Certificateless signature scheme without random oracles [PDF]
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 ...
