AI Technical Summary
Existing electric power transmission and distribution systems face challenges in ensuring secure access to intelligent electronic devices (IEDs) due to the risk of unauthorized access, which can compromise the system if a single user is compromised, leading to potential corruption or malicious attacks.
A token-based access control system that requires two-party authorization, where a supervising user approves the token grant for a second user, ensuring that both users possess a token to access IED resources, with each access request being logged and recorded to enhance traceability and accountability.
This system significantly reduces the likelihood of unauthorized access and inside attacks by requiring dual authorization, increasing the security and traceability of engineering access to IEDs, thereby protecting the integrity of the power transmission and distribution system.
