A Galindo-Garcia-Like Identity-Based Signature with Tight Security Reduction, Revisited

Published: Nov 1, 2018
Abstract
Galindo-Garcia identity-based signature (GG09 IBS) is an efficient identity-based signature (IBS) based on Schnorr signature scheme. The security of GG09 IBS is proven in the random oracle model under the discrete-log assumption, however, the security proof achieves a loose security only. In CANDAR'17, Fukumitsu and Hasegawa proposed a GG09-like IBS (FH17 IBS). Although their scheme achieves a tight security in the random oracle model under the...
