An Efficient Fine-Grained Access Control and the Verifiable Delegation in Cloud Computing

Abstract

Recently, a few studies considers the hassle of comfy and efficient public information integrity auditing for shared dynamic statistics. But this scheme isn't cozy towards collusion of cloud storage server. An efficient public integrity auditing with a secured organization user revocation based totally on vector commitment and institution consumer revocation. A dispensed key technology algorithm is used to generate authenticated person passwords across a couple of servers and eliminate unmarried factor failures. This scheme helps the public checking and efficient person revocation and also affords confidentiality, efficiency and traceability of relaxed institution user revocation. A homomorphic encryption algorithm is also used for growing particular id for the users. In this paper we propose a concrete circuit ciphertext-coverage attribute-based hybrid encryption with verifiable delegation scheme based totally on the multilinear maps and the verifiable computing technology beneath cloud environment.
