SMART CARD CHIP FOR GENERATING PRIVATE KEY AND PUBLIC KEY PAIR, AND GENERATION METHOD THEREFOR

摘要

The smart card chip for generating a private key and public key pair in accordance with an embodiment of the present invention comprises: a communication unit for performing at least one of a contact communication with an external device and a near-field wireless communication therewith; a control unit for communicating with the external device through the communication unit and generating a private key and public key pair; and a memory unit for storing the generated private key and public key pair, wherein if receiving a command to generate a private key and public key pair from the external device, the control unit checks if a pre-generated private key and public key pair is stored in the memory unit, and if the pre-generated private key and public key pair is stored in the memory unit, the control unit reads the pre-generated private key and public key pair.
