Abstract :
Cache-timing attacks on the Advanced Encryption Standard block cipher provoked a mass reaction against use of s-boxes in cipher design. This reduced diversity in design strategies. We show that s-boxes can be safely used in stream ciphers, provided that consideration is given to minimizing information leakage.
