To alleviate the influence of key exposure, we combine forward-security with certificate-based cryptography and give formal definitions and the security model of forward-secure certificate-based signatures. Then we propose a forward-secure certificate-based signature scheme, which is proven to be existentially unforgeable against adaptive chosen message attacks in the standard model. Hence, we partially solve the key exposure problem in certificate-based signature scheme and improve the system security. © 2012 Springer-Verlag.
