AC ertificateless Signature Scheme based on Bilinear Pairing Functions
Routo Terada, Denise Goya · 2007
We construct a Certificateless Public Key Signature scheme - CL-PKS, i.e., a crypto- graphic signature scheme which does not require any Digital Certificate to verify a signature generated by a private key, based on asymmetric bilinear pairing functions. Our scheme does not allow the so-called key escrow. We analyze both its efficiency and security: it is more efficient than previously published CL-PKS schemes, with shorter signatures and public keys; we prove it is strong against adap- tively chosen message attacks, based on the computational difficulty of the Diffie-Hellman Problems.
