Data security management with minimized computational cost through signcryption and relocation techniques over a cloud

Abstract

Secure data transmission and storage is one of the major aspects from cloud computing aspect. In today s era cloud computing is becoming popular as it gives variety of users an extra hand. So for a cloud service provider it is a challenging job to ensure the clients about security and integrity of their data. The classical method for such type of security is costly from algorithm point of view. In the paper a method of dual level data security for secure transmission and storage with reduction in computational cost is being used. The paper constitutes a technique of signature then encryption in a single algorithm at the first level and relocation data at data center at the second level is proposed.
