    摘要: A system and method for retrieving certificates and/or verifying the revocation status of certificates. In one embodiment, when a user opens a digitally signed message, a certificate that is required to verify the digital signature on the message may be automatically retrieved if it is not stored on the user's computing device (e.g. a mobile device), eliminating the need for users to initiate the task manually. Verification of the digital signature may also be automatically performed by the application after the certificate is retrieved. Verification of the revocation status of a certificate may also be automatically performed if it is determined that the time that has elapsed since the status was last updated exceeds a pre-specified limit.

    摘要: Systems and methods for processing messages within a wireless communications system are disclosed. A server within the wireless communications system maintains a list of certificates contained in devices that use the server. The server synchronizes or updates the list of certificates based on information contained in message to and from the device. By providing a server with certificates associated with devices that use the server, and providing a system and method for synchronizing the certificates between the device and server, the server can implement powerful features that will improve the efficiency, speed and user satisfaction of the devices. The exemplary embodiments also enable advantageous bandwidth savings by preventing transmission of certificates unnecessarily.
