ABSTRACT
An enterprisewide security architecture, including technology, appropriate security policies, and audit trails, can provide reasonable measures of risk management to address senior management concerns about E-business opportunities. One technology involved in enterprisewide security architectures is public key cryptography, often implemented in the form of a public key infrastructure (PKI). This article describes several hands-on examples of PKI, including business cases and implementation plans. The authors
attempt to present detail from a very practical, hands-on approach, based on their experience implementing PKI and providing large-scale systems integration services. Several shortcuts are taken in the technical discussions to simplify or clarify points, while endeavoring to ensure that these did not detract from the overall message.
