In this paper, a novel pseudo-random sequence generator (PRSG) based on spatial chaos system is proposed. The statistical tests and correlation analysis on the proposed PRSG are performed by the well-known Federal Information Processing Standards FIPS140-1, and the experimental results show that the image encryption based on spatial chaos ergodic matrix has good random statistical characteristics, large key space and great sensitivity of the sequence.
