Abstract
Example embodiments of present invention disclosed herein are directed to an IC chip card capable of detecting an external attack on data of a memory device. An IC chip card may include a memory device adapted to store data including a stored integrity identification value, an integrity identification value generating unit adapted to calculate an integrity identification value of the data, and a microprocessor adapted to compare the stored integrity identification value with the calculated integrity identification value to determine whether the data of the memory device has been compromised.
Claims15
An IC chip card comprising:
- a memory device adapted to store data including a stored integrity identification value;
- an integrity identification value generating unit adapted to calculate an integrity identification value of the data;
- and
- a processor adapted to compare the stored integrity identification value with the calculated integrity identification value to determine whether the data of the memory device has been compromised.
A method of detecting whether data of a memory device in an IC chip card has been compromised, comprising:
- receiving a stored integrity identification value output from the memory device;
- calculating an integrity identification value for the data of the memory device;
- and
- comparing the calculated integrity identification value with the stored integrity identification value to determine whether the data of the memory device has been compromised.
