Abstract :
A word-oriented stream cipher named TAIYI for confidentiality and integrity algorithms of 3G is presented, together with preliminary security analysis and implementation results. The proposal is a clock-controlled filter generator using sigma-LFSR as source part and inverse function to generate key stream. The design is based on simple and well-studied concepts, and it can be easily implemented in hardware, especially for restricted hardware environments such as 3G mobile communications and services.
