An Efficient Security Mechanism for Cloud Data Using Elliptic Curve Digital Signature Algorithm with Wake–Sleep

Abstract

As cloud computing ends up common, increasingly touchier data are being concentrated into the cloud. For the refuge of information protection, delicate information more often than need not to be mixed before redistributing, which makes viable information use a difficult assignment. The proposed structure gives the protection to information in order. In this structure, cloud service provider (CSP) chooses the best host utilizing wake–sleep algorithm. After server choice, client encrypts their information utilizing homomorphic encryption. But it is lagging to reduce computation time and needs an additional security so we adopt and utilize elliptic curve digital signature algorithm (ECDSA). This additional encryption method gives the high security during transmission of data and also avoids bandwidth, less computation time and finally less storage space attained on both the sides.
