Functional Message Authentication Codes With Message and Function Privacy
IET Information Security, Volume 2024, Issue 1, 2024.Functional signatures were allowed anyone to sign any messages in the range of function f, who possesses the secret key skf. However, the existing construction does not satisfy the property of message and function privacy. In this paper, we propose a new notion which is called functional message authentication codes (MACs).

Lattice-Based Revocable Certificateless Signature
Symmetry, 2017 Certificateless signatures (CLS) are noticeable because they may resolve the key escrow problem in ID-based signatures and break away the management problem regarding certificate in conventional signatures. However, the security of the mostly previous CLS schemes relies on the difficulty of solving discrete logarithm or large integer factorization ...

Certificateless signature scheme without random oracles
Tongxin xuebao, 2015 The security of certificateless signature schemes can be proved under the random oracle model.However，any implementation of the random oracle may result in insecure schemes.Some certificateless signature schemes without random oracles are not secure ...
