METHOD FOR DISTRIBUTING ENCRYPT KEY CARD READER AND SYSTEM FOR DISTRIBUTING ENCRYPT KEY THEREOF

摘要

The present invention relates to a cipher key distribution method, a card reader module using the same, and a cipher key distribution system. The method includes generating institutional authentication information including identification information of a VAN and identification information of a card reader module to be used in a card reader module; Transmitting the generated organization authentication information to an authentication server; Receiving institution authentication information and an encryption key from a VAN server; Comparing the institution authentication information received from the VAN server with the generated institution authentication information; And storing the received encryption key as an encryption key for the VAN server when the authentication result information received from the VAN server is valid.;
