SYSTEM AND METHOD FOR SENDING SECURE MESSAGES

摘要

Electronic messages are sent from a sending system to an identified recipien t and are encoded using information contained in a certificate. A key store is accessed by a messaging application to determine if a certificate associated with the recipient is present. If no certificate is present in the key store the messaging application accesses one or more certificate services to obtai n a certificate. Where validation of the retrieved certificate is required, th e messaging application invokes a certificate validation process. One or more further certificates are obtained by the messaging application where the retrieved certificate is invalid.
