ABSTRACT

As the E-commerce and E-business are developed actively, using certificate is incremented rapidly. The certificate validation must be confirmed at first in E-commerce and the OCSP Responder can offer CSI to the client using OCSP. With the rapid development of the E-commerce based on the Internet, a lot of clients request CSI to OCSP Responder. So, the load to OCSP Responder is increased and the OCSP Responder may be overloaded. Therefore, for distributing the load to an OCSP Responder, D-OCSP is introduced. As the CRL has a lot of information about revoked certificates and have a high exposure possibility of information in the process of distribution, the confidentiality as well as integrity are required in the process of distribution. So, we propose a CRL distributing method based on group key agreement in D-OCSP. The proposed method can distribute effectively a published CRL to OCSP Responders with confidentiality as well as integrity and offer concurrency that each OCSP Responder can start CSI servicing of new CRL to clients at the same time.
