Abstract: Security over the Internet depends on a clear distinction between authorized and un-authorized principals. Discriminating between the two involves: identification (user identifies himself/herself), authentication (the system validates the user's identity) and authorization (specific rights granted). Thus, it is important to develop specifications for access control that realize the above properties with ease. Public Key Infrastructures (PKIs) provide a basis for specifying access-control to the users in a secure and non-reputable fashion. Some of the general deficiencies of PKIs are: (i) they are rigid and cannot scale across different PKI frameworks, (ii) due to efficiency reasons, PKIs are constrained to be just static data-structures shipped across domains and hence cannot carry any dynamic or state-based information, and (iii) for reasons of (ii) the recipients are not explicitly defined. In this paper, we shall argue that a judicious mix of digital certificates and authenticatio n mechanisms would lead to a flexible security policy specification having both static and dynamic capabilities and lead to user-friendly mechanisms to achieve availability of secure services in e-commerce.
