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

摘要

The present invention relates to a cryptographic key distribution method, a card reader module using the same, an authentication server, and a cryptographic key distribution system. The method includes: receiving institution authentication information and an encryption key including VAN identification information and identification information for a card reader module from a VAN server; Transmitting institution authentication information received from the VAN server to an authentication server; Receiving an authentication result from the server by comparing the institution authentication information transmitted to the authentication server with the institution authentication information stored in the authentication server; And storing the cryptographic key received from the VAN server as the cryptographic key of the institution corresponding to the VAN identification information when the authentication information transmitted to the authentication server is valid.;
