초록

대리서명은 원서명자가 자신의 서명 권한을 대리 서명자에게 위임하여 대리 서명자가 원서명자를 대신해서 서명을 생성하는 것을 말한다. 대리서명은 원서명자가 위임 정보에 대한 서명을 생성하고 이를 위임자에게 전달하여 위임자가 위임키로서 사용하게 하는 것이다. 본 논문에서는 원서명자와 대리서명자가 기존의 인증서를 발급 받은 환경에서 원서명자가 대리서명자에 대하여 검증자에계 위임정보를 등록하는 프로토콜을 제안한다. 위임내용에 대해 원서명자가 디지털 서명을 하고 검증자는 이에 해당하는 내용을 검증한 후 위임서명자에 대한 권한, 기간 등의 제약사항을 설정하고 허가된 범위 내에서 위임 서명을 한다.

Proxy signature is the signature that an original signer delegates his signing capability to a proxy signer and the proxy signer creates a signature on behalf of the original signer. The basic methodology of proxy signature is that the original signer creates a signature on delegation information and gives it secretly to the proxy signer, and the proxy signer uses it as a proxy private key or uses it to generate a proxy private key. In this paper, we suggest the proxy-register protocol that the original signer register to the verifier about the proxy related information, and verifier sets the warrant of proxy signer, validity period for proxy signature and some limitation.
