摘要:
In one embodiment, there is provided a mobile communications device comprising: a processor; a communications subsystem operable to exchange signals with a wireless network; a storage element having 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 detect policy messages received by the device, and to perform a security action if a first policy message to enforce a first data protection policy is received and a subsequent policy message to enforce a second data protection policy is not received within a predetermined duration from the time at which the first policy message is received; wherein the security action comprises erasing or encrypting at least some of the data on the storage element.
摘要:
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 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 the creation and automated selection and inclusion an automated signature text with an electronic message, wherein the automated selection of the automated signature text is dependent on attributes of the message, the designated recipients, or attributes of the designated recipients as compared to the sender's attributes, such as the encoding type and/or transport method selected for the electronic message or the location of the recipient without the need for multiple user profiles or manual editing by the sender. At least one of a plurality of automated signature texts is associated with at least one encoding type of a plurality of encoding types, at least one message transport type, or with at least one predeterined recipient attribute or the outcome of a comparison of the recipient attribute with the sender's attributes. The appropriate automated signature text is inserted prior to encoding of the message for transport.
摘要:
Enhanced reset logic is included in a user's computerized device so that the device owner (e.g., the user's employer) can assure prompt reset (e.g., to insure device use of newly downloaded software versions or other control or security data) while still allowing user convenience (e.g., some limited continued normal use of the device before reset is forced upon the user thus permitting the user to avoid possibly aggravating losses of data and/or ongoing usage).
摘要:
Systems and methods for managing data transfers between a secure location and a less secure location. A data transfer checker operating on a mobile device determines whether an attempted data transfer between two locations is permitted. If it is not permitted, then the data transfer is prevented and the user may be notified of the data transfer prevention.
摘要:
A method and system for performing garbage collection involving sensitive information on a mobile device. Secure information is received at a mobile device over a wireless network. The sensitive information is extracted from the secure information. A software program operating on the mobile device uses an object to access the sensitive information. Secure garbage collection is performed upon the object after the object becomes unreachable.
