Embodiment

[0032] 1) Identity authentication between the on-site service terminal and the management system

[0033] Field service terminal operator card production random number R1: 89C4F2E6E5623280;

[0034] The management system encrypts the random number R1 to obtain the ciphertext E R1 : DF266289D5A1D992 and generate random number R2: 582904CB5EC48037;

[0035] Field Service Terminal Operator Card Decryption E R1 Get R1`: 89C4F2E6E5623280, compare R1 and R1`, if they are equal, the identity authentication is passed. And encrypt the random number R2 to get the ciphertext E R21 : F2EF1AB0E5860B2A;

[0036] Management system decryption E R2 Get R2`: 582904CB5EC48037, compare R2 and R2`, if they are equal, the identity authentication is passed.

[0037] 2) The on-site service terminal management module has the authority to open the business module

[0038] The business module sends the random number R1: BCFB91431CABE3AD to the management module;

[0039] The management module se...

Abstract

The invention relates to a field service terminal permission management system and a method thereof. The system comprises a management module and a service module, the management module is connected with a backstage management system and opens permissions of the service module, and the service module is connected with an electric energy meter. The method comprises a first step of enabling the management module and the backstage management system to perform identity authentication, a second step of enabling the management module to open the permissions of the service module, a third step of enabling the service module and the intelligent electric energy meter to perform identity authentication, and a fourth step of calculating plaintext and media access control (MAC) or ciphertext and MAC required for operations such as recharge, control and parameter setting. An operator card and a service card are utilized to manage permissions of a field service terminal, and assignment of responsibilities is clear. An intelligent central processing unit (CPU) card having safety control is used to manage the permissions, the responsibilities are assigned to the two cards, and safety is high. Data processed through the operator card and the service card have the advantages of authenticity, integrity and denial resistance and the like.

Description

technical field [0001] The invention belongs to an electric power system, and in particular relates to a field service terminal authority management system and a method thereof. Background technique [0002] The field service terminal is a portable handheld device that uses cryptographic technology to exchange data with smart energy meters, collection terminals and other equipment, and realizes security authentication, data collection, parameter setting, emergency closing and asset management. A security unit is installed in the field service terminal. The security unit is an embedded module that completes key storage and encryption and decryption process control. It is equipped with an operator card and a business card. When the field service terminal communicates with the master station, electric energy meter, and collection terminal, Complete identity authentication and data encryption / decryption operations. The operator card is a smart card used to identify and determin...
