On the Security of Certificateless Signature Schemes
International Journal of Distributed Sensor Networks, 2013 Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

Certificateless online/offline signcryption scheme
Security and Communication Networks, 2014 AbstractSigncryption is a highly efficient approach to achieve simultaneously confidentiality and authentication of message, which is more feasible than the simple combination of encryption and signature. The online/offline cryptography can further enhance the efficiency of signcryption system process without affecting its security.

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 ...
