Universally Verifiable Certificateless Signcryption Scheme for MANET

The mobile ad hoc network (MANET) is a collection of wireless mobile nodes that communicate with one another through a standard transmission medium such as Wi-Fi, cellular, or satellite communication. However, their basic characteristics make them vulnerable against numerous attacks accordingly raising the need of security. In this paper, we propose a certificateless signcryption scheme based on the difficulty of solving the Diffie-Hellman problem. The simulation result proves that the scheme is secure against active and passive attacks using AVISPA (Automated Validation of Internet Security Protocols and Applications) tool.
