Public Key Infrastructures That Safisfy Security Goals



William T. Polk, Nelson E. Hastings, A Malpani


This article describes the features of different PKI architectures, and the motivations behind their use. While some PKI architectures (e.g., hierarchies) are very simple, political and social realities encourage deployment of more complex (e.g., mesh) PKIs. The validation authority is a direct response to the complexity of these architectures and an opportunity for organizational control. The movement towards interconnection of PKIs using Bridge CAs gains momentum as organizations seek to leverage their infrastructure investments. The complexity of the resulting PKIs provides incentives for deployment of shared validation authorities, relinquishing organizational control for economies of scale
