Opening a port on the internet typically involves signaling a request for consent to consider whether a random incoming connection is good enough to continue. Denial-of-Service (DoS) and Distributed DoS (DDoS) attacks can exploit this process by spamming connection attempts. However, in order to be a service the host and port are to be advertised to the network that is to be connected and (at least in Internet Protocol version 4 (IPv4)) sweeping all open ports in a likely range is a perfectly feasible option. Presented herein are techniques that utilize a novel frequency-hopping approach to listening ports in order to implement consent-based networking.
