Secure storage and accessing the data in cloud using optimized homomorphic encryption

Abstract

Different efforts have been undertaken to customizing a security and privacy concern in cloud data access. Therefore, the security measures are reliable and the data access was verified as the major problem in the cloud environment. To overcome this problem, we proposed an efficient data access control using optimized homomorphic encryption (HE). Because users outsource their sensitive information to cloud providers, data security and access control is one of the most difficult ongoing cloud computing research projects. Existing solutions that rely on cryptographic technologies to address these security issues result in significant complexity for both data and cloud service providers. The experimental results show that the key generation is 7.6% decreased by HE and 14.14% less than the proposed method. The encryption time is 11.34% less than the optimized HE and 23.28% decreased by ECC. The decryption time is 13.18% and 24.07% when compared with HE and ECC respectively.
