Research on hybrid chaotic encryption algorithm based on cloud computing

Abstract： 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 computing 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 efficient and the key space is large enough to effectively resist the attack of brute force key cracking.
