use static key stream for the crypto process. In...
