摘要
利用混沌序列的随机性和不可预测性,可将其作为密钥进行数据加密.同时,传统的加密技术所得到的密文容易被攻击者发现,影响了信息的安全性.本文有效地引入信息隐藏方法,提出了基于Logistic混沌序列并将加密与隐藏相结合的算法,防止密文在传送中被监测到,提高了信息的安全性.
Chaotic sequences can be used as cryptographic key to encrypt data, according to randomicity and unpredictability. Meanwhile,it is easy to discover cryptograph by traditional encryption technology by attacker and it affects security of information. Method of hiding information is introduced effectively in this paper,and an encryption and hiding algorithm based on Logistic chaotic sequences is put forward. This algorithm can avoid transmissive cryptograph monitored by attacker, and improve security Of information.
