Big Data Encryption Storage System Design Under Cloud Environment

Abstract

Contraposing to the security of cloud storage service network and data sharing characteristics, a ciphertext access control mechanism based on CP-ABE algorithm is proposed. The access control mechanism is studied from two aspects: access control and access control architecture. The corresponding data structure of security algorithm is provided, and its simulation and performance analysis are performed. The security mechanism ensures the security of data in cloud storage system under open environment and reduces the complexity of privilege management through attribute management, under the premise that service providers are not credible. The cloud storage system designed and implemented in this paper achieves the original design object and performs well in all aspects, which is of great importance to the safe and effective storage of user's information and data in the era of large data.
