To investigate the potential for international harmonization of policy requirements for CAs. This relates to the work in the US and other international activities specifying security management and policy requirements for CSPs issuing certificates (qualified or other) to ensure harmonization with the European standardization in this area. As well as influencing these other international activities, this work will identify variations in the requirements as specified in ETSI TS 101 456 (?Policy requirements for CA issuing qualified certificates?). This activity will include discussions and where possible achieve harmonisation with relevant organisations such as: ABA, FPKI, IETF, PKI Forum, WAP Forum.
