Abstract:

 Certificate-based cryptography is a new public key cryptographic paradigm that has many appealing features since 
it simultaneously solves the certificate revocation problem in conventional public key cryptography and the key escrow 
problem in identity-based cryptography. Till now, three certificate-based Authenticated Key Agreement (AKA) protocols have 
been proposed. However, our cryptanalysis shows that none of them is secure under the public key replacement attack. To 
overcome the security weaknesses in these protocols, we develop a new certificate-based AKA protocol. In the random oracle 
model, we formerly prove its security under the hardness of discrete logarithm problem, computational Diffie-Hellman 
problem and bilinear Diffie-Hellman problem. Compared with the previous proposals, it enjoys lower computation overhead 
while providing stronger security assurance. To the best of our knowledge, it is the first certificate-based AKA protocol that 
resists the public key replacement attack in the literature so far.
