| 2. | In this dissertation , a novel method designing s - box is proposed , which combined chaotic cryptography and computing intelligence . in addition , the cryptographic properties such as the bijective property , the strict avalanche criterion , the nonlinearity , the output bits independence criterion and the equiprobable input / output xor 本论文中,不仅提出了运用混沌系统构造s盒的新方法,而且还首次把混沌密码学和计算智能算法相结合,提出了一种新的s盒的设计方法。 |
