A machine readable medium carries operating software for use in a system which comprises the programmable device carrying at least one on-device file and/or application and an interface device for interfacing with the or each programmable device. The interface device is provided with at least one one-off device file and/or application; the operating software. The operating software enables, in use, the on-device and off-device files and/or applications to interface with one another and includes at least one file formatted in a web (Internet) standard language for self-describing messages, preferably XML. This file contains at least some of the file system and commands for accessing the file system which allow the on-device and off-device files and/or applications to interface. The interface device may be provided with at least one upgrade file in, for example, XML which contains an upgraded version of at least one on-device file and/or application and includes means for comparing the version of the on-device file or application on a particular programmable device with that in the upgrade file, upgrading the on-device file or application if the version on that device is earlier than that in the upgrade file. The interface device or the programmable device may, further, be provided with a file in web standard language which contains at least one configurable Security Environment. The system or device may include a plurality of files formatted in web standard language for self-describing messages, each of those files including a data model (‘virtual card’) corresponding to one of a plurality of different programmable devices, for example, smart cards of different kinds. The system may include means for configuring at least one of those virtual cards for downloading on to a memory-bearing programmable device. The system may further include at least one file in web standard language for self-describing messages capable of generating at least one APDU which, when run on a smart card, modifies or updates existing files or file structures.
A programmable device carrying a file system and operating software enabling the on-device file system to interface with at least one off-device file and/or application;
A device according to any of claims 1 to 4 comprising a script engine capable of running one or more Application Protocol Data Units (‘APDUs’) loaded from, an interface device to modify the file system, structure and content, or the commands to be used for accessing the file system or any security conditions associated therewith
A device according to claim 5 comprising means for decrypting APDUs loaded from the interface device in encrypted form before they are run by the script engine.
A device according to any preceding claim comprising means for verifying a digital signature before the script engine runs a script loaded from the interface device.
A device according to any preceding claim comprising means for verifying a Retail Message Authentication Code (‘MAC’) before the script engine runs a script loaded from the interface device.
Dependencies are inferred from the claim text.
