Abstract
Improved optical network security (e.g., using a computerized tool) is enabled. Various embodiments herein can send (e.g., via a network) to a group of network devices comprising a first network device and a second network device, a first encrypted data stream, a second encrypted data stream, a first hash code, and a second hash code, wherein the first network device deletes the second encrypted data stream after the first network device hashes the second encrypted data stream, and in response to the second network device being determined not to have received the second hash code within a defined threshold time, determine that the first network device is unauthorized to use the network.
