摘要:
If a smart card is to be used for a particular purpose, and there is no certificate initialized on the smart card for this purpose, a computerized device enables a user to select one of the certificates already installed in the smart card for the particular purpose. The selected certificate may be imported into the computerized 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 wireless-enabled smart card reader receives an Answer to Reset (ATR) from a smart card and transmits the ATR using a wireless communication link to a computing device without waiting for an ATR request from the computing device. The computing device may cache the ATR and use it for subsequent communication sessions with the smart card.
摘要:
A mobile communications device, method, and computer program product for providing security on a mobile communications device are described. In accordance with one example embodiment, the mobile communications device comprises: a processor; a communications subsystem connected to the processor operable to exchange signals with a wireless network and with the processor; a storage element connected to the processor and having a plurality of application modules and data stored thereon, the data comprising at least user application data associated with the application modules and service data including data for establishing communications with the wireless network; and a security module operable to determine if a battery level falls below a predetermined threshold and perform a security action comprising erasing or encrypting at least some of the data on the storage element if the battery power falls below the predetermined threshold.
摘要:
A system comprises a wireless-enabled device that communicates with a wireless-enabled smart card reader to obtain information from or perform operations using a smart card. Commands to access information from a smart card may be sent from the device to the smart card reader, and responses from the smart card may be sent from the smart card reader back to the second device. Communication between the device and the smart card reader via a wireless communication link is slower than communication via a direct link. Communication of two or more commands and/or responses via the wireless communication link may be made more efficient by grouping the commands or responses together in groups.
摘要:
A method is presented to allow pairing of a first wireless-enabled device to a second wireless-enabled device while the first device is locked. A pairing interface is provided on the locked first device to obtain pairing information about the second device. The pairing information is used to pair the first device to the second device and to establish wireless communications therebetween without first requiring that the first device be unlocked.
摘要:
A system and method for providing an indication of randomness quality of random number data generated by a random data service. The random data service may provide random number data to one or more applications adapted to generate key pairs used in code signing applications, for example. In one aspect, the method comprises the steps of: retrieving random number data from the random data service; applying one or more randomness tests to the retrieved random number data to compute at least one indicator of the randomness quality of the random number data; associating the at least one indicator with at least one state represented by a color; and displaying the color associated with the at least one indicator to a user. The color may be displayed in a traffic light icon, for example.
摘要:
A wireless device may alert a wireless smart card reader that communication of data between the wireless device and the wireless smart card reader is probably imminent by sending an activation alert. Upon receipt of the activation alert, if the wireless smart card reader is in a low-power state, the wireless smart card reader may enter a higher-power state. If the wireless smart card reader is in the higher-power state upon receipt of the activation alert, the wireless smart card reader may remain in the higher-power state until a timeout period has expired. The wireless device may instruct the wireless smart card reader to enter the low-power state by sending a deactivation alert if the wireless device identifies that communication of data between the wireless device and the wireless smart card reader is not likely to occur within a specified period of time.
摘要:
A system and method for providing secure message signature status and trust status indications are disclosed. When a secure message having a digital signature generated by a sender is selected for processing on a messaging client, the digital signature on the message and trust status of the sender are checked. Separate indications are then provided to indicate the results of checking the digital signature and the trust status of the sender.
摘要:
An active new password entry dialog provides a compact visual indication of adherence to password policies. A visual indication of progress towards meeting all applicable password policies is included in the display and updated as new password characters are being entered. A visual hint associated with at least one applicable password policy that has not yet been satisfied is also included in the display. An ability to obtain more detailed comprehensive password policy information is also permitted upon user command (e.g., including an indication whether each password policy has yet been met or unmet). Preferably the displayed hint and associated applicable password policy not yet satisfied is randomly changed during entry of a new password (e.g., upon the entry of each new password character).
