Abstract
A participant ( ) in electronic commerce can validate his/her own certificate ( ) by accessing an authority ( ) that checks whether the participant's certificate is valid. If the certificate is valid, the authority embeds with the participant's terminal ( ) a block of data, in the form of a Cookie ( ) that includes a plurality of attributes indicative of the certificate, for example, the certificate's date of expiration. When accessing a secure application ( ), the participant presents both the certificate and the authenticating Cookie, obviating the need for a real-time inquiry to the authority, unless the Cookie is stale or missing.
