PKI域间互操作性研究

Research on PKI Inter-domain Interoperability

Internet作为电子商务和数字通信的基础平台面临着很多安全威胁.PKI技术为安全电子交易提供了保障.电子商务中,在不同的PKI域之间需要实现互操作.本文提出了一种不使用交叉证书的情况下连接多个独立的PKI域的新方法.该方法是将多个PKI域整合成一个PKI域来实现PKI域之间的互操作.本文采用形式化的方法来描述合并过程.

Internet has confronted with many security threats as an infrastructure of E-commerce and digital communications. PKI technology provides security protection for secure electronic transactions. In E-commerce, different PKIs need to he interoperated. This paper takes a different approach from cross- certification techniques toward merging different PKIs. This method is to merge the multiple CAs into one,Then we formalize merging processes.
