ISSRP: A secure routing protocol using identity-based signcryption scheme in ad-hoc networks

We present a secure routing protocol based on identity-based signcryption scheme in ad-hoc networks. Because the proposed protocol uses identity-based cryptography, it can eliminate storage consumption and a certificate of public key exchange. Also, our protocol has very short ciphertexts/signatures and efficient computation time than other protocols based on RSA because it uses pairings over elliptic curves. In addition, the signcryption scheme fulfills both the functions of digital signature and encryption, and it thus can give savings in computation cost and communication overhead.
