In cryptography technology,random sequence is very important,and the randomness test of sequence is always an important subject in information security.For the shortcomings of current randomness test system,a randomness test system is researched and de-signed in Visual C++.NET.According to the difference between stream cipher and block cipher,the system tests separately.In stream cipher,a new kind of partition and organization method of test sequence is given,while in block cipher,three data mode are designed to build sequence that will be tested.The system is tested strictly,and it is proved that the system can test randomness of stream cipher,block cipher and random number generator quickly and accurately.
