  • Abstract
    The wide-area primary and backup protection system needs available communication networks to trip relays via remote control, which is vulnerable to cybersecurity threats. This letter proposes a key graph-based key-management framework to secure the communications of wide-area primary and backup protection. Besides, the rekeying strategies are designed to deal with the redirection of communication associations due to the variation of protection zones.
