摘要：In cloud ensures the data security of data access control. The challenges in cloud storage system are dataaccess control, data outsourcing and the unreliable cloud server. Ciphertext-Policy based on attributesEncryption (CPABE)is viewed as a standout amongst the most appropriate information get to control benefits in distributed storage, asit gives information proprietors have more straightforward control over access approaches.Furthermore, it is extremelyhard to apply the ways out information straightforwardly to exist CP-ABE programs get to control for distributedstorage frameworks due to issue of trait repudiation. In that, design the multi authority scheme for revocable dataaccess control system in cloud storage system, where more authority exists contain and each authority can left attributesindependently. Purpose a reparable multi-authority CP-ABE and apply it as the underlying methods to design the dataaccess control schema.The method of withdrawing attributes you can get both forward and backward safety effectively.The results of the analysis and the simulation show that our information is proposed the access control scheme is securein the random oracle model and is more efficient than existing.
