Classification as an approach to public key infrastructure requirements analysis

Abstract

Classification schemes and taxonomy of request have focused only on business or software requirements defined by general non-functional requests. Public key infrastructure (PKI), as a complex system, requires special attention in the process of identification and definition of requests in all parts of the system. Requests efficiently identified and defined are the basis for successful PKI development and implementation. This study proposes a new classification scheme of requirements that enable effective identification of PKI requests in all system development life cycle phases. The proposed classification scheme has been designed in a way that can be used both by organisations just introducing a PKI system in their business operations, as well as organisations developing and implementing the PKI. Although there are more classification schemes and taxonomy of requests, the proposed classification scheme is the optimum solution for identification and definition of PKI system requests, as well as a good basis for testing, verification and validation of the PKI final product.
