An Effective User Revocation and Anti - Collusion System for Dynamic Groups in Cloud
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
The objective of the project is to develop a simple and effective collusion resistant dynamic group model for cloud. The workloads in cloud often contain sensitive information. The major problem in public clouds is to securely share the data in dynamic groups while also conserving data and uniqueness. This is because, revocated users from the group should not able to access the original data as well as the data being shared in the group. This problem is called collusion attack. The existing systems use few encryption techniques such as ECC to prevent the collusion attacks but when implementing such a system, the drawback is actually in choosing which curve or family of curves to deal with, because every application will have diverse requirements and also no elliptic curve can be optimal for every other application thus making the ECC algorithm complex and difficult to the core. Hence we present a new secret sharing scheme which is comparatively simpler, efficient and easier to implement. This scheme has an efficient membership re-vocation method by avoiding the overhead of updating the secret keys of the users every time thus minimizing the complexity of key management, and also the computational cost.
