Abstract:
The X.509 hierarchical public key infrastructure model is used to distribute trust and to decentralize the responsibility of managing digital certificates among certification authorities. However, the trust indiscriminately flows through these certification authorities, allowing any of them to issue trusted certificates. Many works propose trust quantification and calculation as a solution for this problem, but most of them apply their proposed methods in hypothetical public key infrastructure networks. In this paper, we propose a plausible implementation of quantification and calculation of trust for the X.509 public key infrastructure, specifying ASN.1 structures and trust management procedures to initialize and update trust values in this model’s relationships.
