A scheme of issuing inter-domain trust certificate based on proxy signature

Abstract

To solve the problem of carrying trust value, we use trust certificate which is issued by the Trust Management Center in the Trust Management System to carry it. Each Trust Management Center should only be in charge of auditing and issuing trust certificate in its own domain. Face to the problem of how to get an inter-domain trust certificate, we provide a scheme that apply the proxy signature to generate trust certificate. This scheme can solve the problem of issuing trust certificate in inter-domain efficiently.
