Data processing on a non-volatile mass storage device

摘要

A non-volatile mass storage device is provided comprising memory circuitry accessible to a host data processing device via a communication link. The non-volatile mass storage device comprises processing circuitry for locally accessing the memory circuitry of the file system and is capable of triggering generation of a file for storage on the memory circuitry by connection of the non-volatile mass storage device to the host data processing device. The generated file comprises information dependent upon a state of the non-volatile mass storage device. A corresponding method of operating a non-volatile mass storage device is provided and a computer program is provided for obtaining the information dependent upon the state of the non-volatile mass storage device, for locally accessing the memory circuitry and for generating the file for storage on the memory circuitry.

1. A non-volatile mass storage device comprising:
memory circuitry remotely accessible by a host file system of a host data processing device via a communication link; processing circuitry in said non-volatile mass storage device, the processing circuitry being configured to locally access said memory circuitry in said non-volatile mass storage device as a local file system and to generate a file for storage on said memory circuitry; wherein said processing circuitry in said non-volatile mass storage device is configured to be triggered to locally access state information stored on said non-volatile mass storage device, and to dynamically generate said file comprising data derived from said state information, by connection of said non-volatile mass storage device to said host data processing device independent of said host file system of said host data processing device and without any interaction with software executed on said host data processing device, and wherein said state information comprises a combination of a serial number of said non-volatile mass storage device and a secret key generated using a hash function.
