基于云计算的混合混沌加密算法研究

Research on hybrid chaotic encryption algorithm based on cloud computing

针对云平台环境下数据安全及保密问题,基于MapReduce分布式框架下,综合4种混沌映射系统的优点,提出一种面向云计算的混合混沌加密方法。利用4种混沌映射产生的混沌序列作为密钥,多次使用从混沌系统迭代产生的多重密钥对明文进行加密操作。实验结果证明,该算法的执行效率高,密钥空间足够大,能够有效抵抗暴力破解密钥的攻击。

Aiming at the problem of data security and confidentiality in the cloud platform environment, based on the MapReduce distributed framework, combining the advantages of four chaotic mapping systems, a hybrid chaotic encryption method for cloud com-puting is proposed. Using the chaotic sequence generated by four chaotic maps as the key, the plaintext is encrypted by using the multiple key generated from the iteration of chaotic system for many times. The experimental results show that the algorithm is effi-cient and the key space is large enough to effectively resist the attack of brute force key cracking.
