High-speed stream cipher
Hong-Sain Ooi · 2004
We propose a new stream cipher suitable for high-speed network applications, called HSSC (high-speed stream cipher). HSSC uses simple structure to allow detailed analysis and high software performance. The software implementation using C is about 2.07 cycles per byte on a Pentium II 450MHz platform. HSSC uses twelve 32-bit variables as internal states, four predefined constants, four key-derived constants and a set of rules to combine the internal states into 128-bit output per round.
