System for providing certification confirming agency service using double electronic signature
First Claim
1. A system for providing a certification confirming agency service using a double electronic signature, comprising:
- a transmitting mobile terminal for receiving a message from a user, performing a security function required for message encoding and electronic signature of a sender, and performing a message transmitting function;
an application service system for receiving the message transmitted from the transmitting mobile terminal, requesting a validity check of a sender'"'"'s certificate and a sender'"'"'s certification check to a certification confirming agency system, and receiving from the certification confirming agency system and transferring to a receiving mobile terminal a message of the certification confirming result;
the certification confirming agency system for receiving a request for confirming the validity of the sender'"'"'s certificate and a sender'"'"'s signature value from the application service system, extracting the validity of the sender'"'"'s certificate and the sender'"'"'s signature value by analyzing a statement transmitted from the transmitting mobile terminal through the application service system, performing the validity check with respect to the sender'"'"'s certificate and signature value, and transmitting a result of checking with its signature attached thereto back to the application service system;
the receiving mobile terminal for restoring the transmitted statement by receiving and decoding the message from the application service system, and outputting a restored statement so that a receiver can view it;
a certificate issuing system for issuing electronic certificates to mobile terminal users; and
a certificate directory system for noticing the electronic certificates issued by the certificate issuing system so that wire/wireless subscribers can peruse them through a wire network and a radio network.

Abstract
Disclosed is a system for providing a sender certification service based on an end-to-end (EtoE) message security and public key infrastructure (PKI) between mobile terminals. The system performs by proxy a verification work of the user'"'"'s certificate that is difficult to be performed by the mobile terminal having a limited capacity. The system performs by proxy a certification removal list (CRL) check and a certificate validity check with respect to the certificate sent by a sender, and thus the mobile terminal having the limited capacity can directly use the certificate without any CRC check or validity check of the sender'"'"'s certificate, and effectively perform the PKI based electronic certification service. The system can be usefully applied to all fields that require a PKI based certification security service in the radio network environment in that messages are transmitted/received between the mobile terminals.
