Enabling Indirect Mutual Trust and Secure Login Mechanism for Cloud Computing Storage Systems

Yasha Gawande | Shilpa Gite ^[2]

Abstract: In this era, management of huge amount of data is difficult on local machine. Hence many companies are outsourcing their data over remote cloud servers to lessen the storage load. But outsourcing huge amount of sensitive data to cloud servers is risk as cloud servers are untrusted. This work assist user to store data in the form of blocks. The outsourced data should be guaranteed with confidentiality, integrity and access control. In this paper, we propose a scheme which assures these security issues. Also the CSP, data owner and the users share untrust relation, hence trust between these parties is maintained by using a trusted third party (TTP) which has capability to detect and notify fraud party. This paper presents a scheme assuring access control by which data owner can grant or revoke access right to set of users. This cloud storage scheme uses concept of OTP to assert secure login at entry level. Current cloud scheme uses only login id and passwords but using OTP sent over email mitigates the chances of insecure login as OTP can be used only once.
