The security model of the certificateless aggregate signature scheme with universal designated verifier was studied
and then a certificateless aggregate signature scheme with universal designated verifier using bilinear pairings was proposed.In the random oracle mode
based on the hardness of the computational Diffie-Hellman problem
the new scheme was proved to be secure against three attacks of certificateless aggregate signature scheme with universal designated verifier.Meanwhile
the scheme satisfies properties of strong designated verify and non-transferability.Furthermore
the length of final aggregate signature is equivalent as the length of signal user’s signature
it is more efficient than others because the pairing computation is fixed among public verifies and designed verifies.
