Identity-Based Authentication in Cloud Storage Sharing
This paper aims at the heavy load of thin client in cloud storage sharing due to traditional mutual authentication scheme with inherent public-key operation and interaction for many times, and proposes an Identity-Based Authentication (IBA) scheme which is of short key size, identity-based, noninteractive. This scheme divides the sharing users into the very same domain and in this domain relies on the sharing global master key to exercise mutual authentication. By analysis of performance, we can find user-side performance is improved for over two times both in computational cost and in communicating cost. The IBA scheme can be enabled by an emerging cryptographic technique from the bilinear pairing and its security can be assured by the Bilinear Diffie-Hellman Problem (BDHP).
