Castle Shield Holdings, LLC Announces Research Development Partnership with Northern Arizona University | News


Castle Shield, a leading provider of applications and services based on a Zero Trust Architecture framework, today announces a research collaboration with Northern Arizona University (NAU), which aims to develop new approaches to identify, authenticate and protect devices for businesses and consumers. As part of this partnership, Castle Shield and NAU have signed a license agreement which covers the commercialization of licensed products and grants exclusive patent rights to products created under a sponsored research agreement using 12 existing patents and 8 patents pending. Patent rights are granted for all new patents created under a sponsored research agreement until such patents are exhausted.

The research collaboration will be led by Dr. Bertrand Cambou, who joined NAU’s School of Computing, Computing and Cybersystems in 2015, and the Cybersecurity Research Team, recognized for its track record in of innovation. The School of Computing, Computing, and Cybersystems engages in a wide range of collaborative research projects with both commercial and federal industrial partners. The research of the NAU Cybersecurity Team in nanoelectronics and cybersecurity is well supported in the University’s multidisciplinary approach.

The collaboration between Castle Shield and Northern Arizona University will focus on the following high-level areas:

  • Securing encryption keys and devices using a tamper-proof token
  • Added biometrics to the tamper-proof token in later phases of the project
  • Applying secure encryption key and device protection to other devices using nanotechnology, such as Memristors and ReRAM
  • Added support for Quantum Key Distribution (QKD) to Castle Shield’s existing crypto wallet

The first collaborative project will be the co-development of a tamper-proof token that includes the following:

  1. An addressable PUF (Physically Unclonable Function) generator with ternary states,
  2. A ternary addressable public key infrastructure schema,
  3. A response-based cryptography (RBC) engine for error correction, and
  4. A tamper-proof key recovery protocol with a token.
  5. Motherboard/daughterboard tamper key recovery scheme

The first deliverables are an end-to-end solution that provides a quench resistance key recovery protocol embedded in an SRAM-based USB token, and the other provides the identical solution embedded in end-customer motherboards of Castle Shield or added to customer hardware. as a daughter card.

“Castle Shield’s proactive approach to cybersecurity, coupled with its strategic drive to integrate innovative encryption advancements into commercial products such as Post-Quantum Cryptography (PQC), provides my team and I -even a marketing channel for our innovations. Castle Shield is at the forefront of researching and implementing solutions to protect customer information today and minimize attacks tomorrow. Our research, led by a team of PhDs and Northern Arizona University has a similar goal, and together with Castle Shield, we will form a powerful partnership to help businesses and individuals proactively strengthen their cybersecurity posture,” said Cambou. , professor of nanotechnology and cybersecurity. north of Arizona. “At NAU, the cybersecurity team generated 65 invention disclosures and filed 60 patent applications, 35 of which were granted.”

Castle Shield provides partners and customers with advanced solutions that protect their most valuable asset: their data. “We have implemented Post-Quantum Cryptography (PQC) algorithms into our existing Fides product family that are commercially available today; our symmetric and asymmetric encryption solutions are cipher-agnostic, allowing Castle Shield to deliver best-in-class crypto-agility for today and tomorrow,” said Castle CTO Dr. Milton Mattox Shield. “Our collaboration with Northern Arizona University continues our ambitious goal of advancing research innovation with one of the nation’s most prolific inventors in nanoelectronics and cybersecurity. Castle Shield’s mission is to provide industry-leading cybersecurity solutions to protect the nation’s most valuable asset: its data.
