Abstract

K2 is a new type of word oriented stream cipher that has dynamic feedback control. Existing research has shown that K2 v2.0 is a high performance stream cipher in software implementations and can be used in several applications. However, no evaluation results for its performance in hardware implementations have been published. In this paper, we presented two hardware implementations of K2 v2.0: a high speed implementation and a compact implementation. We then show the evaluation results on FPGA implementation simulations. The implementations of K2 demonstrated high efficiency compared with other stream ciphers, with K2 being 4-10 times higher than AES implementations. We think that the FPGA implementation of K2 is suitable for applications using high speed encryption/decryption.
