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.
