    abstract =  {This document introduces the KeyState EDNS(0) option code, to enable the exchange of SIG(0) key state information between DNS entities via the DNS protocol. The KeyState option allows DNS clients and servers to include key state data in both queries and responses, facilitating mutual awareness of SIG(0) key status between child and parent zones. This mechanism addresses the challenges of maintaining synchronization of SIG(0) keys used for securing DNS UPDATE messages, thereby enhancing the efficiency and reliability of DNS operations that require coordinated key management. This document proposes such a mechanism.
