摘要:
Systems and methods for secure e-mail message processing. A device is configured to receive a secure electronic message. The message may then be processed to determine whether the sender's address provided in the message is indicative of the sender's address provided in a sender's security-related certificate. A message's recipient can be notified based upon the determination.
摘要:
A system and method for processing messages with encryptable message parts. When constructing an encoded message, an encryption key of a plurality of identified encryption keys is used to encrypt message data of a message part. A key identifier is associated with the message part and identifies the encryption key used for the encryption of the message data of the message part. In at least one exemplary embodiment, encryption keys that are used to encrypt message data of message parts are provided in a separate message part, arranged by key identifier. In particular, the encryption keys, arranged by key identifier, may be provided in exactly one message part separate from the message parts containing message data. This allows for a compact message encoding.

Systems and methods for establishing a security-related mode of operation for computing devices. A policy data store contains security mode configuration data related to the computing devices. Security mode configuration data is used in establishing a security-related mode of operation for the computing devices.

A wireless communication device (and its related method of operation) includes, if invoked, password protected access to data stored therewithin and/or to normal device operations and further includes duress password checking logic that automatically causes a duress message to be sent if a duress password has been entered. The duress message is preferably sent without maintaining any user accessible indication of such sending. It is also preferred that the password checking logic automatically cause an end-of-duress message to be sent if a normal password is entered after a duress password has been entered. A plurality of different duress passwords may be entered into a duress password portion of data memory in the device.

A wireless device in a discoverable mode controls its visibility by determining whether to ignore or respond to an inquiry, received from an inquiring device, based at least in part on one or more properties of the inquiring device.
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.
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:
A system and method for determining a security encoding to be applied to a message being sent by a user of a computing device, such as a mobile device, for example. In one broad aspect, the method comprises determining, at the computing device, whether a general message encoding configuration setting thereon indicates that the security encoding to be applied to the message is to be established by a policy engine; if the general message encoding configuration setting on the computing device indicates that the security encoding to be applied to the message is to be established by the policy engine, determining the security encoding to be applied to the message by querying the policy engine for the security encoding to be applied to the message; applying the determined security encoding to the message; and transmitting the message to which the security encoding has been applied to the at least one recipient. In one embodiment, the policy engine is a PGP Universal Server.

摘要:
A method and system for providing e-mail messages to a receiving e-mail application. The e-mail messages as sent from a sending e-mail application being secure and in opaque signed format. The opaque signed e-mail messages being converted to clear signed e-mail messages by decoding extracting message content and digital signatures. The clear signed e-mails being sent to a receiving e-mail application.
