위임 인증서를 이용한 권한 위임 메커니즘 설계

Abstract

In real life, we frequently use th proxy signatrue by delegating one`s own privileges. It is necessary to distribute the data related to privilege delegation securely in order to use such a proxy signature in the Internet. However, inorder to use the secure proxy signature, we need to have some mechanism to prevent a proxy signer from misuse of privileges by applying proxy certificate and a privilege delegation mechanism to manage information with related to privilege delegarion. In addition, we have implemented the prototype to demonstrate the possible proxy signature service using proxy certificate.
