Abstract

The invention provides a method for safe downloading of a TMK. The method comprises the steps that a TK is generated by a POS terminal; the TK is collected by an operation terminal and uploaded to an MTMS; the TK is managed by the MTMS in a unified mode and transmitted to a corresponding KMS; remote downloading of the TMK is started by the POS terminal; bidirectional authentication is conducted on the POS terminal and the KMS through an AUK and after authentication, the TMK is transmitted to the POS terminal through the KMS. The method has the advantages that the TK is uploaded by the POS terminal so that the TMK can be remotely downloaded; by the adoption of the MTMS, management and uploading of the TK is greatly facilitated; it is guaranteed that the TK is transmitted to the corresponding KMS. Bidirectional authentication is further conducted between the POS terminal and the KMS before master key transmission is conducted, and the downloading safety of a master key is further improved.

Description

technical field [0001] The invention relates to the field of electronic payment, in particular to a method and system for safely downloading a terminal master key TMK. Background technique [0002] Bank card (BANK Card) is becoming more and more popular as a payment tool. Common bank card payment systems include point of sale terminals (Point Of Sale, POS), POS acquiring system (POSP), password keyboard (PIN PAD) and hardware encryption machine (Hardware and Security Module, HSM). Among them, the POS terminal can accept bank card information, has communication function, and accepts the instructions of the teller to complete the financial transaction information and related information exchange equipment; the POS acquiring system centrally manages the POS terminal, including parameter download, key download, acceptance, It is a centralized management and transaction processing system that processes or forwards transaction requests from POS terminals and returns transaction r...
