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. Selected certificates may be downloaded to the computing device for storage, and the downloaded certificates are tracked by the data server. This facilitates the automatic updating of the status of one or more certificates stored on the computing device by the data server, in which updated status data is pushed from the data server to the computing device.

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 encryption and/or authentication aspect. 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 remote system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the remote system to one or more receivers.

A system and method for securing data for redirecting and transporting over a wireless network are generally described herein. In accordance with some embodiments, when it is determined that an electronic message that is protected with a first encryption algorithm is to be transported over a wireless network to a wireless device, the electronic message is converted to a data structure that is recognizable by the wireless device and the data structure is encrypted with a second encryption algorithm using a random session key. The second encryption algorithm has a stronger security than the first encryption algorithm. The random session key is encrypted with a public key and packets that comprise the encrypted data structure and the encrypted random session key are transmitted to the wireless device over the wireless network.

Embodiments relate to systems and methods for implementation on a mobile device to force the mobile device into a secure state upon detection or determination of a triggering event. Once it is determined that a triggering event has occurred, each application operating on the mobile device is caused to immediately unreference sensitive objects and a secure garbage collection operation is performed upon the unreferenced sensitive objects to render data associated therewith unreadable. The mobile device is then caused to enter a secure state, in which the mobile device cannot be accessed without authorization. A microprocessor within the mobile device is configured to determine the existence of the triggering event according to a configuration data structure and to perform the secure garbage collection.

A system and method of selecting messaging settings on a messaging client are provided. A data store configured to operate in conjunction with the messaging client stores records comprising messaging settings or characteristics for previously received and/or sent messages. The messaging client is configured to send outgoing messages, each of the messages having message characteristics, to determine whether a record for an addressed recipient of an outgoing message exists in the data store, and to select messaging settings to control the message characteristics of the outgoing message based on the record where a record exists.

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.

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.

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:
A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret. First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.
