Abstract
A data storage device having a smart card based copy protection function is provided. The data storage device encodes data using the temper resistant key of the smart card as the encoding seed, stores the encoded data, and transmits the encoded data to other device. Therefore, it is impossible to modulate or to make the illegal copy of stored or transmitted data, and the reliability of the storage device can be improved.
Claims13
A data storage device having a smart card based copy protection function comprising:
- an interface for transmitting and receiving data requested to read or write;
- a control unit for controlling transmission and reception of the data through the interface;
- a smart card for providing tamper resistant key information used to encode and decode the data transmitted and received through the interface;
- an encoding chip for encoding or decoding the data transmitted and received through the interface using the tamper resistant key;
- and
- a memory for storing the encoded data.
A data storage device having a smart card based copy protection function comprising:
- an interface for transmitting and receiving data requested to read or write;
- a control unit for controlling transmission and reception of the data through the interface;
- a smart card for encoding or decoding the data transmitted and received through the interface using an internal tamper resistant key;
- and
- a memory for storing the encoded data.
A method of storing data in a data storage device comprising:
- receiving data to be stored;
- acquiring a tamper resistant key of a smart card;
- encoding the received data based on the acquired tamper resistant key;
- and
- storing the encoded data.
A method of storing data in a data storage device comprising:
- acquiring a tamper resistant key of an own smart card when it is requested to transmit data to other storage device;
- reading and decoding the requested data based on the acquired tamper resistant key;
- receiving the tamper resistant key of a smart card in a storage device to transmit the data;
- encoding the decoded data based on the transmitted tamper resistant key;
- and
- transmitting the encoded data to the other storage device.
