Abstract

Abstract: To protect the confidentiality and integrity of data stored in cloud, we propose a new data encryption and PDP verification algorithm based on multi chaos sequences, which can encrypt cloud storage data and support PDP verification at the same time. By the algorithm, users can produce multi chaos sequences by a key composed of a pure decimal and an integer. Using those sequences, they can complete cloud storage data encryption and PDP verification code embedding by running the algorithm once. Because it hides the places and values of embedded PDP verification code by chaos sequences, the algorithm supports unlimited times PDP verification request. Experiments show that the algorithm has strong ability of data security protection and outstanding efficiency of data encryption and decryption.
