摘要: In this study, the authors use a non-symmetric partition to generate N-phase pseudorandom sequences using logistic maps. The theoretical analysis shows that sequence is with uniform distribution, as well independent and identically distributed. Numerical experiments show these have high complexity are good randomness. A fast algorithm its time be O(M) proposed sequences. Furthermore, they propose new image encryption based on sequence, which combined both shuffling substitution algorithms. Several security tests carried out demonstrate authors’ level, can resist various attacks, competitive some other recently
