    摘要： A system and method for generating a security indicator on a display of a computing device (e.g. a mobile device), to indicate when the computing device is in a secure state while locked. A determination is made (e.g. by a data protection system) as to whether at least some of the secure data stored on the computing device can be decrypted by any applications on the computing device, while the computing device is in the locked state. An icon or other identifier can be displayed to indicate that the secure state has been attained. In one embodiment, the secure state is considered to have been attained, if it is determined that all tickets that have been issued to applications on the computing device while the computing device was unlocked have been released, and any decrypted encryption keys that may be used to decrypt the secure data have been deleted.

    摘要： A system and method for generating reproducible session keys in a wireless messaging system. The session key is generated based on a hash of a message itself, optionally concatenated with additional information. Since the local server stores the message, it can easily regenerate the same session key in response to each MORE request. The method of the invention can be implemented with the stored original message, a public key, and an algorithm for generating the session key based on a hash of the message.

    摘要： Authentication of two devices in communication with a third device is achieved where the first and second devices each possess a shared secret value. The authentication includes communication of authentication values from the first device to the second device using the third device. Similarly, there is communication of values from the second device to the first device using the third device. The third device retains the communicated values. The values are calculated to permit the third device to authenticate the first and second devices without the third device receiving the shared secret value. The authentication may be used to establish a communications channel between the first and the second devices.
