摘要:
Methods and systems for handling on an electronic device a secure message to be sent to a recipient. Data is accessed about a security key associated with the recipient. The received data is used to perform a validity check related to sending a secure message to the recipient. The validity check may uncover an issue that exists with sending a secure message to the recipient. A reason is determined for the validity check issue and is provided to the mobile device's user.

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 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 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.

A method of handling cryptographic information in a communication comprising body elements and attachment elements to a mobile device includes the steps of determining if the communication includes an attachment element comprising cryptographic information and converting the attachment element into a body element upon determining that the communication includes an attachment element comprising cryptographic information.

A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one broad aspect, certificate identification data that uniquely identifies a certificate associated with a message is generated. The certificate identification data can then be used to determine whether the certificate is stored on a computing device. Only the certificate identification data is needed to facilitate the determination alleviating the need for a user to download the entire message to the computing device in order to make the determination.

Embodiments of the systems and methods described herein facilitate the transmitting, receiving, and processing of encoded messages wherein the header fields in the message header are protected. In one embodiment, the contents of the header fields to be protected are inserted into the message body as one or more additional lines of text, for example, prior to encoding and transmitting the message to a message recipient. Upon receipt of the message, the message recipient processes the encoded message such that the contents of the protected header fields can be extracted from the message body. Accordingly, by inserting the contents of the header fields to be protected into the message body, the header fields may be protected using existing standards and protocols for facilitating secure message communication.

摘要:
Systems and methods for operation upon a data processing device for handling messages with different levels of security, are provided herein. A method for operation upon a data processing device for handling messages with different levels of security includes examining an attribute of a message received over a network in order to determine a security-related level associated with the message, generating a visual indication for display to a device user that is indicative of the determined security-related level, wherein the generated visual indication is applied to a displayed portion of text associated with the message, and changing the visual indication when the message viewed.

Systems and methods for displaying messages to a user, the messages having different levels of security, are provided herein. One method of displaying to a user messages having different levels of security includes receiving a message over a network includes examining an attribute of the message to determine a security-related level associated with the message. A visual indication for display to a device user is generated by the device. Such visual indication is indicative of the determined security-related level, and is configured to be visible during scrolling through a majority of the message text.
