An Aggregate Signature Scheme with Forward Security and Non-repudiation

Abstract

Based on bilinear pairing, elliptic curve and strong RSA assumption proposed a new aggregate signature scheme with forward security. The traits of the scheme is as follows: It have the non-repudiation, which realized the authentication between the secret key generation center and users; Have the forward security, based on the strong RSA assumption implementing the security of signature information, and to further guarantee the system's security.
