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

摘要

The present invention relates to a cryptographic key distribution method, a terminal device using the same, a card reader module, and a cryptographic key distribution system. Receiving public keys for authentication from at least one VAN server from a key distribution server using a distribution public key stored in a card reader module in a terminal device connected to the card reader module; Transmitting the received public key for authentication to the card reader module; Receiving an encryption key from a VAN server using a public key for authentication; And transmitting the received encryption key to the card reader module.;
