Title: Method and system for authentication of electronic communications

Abstract

A method and system to authenticate electronic communications, such as email. A trusted third party records information of each of sender's communications, such as date, time and recipients. Recipients are allowed to verify if their incoming messages match the data of their senders' outgoing communications. Mismatches can be used to filter out fake messages assuming stolen identities.

Communication systems and methods for authenticating data packets within network flow

Patent Bush, Stephen Francis

A communication system includes a first quantum key distribution device and an intermediary device. The first quantum key distribution device is configured to be coupled to a second quantum key distribution device over a quantum channel and to generate a shared key with the second quantum key distribution device based on a quantum state transmitted along the quantum channel. The intermediary device is disposed along a communication pathway within a network between a sender device and a receiver device. The intermediary device is communicatively connected to the first quantum key distribution device and configured to utilize the shared key tomore » « less

Physical layer authentication of electronic communication networks

Patent Suski, William Charles; Card, Christopher Alan; Few, Brian Richard

A network authentication system can be configured for sampling a plurality of signal samples from a device on a network, providing the plurality of signal samples to a first machine-learned model that is configured to determine a device fingerprint based at least in part on the plurality of signal samples, and providing the device fingerprint to a second machine-learned model that is configured to classify the device based at least in part on the device fingerprint.

Systems and methods for electronic communication with a device using an unknown communications protocol

Patent Patel, Silpan M.; Knee, Peter A.

Various technologies for communicating with systems that communicate using an unknown communications protocol are described herein. A transceiver intercepts a plurality of communications exchanged between two or more transceivers on a communications network. Pattern-recognition algorithms are executed over the plurality of communications, and features of an unknown communications protocol that governs the communications between the two or more transceivers are inferred based upon output of the pattern-recognition algorithms. A communication is formatted based upon the inferred features of the unknown communications protocol, and the communication transmitted to one or more systems on the communications network by way of the transceiver.more » « less

Non-intrusive data authentication systems and methods

Patent Thomas, Maikael A.; Hymel, Ross W.; Baldwin, George T.

Systems and methods are disclosed that create a separate digital and cryptographically secure signal “branch” to a secondary observer from a primary signal path of an information system. The information system may be a measurement system. The secure signal branch is creating without interfering with the primary signal path. In such a manner, the secondary observer may authenticate reported data while not interfering with the signal of the information system.

System and method for authentication

Patent Duerksen, Gary L.; Miller, Seth A.

Described are methods and systems for determining authenticity. For example, the method may include providing an object of authentication, capturing characteristic data from the object of authentication, deriving authentication data from the characteristic data of the object of authentication, and comparing the authentication data with an electronic database comprising reference authentication data to provide an authenticity score for the object of authentication. The reference authentication data may correspond to one or more reference objects of authentication other than the object of authentication.
