Abstract: We extend PubKey-Wiki, a public key-based group collaboration system, with a hybrid certificate closure-chain discovery public key architecture. PubKey-Wiki introduced a certificate closure algorithm that computes the transitive closure of a set of certificates that contain authorisation information. In this paper, we introduce a hybrid PubKey-Wiki system that combines both the certificate closure algorithm and a certificate chain discovery algorithm in a new architecture that leverages the strengths of both algorithms.

Keywords: authorisation rules; certificate chain discovery; certificate closure; delegation; hybrid architecture; public keys; group collaboration; security.
