Method for performing cryptographic operation of smart card for use with e.g. smart phone, involves applying key derivation function to data value and position data by smart card to generate position-dependent first cryptographic key

摘要

The method involves identifying or receiving (202) the first position data from a smart card. The smart card is accessed (204) to a data value stored in a protected memory of the smart card is stored, or input manually by a user of the smart card. The key derivation function is applied (206) to the data value and the first position data by the smart card to generate a position-dependent first cryptographic key. The first position-dependent cryptographic key is used (208) by the chip card to perform implementation of the cryptographic operation. Independent claims are included for the following: (1) a computer program product for performing cryptographic operation; and (2) a smart card.
