摘要：Certificate-based cryptography proposed by Gentry in Eurocrypt 2003 combines the advantages of traditional public key cryptography (PKI) and identity-based cryptography, and removes the certificate management problem and the private key escrow security concern. Based on computational Diffie-Hellman assumption, a certificate-based signature scheme is constructed to insure the security of communication in mobile Ad hoc networks,. The security of the scheme is proved under the Random Oracle Model. The scheme is also efficient, since the signing algorithm does not need the computation of the bilinear pairing and the verification algorithm needs that computation only once. Thus it is particularly useful in Ad hoc networks.
