Abstract

Information security and trust are the most important factors to be considered in e-commerce and e-business transactions. The protection and distribution of valuable information that is needed in a widely pervasive environment is the main goal of modern security architectures. The users, resources and the information are spread across di�erent places. The users need information at di�erent times. Eventhough there are many solutions to improve the quality of security services, there is a signi�cant opportunity to improve those services in e-commerce and ebusiness applications. The emerging approach to address the security needs makes use of the scalable and distributed characteristics of Public Key Infrastructure. Public Key Infrastructure (PKI) is one of the solutions to use the security services in a useful way. PKI is a frame work on which the security services are established. A PKI binds user's Public Key with a data structure called Public Key Certi�- cate or Digital Certi�cate. It can provide various secure services in e-commerce and e-business transactions. A number of security related services like end entity authentication, data integrity etc. are supported by PKI and this needs a proper utilization of the key pairs generally used in PKI i.e., public or private key pairs. Each company willing to transmit its critical data safely over the internet has to deploy a PKI. X.509 PKI systems are the most popular PKI systems deployed in enterprises. The systems have evolved from simple single CA(Certi�cation Authority) PKIs, to complex enterprise PKIs, to cross-certi�ed PKIs, and now to bridge technology. There are di�erent types of PKI models which are also called trust models. One of the popular and most commonly used trust models is the Hierarchical PKI model. Since each company deploys its own security infrastructure, there arise interoperability problems during communication with other companies. During merger and acquisition of companies, the multiple PKIs deployed by them must be interoperated. Interoperability is viewed both by customers and industry analysts as a critically important issue for PKI. PKI interoperability o�ers greater
