Public Key Infrastructure

A robust, flexible, standard, and open Public-Key Infra-structure Architecture is critical to the success of secure systems based on Public-Key technology.

The Open Group have begun to work with experts in other organisations, (IETF, CommerceNet, European Commission funded projects, etc.), to define a common architecture for a public key infrastructure. This will make use of existing standards in The Open Group and the IETF for instance, and will identify gaps in the infrastructure that need to be filled. The Open Group also intends to work with other organisations to encourage early commercial implementations and pilot trials.
