Multi-domain signcryption algorithm for communication of mobile Ad hoc networks

In order to insure the security of communication in mobile Ad hoc networks, a new signcryption scheme with multiple private key generators was proposed. The proposed scheme was based on bilinear pairing and identity cryptography, it is suitable for multi-domain Ad hoc networks. Under the assumption that the computational Diffie-Hellman is difficult, the security of the scheme has been proved under the random oracle model. It is concluded that the proposed scheme satisfies the security requirements of Ad hoc networks and has less computation and storage requirements.
