Quantum Xchange and Thales offer quantum-resistant network security to protect data

Quantum Xchange has collaborated with Thales to offer immediate quantum and crypto-agile key delivery capabilities. The resulting quantum-resistant network solution enables end users to future-proof the security of their data and communication networks; overcoming vulnerabilities in current encryption techniques, for example, keys and data traveling together; and protect against the man-in-the-middle, the harvest, and future quantum attacks.

Quantum Xchange’s revolutionary out-of-band symmetric key delivery system, Phio Trusted Xchange (TX), is a simple architecture overlay that works in tandem with conventional cryptosystems, in this case Thales High Speed ​​Encryptors ( HSE), and any TCP/IP connection (wireless, copper, satellite, fiber) to decouple key generation and delivery from data transmissions.

With Phio TX, a second quantum-enhanced encryption key is sent through a separate quantum-protected tunnel and mesh network to multiple transmission points. This presents an attacker with the enormous challenge of having to defeat the combined security of Key Encrypting Key (KEK) – where a second key is in play and sent independent of the data path. Continuous key rotation takes place with every transfer, further enhancing the security of the system today and into the quantum future.

Phio TX embraces cryptographic agility, supporting quantum keys generated from any source, i.e. Quantum Key Distribution (QKD), Quantum Random Number Generator (QRNG) or a combination, and all post-quantum cryptographic (PQC) candidate algorithms evaluated by the National Institute of Standards and Technology (NIST) slated for standardization by 2022.

The FIPS validated network security appliance is also compliant with the European Telecommunications Standards Institute (ETSI) protocol for QKD. With Phio TX, users can start with PQC and then easily upgrade to QKD protection levels without disrupting their underlying infrastructure and without network downtime.

“Phio TX used in combination with Thales’s High Speed ​​Encryptors (HSE) provides customers with a powerful enterprise security solution capable of making native encryption keys immediately quantum-proof,” said Eddy Zervigon, CEO of Quantum Xchange. “The standards-based solution can easily meet a company’s risk mitigation needs at any time and provides an infinitely stronger cybersecurity posture to any network environment.”

“Quantum computing will be one of the greatest technological advancements in recent memory, but it comes with many security risks,” said Todd Moore, vice president of encryption products at Thales. “While there is no silver bullet in cybersecurity, deploying crypto-agile systems or systems that can quickly update cryptographic algorithms, keys, and certificates in response to advances in cyberattacks is the key. next frontier in protection against emerging threats.

“Today, Thales enables enterprises to flexibly deploy security algorithms, including quantum-resistant algorithms that provide techniques to mitigate current and future security risks presented by the evolution of quantum computing. . NIST is currently selecting finalists from quantum encryption algorithms under development. In anticipation of this, Thales is already supporting current finalists, including Thales’ Falcon Algorithm.
