Abstract
Cloud computing is an important storage platform being researched nowadays. It provides various services to its users. Among them, one of the salient service offered is cloud storage which makes data outsourcing a rising trend. But the major concern associated is the integrity and seclusion of outsourced data. Users require their data to be secure from any modification or unauthorized access. Therefore someway to verify whether the data is intact or not, without retrieving, should exist. This boosts the need of secure remote data auditing. This paper proposes an auditing scheme based on vector commitment, identity based ring signature and group key agreement protocol, emanated on bilinear pairing. An experimental analysis of the proposed scheme, later in the end, shows that when compared with its pertinent schemes, the proposed scheme is also efficient.
