Castle Shield Holdings, LLC Updates the Post-Quantum Cryptography (PQC) Algorithms for Its Data-in-Motion Aeolus VPN Solution

SCOTTSVILLE, Va.–(BUSINESS WIRE)–Castle Shield Holdings, LLC., a leader in Zero Trust and cybersecurity solutions, today announced that its Aeolus VPN solution now supports additional post-quantum cryptography (PQC) algorithms selected by the National Institute of Standards and Technology (NIST).

Last year, prior to the conclusion of the third round of the NIST PQC Standardization, we announced the successful integration of the Saber algorithm into Aeolus VPN. Reference our October 11, 2021, press release.

NIST has now selected two primary PQC algorithms for most use cases: CRYSTALS-KYBER and CRYSTALS-Dilithium. In addition, the signature schemes FALCON and SPHINCS+ were standardized as well. Kyber and Dilithium were both selected for their strong security and excellent performance, and NIST expects them to work well in most applications. Therefore, we have integrated Kyber (i.e., Kyber1024) and Dilithium (i.e., Dilithium5) algorithms into Aeolus VPN as well.

Aeolus VPN protects data between two or more network points. It offers a streamlined approach to privacy which results in more stability and lower latency that is a perfect addition to enterprise data-in-motion security for both classic and post-quantum computing environments. Aeolus VPN offers point-to-point asymmetric PQC and symmetric encryption for UDP and TCP on Windows, Linux, and macOS platforms.

“At Castle Shield, we are encryption agnostic. As NIST selects new PQC standards, we will add them to our suite of solutions that further demonstrates the cryptographic agility of our products. Our primary focus is to seamlessly integrate the best encryption algorithms available with our solutions to protect our customers’ data for today and tomorrow,” said Dr. Milton Mattox, Chief Technology Officer at Castle Shield, Holdings, LLC.

Aeolus VPN with PQC continues to be available today for testing, proofs of concept, and production installations.
