Survey on Distributed Mobile Cloud Computing Services: Signature Scheme for a Privacy-Aware Authentication

In recent societies, the number of mobile users has tremendously risen in recent years. The paper provides security and use for mobile users to access different mobile cloud computing services from multiple service providers using only a single private key. In this paper, we propose a new short signature scheme from the bilinear pairings. However, our scheme is represented from Inverse Computational Diffie-Hellman Problem (Inv-CDHP) based on bilinear pairing and does not require any hash function. We give the exact security proofs for the new signature scheme and the ring signature scheme in the model.
