Microsoft Brings Post-Quantum Security To Windows 11 And Linux

Microsoft is incorporating post-quantum cryptography (PQC) into Windows 11 and Linux platforms to enhance its security framework against potential threats from quantum computing. PQC functionalities are now available to Windows Insiders via the Canary Channel Build 27852 and on Linux through SymCrypt-OpenSSL version 1.9.0, allowing customers to test quantum-resistant encryption. Microsoft is enhancing its core cryptographic library, SymCrypt, with new PQC algorithms designed to withstand future quantum decryption capabilities. The company emphasizes the importance of "crypto agility," enabling systems to adapt to new algorithms as they develop. This initiative is part of Microsoft's ongoing commitment to global quantum-safe initiatives and aims to foster innovation and preparedness within the cybersecurity community.

Windows 11 is getting top-level protection against the next generation of quantum cyberattacks

Microsoft has announced new protective measures against potential quantum-powered cyber threats by rolling out post-quantum cryptography (PQC) capabilities for Windows Insiders using Canary Channel Build 27852 and higher, and for Linux users through SymCrypt-OpenSSL version 1.9.0. The newly introduced PQC algorithms, standardized by NIST, will evolve in response to emerging threats, emphasizing the need for "Crypto Agility." The updates enhance OpenSSL’s API surface for Linux developers, allowing experimentation with TLS hybrid key exchange. Experts warn that quantum computing could breach even the most robust encryption systems, highlighting the urgency for software companies to adapt their security measures.

Windows 11 gets quantum-hardened cryptography technology

Microsoft has integrated post-quantum cryptography (PQC) into Windows 11, starting with the Canary build 27852, to protect against quantum computer threats. The upgrade to SymCrypt, Microsoft's cryptographic library, now supports two PQC algorithms: ML-KEM and ML-DSA. This enhancement aims to improve security, performance, and compatibility across platforms. PQC is also being adopted in industry standards such as TLS, SSH, and IPSec. SymCrypt underpins various Microsoft services and operating systems, including Microsoft 365, Azure, and Windows 11. Microsoft is preparing its ecosystem for future quantum attacks, with PQC currently trialed in Windows 11 and expected to reach Linux soon. There are no specific timelines for updates to BitLocker. Recent research demonstrated a D-Wave quantum computer's ability to crack military-grade encryption, highlighting the increasing threat of quantum computing to classical cryptography.
