    摘要: A system and method for processing certificates located in a certificate search. Certificates located in a certificate search are processed at a data server (e.g. a mobile data server) coupled to a computing device (e.g. a mobile device) to determine status data that can be used to indicate the status of those certificates to a user of the computing device, without having to download those certificates to the computing device in their entirety. The data server is further adapted to transmit the status data to the computing device. In one embodiment, at least one status property of the certificates is verified at the data server in determining the status data. In another embodiment, additional certificate data is determined and transmitted to the computing device, which can be used by the computing device to verify, at the computing device, at least one other status property of the certificates.

    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.

    摘要: Systems and methods for providing additional security for data being transmitted across a wireless connection that has been established using a known wireless protocol (e.g. Bluetooth) are described. An encryption key is exchanged between a computing device (e.g. a mobile device) and a wireless peripheral device (e.g. a keyboard, a printer). In some embodiments, the encryption key is generated at one of the two devices. Data associated with the encryption key is output at the one device, which can be input by the user at the other device. The encryption key is then recovered at the other device from the input, thereby completing the key exchange. The encryption key can then be used to encrypt and decrypt data transmitted over the established wireless connection, providing additional security.

    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.
