Abstract
This paper firstly investigated the basic operations in some usual cipher algorithms,then introduced researches in cipher instruction set extensions.In the end,due to the fact that cipher systems should support multiple cipher algorithms,the direction of this field in the future was pointed out,that was,the extended instructions should be designed with the characteristic of generality and general cipher processor was the final aim of cipher instruction set extensions.
