Zero-correlation Linear Cryptanalysis of SAFER Block Cipher Family Using the Undisturbed Bits

Abstract

SAFER is a family of block ciphers, which is comprised of SAFER K, SAFER SK, SAFER+ and SAFER++. SAFER SK was proposed to strengthen the key schedule of SAFER K. SAFER+ was designed as an AES candidate and SAFER++ was among the cryptographic primitives selected for the second phase of the NESSIE project. This paper presented the first zero-correlation… (More)
