Abstract:

Background: Collusion resistance is preserving the value generated at individual nodes secret so that if any nodes share the information together or collude with each other, the secret values cannot be revealed.It is really a challenging task to securely resist the collusion of cloud server and users Collusion resistance also involves growing the number of people.

Objective: Users can achieve an effective and economical approach for data sharing among group members in the cloud with the characters of low maintenance and little management cost.

Methods: Hybrid Cache supported One way hash chain technique.

Results: To test with the sparse caching HHCS and one-way hash chain model and the various sparse caching configurations are fully implemented by this work. Multiple situations and various scenarios are considered in the experiments and tests for the estimation of HHCS’ performance. The results which are measured in terms of storage units needed for the completion of one internet session and in terms of efficiency (which is the number of hash operations done in one session) are compared and then contrasted.

Conclusion: Security improvement is proposed in this paper in group key management method, in order to solve the issue of collusion attack between whole members of the group for a secure group communication. It is shown that using lightweight is easy for the implementation of sparse caching method which can greatly improve the cryptographic one-way hash chain method’s performance which is used widely, for securing the transmission of data in cloud by using two levels of security scheme. A memory-times computation complexity metric has been introduced to help choose the best size of cache depending on storage requirements of the cloud application. For demonstrating various connection behaviors, various cache spacing methods have been evaluated. This paper presented and evaluated the potential of hybrid solution in which one-way hash chains which are divided are provided with caching capacities in order to store the values of session key and retrieve them when needed for authenticating a user session. Lower computational overhead is achieved by us as measured by the count of hash operations and computation time needed to give protection.
