Resumen de Trust Model and Regulatory Guidelines of Certificate Authority in Thailand
This paper compares the certificate policy (CP) and certificate practice statement (CPS) which describe work processes conducted by three major Certificate Authorities (CA) in Thailand. Although CA is the main component in e-Commerce infrastructure, Thailand still lags behind many developed economies. Each CA is operating independently without any recognition across CAs. The burden is borne by the users who need to install public keys of those whom they communicate. In addition, there is no clear regulation governing CA business. The paper proposes five possible Trust Models to bridge recognition among CAs. Opinion survey among government IT personnels, however, supports the role of Ministry of Information and Communication Technology as the National Root CA.This paper compares the certificate policy (CP) and certificate practice statement (CPS) which describe work processes conducted by three major Certificate Authorities (CA) in Thailand.
