摘要:
The described embodiments relate generally to devices, methods and systems for managing access to a memory card, such as a smart card, by a plurality of accessing devices. Certain embodiments relate to a smart card reader for managing concurrent access to a smart card, wherein when a channel manager receives a close session request from a first accessing device, and a first session is open on a first channel for the first accessing device and a second session is open on a second channel for a second accessing device, the channel manager is configured to: issue a close channel command to the smart card to close the second channel; issue the close session request from the first accessing device to the smart card; and issue a further session request to the smart card to re-open the first channel, and continue the second session on the re-opened first channel.

The described embodiments relate generally to devices, methods and systems for managing access to a memory card, such as a smart card, by a plurality of accessing devices. Certain embodiments relate to a smart card reader (SCR) for managing concurrent access to a smart card by a plurality of accessing devices, the SCR comprising: a processor; a channel manager responsive to the processor for interfacing with the smart card; a communication interface responsive to the channel manager for communicating with the plurality of accessing devices; and wherein, when a session is open on a first channel between a first accessing device and the smart card and the channel manager is configured to issue an open channel command to the smart card to cause the smart card to open a second channel between the smart card and the second accessing device in response to the session request.

A method for dynamically (i.e., upon boot) rewriting, in a failure resistant manner, of part of, or the entirety of, the flash memory for a device allows for a changing of location for logical blocks of execute-in-place code. Conveniently, the rewriting results in a randomization, of varying degree, of the address space layout upon each boot up cycle.

A communication device is configured to receive messages. The communication device may comprise a display screen upon which messages are displayed. A microprocessor configured to execute at least one message management program on the communication device, filters incoming messages. The message management program comprising a message filter application filters received messages based on a comparison of sender identification data associated with a received message to approved sender identification data.
