Embodiment Construction

[0041] At present, the process layer communication technology based on the IEC 61850 standard is widely used in the digital substation system, which greatly improves the interoperability between the equipment in the substation; however, the process layer communication in the IEC 61850 standard does not include security measures. There are security risks in the standard transmission of data. Aiming at the information security issues of digital substations, the International Electrotechnical Commission issued the IEC 62351 standard.

[0042] Among them, the IEC61850 series standards are substation network communication standards, which regulate the communication behavior and system requirements between intelligent electronic devices (Intelligent Electronic Devices, IEDs) in substations. The process layer refers to the intelligent equipment in the digital substation. The process layer is mainly used to complete the real-time electrical quantity detection of power operation, the s...

Abstract

The invention discloses a message anti-replay method and electronic equipment, and the method comprises the steps: starting a first timer when the restart is completed, wherein the overtime of the first timer is greater than or equal to the maximum effective duration of a message; receiving a message; and under the condition that the first timer is not overtime, discarding the first message.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message anti-replay method and electronic equipment. Background technique [0002] At present, the electronic equipment in the digital substation system usually transmits messages based on the IEC 62351 standard. After the electronic equipment is restarted, the replayed message will be received by mistake. A replay message refers to a message that has already been received by the receiver. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide a message anti-replay method and electronic equipment, so as to solve the problem in the related art that the receiver may mistakenly receive replayed messages when restarting. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] An embodiment of the present invention provides a message anti-replay met...
