Abstract
A system for continuous authentication of internet of things (IoT) devices in a communication network utilizes lightweight authentication for a sequence of message transmissions in a specific time-frame. A claimer device and a verifier device are in communication with the network. The claimer is configured to define a time frame and a time flag for an authentication session for a predetermined maximum number of messages, generate a time-bound share from a secret key, calculate a share authenticator for the share, combine a claimer identity (ID), a verifier ID, a message payload, the share, the share authenticator, a time flag, a timestamp, and message authenticator into a message, and send the message to the verifier within the time period. The verifier is configured to receive the message from the claimer, verify the message freshness, verify authenticity of the time flag and timestamp, and reveal and check the authenticity of the share.
