%X Nowadays encryption and spread spectrum communication based on chaos is a hot research topic.Yet the limited precision of computer makes chaotic sequences degenerate to periodic ones and haven't enough key space.In the paper we have designed a stream cipher based on chaos and matrix transform.six two-dimensional chaotic sequences are used to control three kinds of matrix transform and the scanning of a sort of special(0,1)-matrices.The result sequence satisfies the requests for stream cipher.The simulation also implies it has good statistic characters.
