Proof-of-work for securing IoT and autonomous systems

DWPI Title: Proof-of-work challenger system for securing IoT and autonomous systems comprises a transmitter configured to transmit transmission data, a receiver is configured to receive reception data, a processor adapted to perform acts
Abstract: A first device in a network issues a proof-of-work challenge to a second device in the network. The second device computes a cryptographic function result to satisfy a criterion indicated in the challenge. The second device returns a challenge response comprising inputs to the cryptographic function that the second device used to compute the cryptographic function result satisfying the criterion. The first device, upon receiving the challenge response, verifies that the inputs to the cryptographic function yield a result satisfying the criterion. Responsive to verifying the challenge response, the first device updates a blockchain based upon the challenge response.
Use: Proof-of-work challenger system for securing IoT and autonomous systems.
Advantage: The system generate and/or verify challenge responses without degrading performance of the individual devices. The systems allow potential attacks to be detected and stopped without requiring encryption of a large amount of communication occurring on the network, hence conserving network bandwidth and computing resources that would otherwise be used for the purposes of encrypting and decrypting network traffic.
Novelty: The proof-of-work challenger system (100) comprises a transmitter configured to transmit transmission data. A receiver is configured to receive reception data. A processor adapted to perform acts. A memory is adapted to store instructions that, when executed by the processor, cause the processor to perform some acts. The acts involves causing the transmitter to transmit transmission data corresponding to a proof-of-work challenge to a proof-of-work challenged system, each proof-of-work challenge being unique, each proof-of-work challenge has a data indicative of an acceptable challenge response. The data indicative of the acceptable challenge response has a result characteristic, and a difficulty of each proof-of-work challenge depending upon the proof-of-work challenged system.
