Electric power RPL protocol black hole attack defense method based on cuckoo filter

Abstract

The invention discloses an electric power RPL protocol black hole attack defense method based on a cuckoo filter, and belongs to the field of intelligent power grid safety. The method comprises the following steps: firstly, creating a credible node hash table based on a cuckoo filter, wherein the credible node hash table comprises all legal members of an AMI network; and when the DODAG is constructed for the first time, transmitting the trusted device list to each trusted device. When RPL is used for dynamic DODAG construction, by modifying selectable fields of DIO control information and DAOcontrol information in an RPL control message, when equipment network topology changes, equipment identity authentication is carried out, and therefore possible RPL black hole attacks are detected; bypreventing DIO messages sent by malicious nodes, the AMI network can be protected against black hole attacks. Compared with an existing attack detection method, the method is wider in defense range and more effective.

AI Technical Summary

Benefits of technology

This patented technology optimizes an algorithm called RPL that allows any device connected into your network (called client) to be identified by its IP address or other identifiers like MAC addresses). It also includes various mechanisms such as establishing a strong connection between two servers before sending data packets over them. By adding these features to the ID-based authorization used during startup phases, it becomes better at preventing denials from hackers trying to compromise systems' integrity without being detected. Overall, this innovative approach helps improve communication networks while protecting their sensitive equipment.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing an improved system for managing power usage within electronic grids like smart grids without compromizing their reliability due to poor signal quality caused by lower levels of noise during transmission compared with older systems based on wired connections.
