Title: Innovations by Zdenek Paral in Authentication Technologies

Introduction

Zdenek Paral is an accomplished inventor based in San Jose, CA. He has made significant contributions to the field of authentication technologies, holding 2 patents that showcase his innovative approach to security.

Latest Patents

One of his latest patents focuses on "Authentication with Physical Unclonable Functions." This technology allows for the implementation of Physical Unclonable Functions (PUFs) in various electronic devices, including FPGAs, RFIDs, and ASICs. The system utilizes challenge-response pairs corresponding to individual PUFs, which can be enrolled and used to determine authentication data managed in a database. When a target object with a PUF is authenticated, a set of challenges is applied to each PUF device, distinguishing it from others. Notably, this method achieves authentication without the need for complex cryptographic circuitry on the device, and an authentication station does not need to communicate with an authority holding the authentication data during the process.

Another significant patent by Zdenek Paral is "Soft Message Signing." This innovation allows a message to be signed using a PUF without the necessity of regenerating a cryptographic key exactly. A recipient who shares information about the PUF can verify the signature with high accuracy, ensuring a low probability of false rejections of true signatures and a high probability of rejecting forged signatures. The information shared may include a parametric model of the operational characteristics of the PUF used for the signature.
