Abstract
Systems, methods, and devices are described herein for executing a lockdown of electronic locks deployed in a local network of interconnected devices. In example implementations, each electronic lock is provided with a unique encryption key specific to that electronic lock and is provided with a shared encryption key. To execute a lockdown of all electronic locks in the local network, a server generates a locking instruction and encrypts it using the shared encryption key. The server then transmits the encrypted locking instruction to the gateway devices of the local network which, in turn, transmit it to each of the electronic locks. Upon receipt of the encrypted locking instruction, the electronic locks attempt to decrypt it using the shared encryption key. Upon successful decryption of the encrypted locking instruction, an electronic lock toggles to a lock state.
