Abstract

Jump registers have been proposed as building blocks for stream ciphers. In this paper, a construction based on these principles is described. The proposed encryption primitive is a synchronous stream cipher accommodating a key of 128 bits and an IV of 64 up to 162 bits, or an 80-bit key and 32 to 108 bit IV. The stream cipher is particularly designed to resist side-channel attacks and can be efficiently implemented in hardware for a wide range of target processes and platforms.
