New Identity-based Short Signature Without Random Oracles
Leyou Zhang, Yupu Hu, Qing Wu · Procedia Engineering · 2011
A new identity-based short signature(IBS) is proposed in this paper. The new scheme is constructed in the standard model and has short public parameters and private keys. In addition, the size of the signature achieves 320 bits, which is much more efficient than the existing IBS schemes. Under the n-Computational Diffie-Hellman Exponent Problem(n-CDH), the new scheme is provable security.
