A Novel Certificateless Aggregate Signature Scheme without Bilinear Pairings
Xiao TIAN · 2017
Most of the aggregate signature schemes are based on identity public cryptosystem that these identity-based aggregate signatures have certificate management and key escrow problems.And most of these schemes use the bilinear pairings and efficiency is not high.A novel aggregate signature scheme (CLAS-BP) is proposed based on the certificateless public key cryptography theory.This scheme solves the key escrow problem of the identity-based public key cryptography and not uses the bilinear pairings.The analysis shows that this scheme provides a high security and efficient.
