Embodiment

[0032] 1) Two-way identity authentication between the on-site service terminal and the electronic seal.

[0033] The on-site service terminal sends an authentication command;

[0034] The electronic seal returns a random number R1: 97273832;

[0035] The security unit encrypts the random number R1 to obtain E R1 : E697B749;

[0036] The field service terminal will E R1 : E697B749 and random number R2: 07766126;

[0037] Electronic seal decryption E R1 : E697B749 got R1`: 97273832, R1 and R1` equal authentication passed. Encrypted random number R2: 07766126 to get E R2 :ED5BECF7;

[0038] Field service terminal decryption E R2 : ED5BECF7 got R2`: 07766126, R2 and R2` passed the certification.

[0039] 2) The on-site service terminal reads the electronic seal information.

[0040] The field service terminal sends the command to read the electronic seal information: E80807141634490004001897273832ED5B EC F707766126E697B749627F DC21AE3B2E5C DF E7;

Abstract

The invention relates to a field encrypting and sealing method based on a field service terminal. The method comprises the steps of (1) downloading field data to be sealed, (2) carrying out bidirectional identity authentication with an electronic seal, (3) reading encrypted messages of information of the electronic seal, (4) carrying out decryption to obtain the sealed information and storing and displaying the sealed information, (5) carrying out encryption to obtain messages of the data to be sealed, and (6) carrying out filed sealing. According to the field encrypting and sealing method based on the field service terminal, a safety unit of the field service terminal is used for encrypting the data to be sealed and decrypting the data in the electronic sealing, and a radio frequency read-write unit of an RFID is used for carrying out sealing and sealing changing on field electric energy meters. Therefore, safety is ensured, and working efficiency is improved greatly. The safety unit inside the field service terminal is used for carrying out encryption and decryption operation and integrity checking on the data of the electronic seal, a cryptographic machine does not need to be connected remotely, and operation speed is high. When communication is carried out between the field service terminal and the electronic seal, the data are all transmitted in an encrypted message mode, therefore, safety and reliability are achieved, and requirements for confidentiality, integrity and repudiation prevention can be met.

Description

technical field [0001] The invention belongs to a power system, and in particular relates to an on-site sealing method based on an on-site service terminal. Background technique [0002] The field service terminal is a kind of application of cryptographic technology to realize data exchange with smart energy meters, collection terminals, electronic seals and other equipment, and to realize security authentication, meter reading, parameter setting, emergency closing, key downloading and asset management and other operations. Portable handheld device. The electronic seal is a seal that uses a built-in RFID radio frequency tag (electronic tag) as the information carrier, and the seal information is stored in the RFID electronic chip. At present, the State Grid Corporation is gradually replacing the old-fashioned lead seals of electric energy meters with electronic seals to meet the requirements of assembly line detection and information management. Compared with the old-fashi...
