Latest Patents

One of his latest patents is titled "Response-based cryptography using physical unclonable functions." This invention discloses systems and methods for authentication and encrypted communication between a server and client devices using independently-generated shared encryption keys. In this system, client devices equipped with arrays of physical unclonable function devices respond to challenges issued by a server. The server stores characteristics of these arrays during a secure enrollment process and subsequently issues challenges to the clients. The clients derive encryption keys from their responses to these challenges, allowing them to send encrypted messages to the server. The server can independently reproduce the client-generated encryption key, enabling secure communication without the need to exchange encryption keys. Ternary PUF characterization schemes may be utilized to achieve acceptable authentication error rates.

Another notable patent by Booher is for the "Generation of composite private keys." This invention provides a system and method for generating composite private keys by retrieving first and second bitstreams from an addressable cryptographic table. The process involves deriving addresses from an initial instruction, accessing stored bit values, and forming a data stream and a selector stream. A first composite encryption key is then created by selecting values from the data stream based on the corresponding bit values of the selector stream.
