Overview:

Interoperability between PKIs (Public Key Infrastructure) is a major issue in several electronic commerce scenarios. This paper suggests an approach based on a trust model where an independent Validation Authority (VA) replaces Certification Authorities (CA) as the trust anchor for the receiver of a PKI certificate (the Relying Party, RP). By trusting the VA, the RP is able to trust all CAs that the VA can answer for. The main issue is not technical validation of the certificates but assessment of quality, trustworthiness and risk related to certificate acceptance. The RP obtains a one-stop shopping service - one point of trust, one agreement, one bill, one liable actor, which may be beneficial for some business processes.
