Abstract

A system and method implementing secure radio communications in a decentralized network includes: a handshake with one other of the plurality of nodes; establishing a point-in-time reference parameter during the handshake, wherein the point-in-time reference parameter is identified at the end of the handshake with the one other node; identifying a window in randomly sequence of rotating windows based on the point-in-time reference parameter, wherein the identified window contains a channel for conducting an encrypted communication with the one other node; and establishing the communication channel with the one other node.

Claims

A system for secure communications in a decentralized mesh communication network operating without a central authority, the system comprising:
a plurality of nodes, each of the plurality of nodes having, at least:
(i) a communication interface implementing one or more communication protocols for decentralized communication in the mesh network, the one or more communication protocols having strong encryption attributes, and implemented without a central server authority,

(ii) a cryptographic co-processor,

(iii) a cryptographic key storage medium having cryptographic code store thereon, that when executed by the cryptographic co-processor performs:
(a) implement a handshake with one other of the plurality of nodes;

(b) establish a point-in-time reference parameter during the handshake, wherein the point-in-time reference parameter is identified at the end of the handshake with the one other node;

(c) identify a window in randomly sequence of rotating windows based on the point-in-time reference parameter, wherein the identified window contains a channel for conducting an encrypted communication with the one other node; and

(d) establish the communication channel with the one other node.
The system of claim 1, wherein the communication protocol for decentralized communication comprises Telehash and TMesh.
A method for implementing secure and private radio communication between autonomous devices operating in a decentralized network, the method comprising:
at a cryptographic processor of an autonomous device:

implementing a handshake with one other of the plurality of autonomous devices;

establishing a point-in-time reference parameter during the handshake, wherein the point-in-time reference parameter is identified at the end of the handshake with the one other autonomous device;

identifying a window in randomly sequence of rotating windows based on the point-in-time reference parameter, wherein the identified window contains a channel for conducting an encrypted communication with the one other autonomous device; and

establishing the communication channel with the one other autonomous devices.
A non-transitory computer-readable medium comprising computer-executable instructions that when executed by one or more of a processor and a cryptographic processor, causes the one or more of the processor and the cryptographic processor to perform:
implementing a handshake with one other of the plurality of nodes;

establishing a point-in-time reference parameter during the handshake, wherein the point-in-time reference parameter is identified at the end of the handshake with the one other node;

identifying a window in randomly sequence of rotating windows based on the point-in-time reference parameter, wherein the identified window contains a channel for conducting an encrypted communication with the one other node; and

establishing the communication channel with the one other node.
