Long-distance encryption method and device, management method and device, as well as encryption management method and device

Abstract

The invention provides a long-distance encryption method and device, a management method and device, as well as an encryption management method and device. The encryption method comprises the following steps: a POS (point of sales) terminal sends a request massage to a TMS (terminal management system), receives a response authentication request massage sent by the TMS, calculates according to the terminal authenticating data plaintext, downloading work key ciphertext and downloading maintaining secret key to obtain the second terminal authentication ciphertext, and judges whether the second terminal authentication ciphertext is the same as the first terminal authentication ciphertext, and if the authentication ciphertexts are the same, the TMS authentication ciphertext is encrypted to obtain the TMS authentication ciphertext; and the POS terminal sends the responding authentication massage to the TMS, and receives the secret key plaintext comprising secret key ciphertext sent by the TMS. In the invention, the problem that the long-distance terminal maintenance management TMS can not remotely manage and maintain all the POS terminals is solved, thereby reducing the cost for maintaining the POS terminal and improving the satisfaction degree of users.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a remote encryption method, a remote management method, a remote encryption management method, a remote encryption device, a remote management device, an encryption management device and a system. Background technique [0002] With the continuous improvement of industrial automation level, more and more system terminal devices need to use the software download function, such as bank card machines (POS, Point Of Sales), terminal remote maintenance management system (TMS, Temfinal Management System), etc. The characteristics of the system require their program functions to be continuously improved, enriched and upgraded, or updated according to changes in user needs. However, with the continuous increase in the number of POS terminals, moreover, there are many types of POS terminals, and there are many corresponding application program versions; . Therefore, the unified...
