Efficient certificateless convertible limited verifier signature scheme
Zhou Xuan-wu · Computer Engineering and Applications Journal · 2009
Limited verifier signature can solve the conflict between authenticity and privacy in the digital signature.This paper proposes a new certificateless convertible limited verifier signature which is provably secure under the random oracle model and the CDH assumption.This paper shows that the scheme satisfies all the requirements of the limited verifier signature schemes in the certificateless system.Comparing with the existing schemes,the new scheme is more efficient in computation.
