Title:
Comparing Two Pairing-Based Aggregate Signature Schemes
Authors: Sanjit Chatterjee, Darrel Hankerson, Edward Knapp, Alfred Menezes
Abstract:In 2003, Boneh, Gentry, Lynn and Shacham (BGLS) devised the first provably-secure aggregate signature scheme. Their scheme uses bilinear pairings and their security proof is in the random oracle model. The first pairing-based aggregate signature scheme which has a security proof that does not make the random oracle assumption was proposed in 2006 by Lu, Ostrovsky, Sahai, Shacham and Waters (LOSSW). In this paper, we compare the security and efficiency of the BGLS and LOSSW schemes when asymmetric pairings derived from Barreto-Naehrig (BN) elliptic curves are employed.
