The protocol’s specification focuses on the communication between the server and the client and its security. It does not discuss how the servers can efficiently locate the necessary PKI resources like certificate or certificate revocation lists. In this paper we concentrate on this topic. We present a simple and effective method to facilitate locating and using various PKI resources by the servers, without modifying the protocol. We use the extension mechanism of the protocol for notifying the servers about PKI repositories, certificates, and revocations. We specify the tasks of the servers and certificate issu-ers and define the messages that are exchanged between them. A proof of concept is given by implementing an SCVP server, a client, and the proposed method in Java.展开更多

At present, the number of certified welding fabrication companies is still small. However, more and more enterprises are getting to realize the importance, and we have already had the following basic conditions: welding personnel qualification according to the international guidelines and rules, welding standards equivalent to ISO and EN standards, as well as full successful experiences of company certification gained through cooperation between China and Germany. So with additional industries’ support and government’s attention, company certification according to international rules will provide qualification guarantee for welding fabrication companies to participate in international market competition.展开更多
