RC4 was designed in 1987 when 8-bit and 16-bit processors were commercially available. Today, most processors use 32-bit or 64bit words but using original RC4 with 32/64 bits is in...

Abstract. Given (deterministic) ciphers E and E that can encipher messages of l and n bits, respectively, we construct a cipher E∗ = XLS[E, E] that can encipher messages of l + s...

This paper proposes a blockcipher mode of operation, HCTR, which is a length-preserving encryption mode. HCTR turns an n-bit blockcipher into a tweakable blockcipher that supports ...
