摘要： A system and method are provided for pre-processing encrypted and/or signed messages at a host system before the message is transmitted to a wireless mobile communication device. The message is received at the host system from a message sender. There is a determination as to whether any of the message receivers has a corresponding wireless mobile communication device. For each message receiver that has a corresponding wireless mobile communication device, the message is processed so as to modify the message with respect to one or more encryption and/or authentication aspects. The processed message is transmitted to a wireless mobile communication device that corresponds to the first message receiver. The system and method may include post-processing messages sent from a wireless mobile communications device to a host system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the host system to one or more receivers.

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

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 encoded messages within a wireless communications system are disclosed. A server within the wireless communications system determines whether the size of an encoded message is too large for a wireless communications device. If the message is too large, the server removes part of the message and sends an abbreviated message to the wireless device, together with additional information relating to processing of the encoded message, such as, for example, hash context values, that assist the wireless communications device in verifying the abbreviated message.

摘要： A method and apparatus for providing intelligent error messaging is disclosed wherein a user of a mobile communications device is provided with descriptive error messaging information to assist the user in overcoming errors associated with the processing of electronic messages and data. For example, when the mobile device is being used to decrypt a cryptographically secured electronic message, and a problem is encountered, program logic of the device provides the user with (1) an indication of exactly what problem is preventing opening of the message, for example, a required cryptographic key is not available; (2) an indication of exactly what may be done to overcome the problem, for example, what utilities should be run on the device; and (3) exactly what data, if any, needs to be downloaded to the device, for example, what cryptographic keys should be downloaded.
