摘要:
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 for processing encoded messages within a wireless communications system are disclosed. A server within the wireless communications system performs signature verification of an encoded message and provides, together with the message, an indication to the mobile device that the message has been verified. In addition, the server provides supplemental information, such as, for example, a hash of the certificate or certificate chain used to verify the message, to the device, to enable the device to perform additional checks on the certificate, such as, for example, validity checks, trust checks, strength checks, or the like.

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 wireless communication system which employs cryptographic functions requiring random data input in a mobile wireless device includes provisions for securely adding randomness to the mobile wireless device. Such added randomness can be securely provided during synchronizing sessions with a device user's base computer via secure wired and/or wireless connections. The new random data can be obtained by software and/or hardware random number generators accessible to the user's base computer and/or from accessible secure external sources (e.g., a secure website source of random data).

摘要:
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 method and system are provided for secure messaging on mobile computing devices. The method and system provide for an indication of a security trust level associated with a security method used with an electronic message.
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 associate with the recipient. The received data is used to perform a validity cheek 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.
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.
