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 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 searching and retrieving certificates, which may be used in the processing of encoded messages. In one embodiment, a certificate synchronization application is programmed to perform certificate searches by querying one or more certificate servers for all certificate authority (CA) certificates and cross-certificates on the certificate servers. In another embodiment, all certificates related to an identified certificate are retrieved from the certificate servers automatically by the certificate synchronization application, where the related certificates comprise at least one of one or more CA certificates and one or more cross-certificates. Embodiments of the invention facilitate at least partial automation of the downloading and establishment of certificate chains, thereby minimizing the need for users to manually search for individual certificates.
摘要:
A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one broad aspect, a method is provided in which a certificate search request is received, a search of one or more certificate servers for certificates satisfying the request is performed, located certificates are retrieved and processed at a first computing device to determine data that uniquely identifies each located certificate, and search result data comprising the determined data is communicated to a second device (e.g. a mobile device) for use in determining whether each located certificate is already stored on the second device.

A communication device (and its related method of operation), when accessing password protected voicemail services, may invoke an enhanced security feature which effectively masks at least the password digit values from being discernible by feedback to the user. This is especially important where portable wireless communication devices may have pre-stored password data for use with automated voicemail access—even in a “locked” mode. Unauthorized possessors of such a device might utilize conventional audible feedback during password transmission to decipher the password value. However, such lack of security is avoided by masking the password data values from the audible and/or visual user feedback, if any.

A method and system for Certificate management and transfer between messaging clients are disclosed. When communications are established between a first messaging client and a second messaging client, one or more Certificates stored on the first messaging client may be selected and transferred to the second messaging client. Messaging clients may thereby share Certificates. Certificate management functions such as Certificate deletions, Certificate updates and Certificate status checks may also be provided.

The present disclosure relates generally to the management of privileges associated with certain applications that are accessible by users of electronic equipment, such as, for example, networked computers, mobile wireless communications devices, and the like. In particular, the disclosure is directed to systems and methods for managing privileges associated with particular applications and for revoking these privileges in a timely and robust manner. For example, the device keeps track of which applications get access to which privileges. When policies or application control changes, the system detects which privileges have been revoked for which applications. This can be accomplished by simply comparing the old set of privileges with the new set of privileges. For each revoked privilege for a given application, the system determines if the application has ever accessed that privilege in the past. If an application has accessed a privilege that is now revoked at any time in the past, the device is reset. To ensure that privileges that may be passed between applications are not overlooked, the device is arranged to perform a reset if any revoked privilege accessible by the device is one that may be passed between applications.
摘要:
A system and method for sending encrypted messages to a distribution list that facilitates the sending of such messages only to individuals or other entities associated with the distribution list that will be able to read the message. In one embodiment, the method comprises the steps of: identifying a distribution list address in a message; determining one or more member addresses associated with the distribution list address; for each member address, determining if a public key for a member identified by the respective member address is available on the computing device; encrypting the message to each member identified by the one or more member addresses for which a public key for the respective member is available on the computing device; sending the encrypted message to the distribution list address if each of the one or more member addresses associated with the distribution list identifies a member for which a public key is available on the computing device; and sending the message to each of the one or more member addresses that identifies a member for which a public key is available on the computing device otherwise.
摘要:
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.

Preferred embodiments of the invention relate to a method and device for authenticating a user of a computer and a corresponding system using the method and device. The device is a handheld electronic device having accessible thereto a first authentication code of the user. The handheld electronic device requires a second authentication code for enabling use thereof. In order to authenticate the user to the computer, the handheld electronic device is configured to transmit the first authentication code to the computer over a communication link between the computer and the handheld electronic device.

Systems and methods of application control for use on an electronic device. A device can be configured to receive an operation request from an application. The device can determine whether the requested operation is allowed to be performed by the application based upon a stored authorization record and an application identifier associated with the application. The application is allowed to perform the requested operation based upon whether the requested operation is determined to be allowed to be performed by the application.
