The Research On Key Technologies Of LDAP Server

LDAP protocol is an important protocol used for data query in Internet, in the PKI infrastructure,LDAP is used for query and download certificate and CRL,it has extensive and important application.The research on key technologies of LDAP server is divided into two parts in this paper: Achieved digital certificate stored ,queried and download in LDAP; the research on certificate revocation algorithm.In the part of digital certificate stored, we design a metadata management method which improve the efficiency of query.In the digital certificate revoked stage, we have designed a way which integrates Delta and over-issued CRL and windowed certificate revocation mechanism. Through analysis showed the advantage of this method. Finally, the LDAP system applies to the simple power system can help trade transactions to query more convenient, more security in the network.
