Microsoft is actively preparing for a future where quantum computers pose a significant threat to current encryption methods. The company is exploring Post-Quantum Cryptography (PQC) solutions, with a focus on algorithms like FrodoKEM, to bolster security on Windows and Linux platforms. This move is driven by the understanding that quantum computers, with their ability to solve complex problems exponentially faster than classical computers, could break the cryptographic backbone of today’s digital world, including systems like RSA, Diffie-Hellman, and elliptic curve cryptography. The urgency is underscored by recent advances like Microsoft’s Majorana 1, a quantum processor powered by topological qubits, which marks major steps toward practical quantum computing.

Microsoft's efforts to transition to quantum-resistant cryptographic systems include adding PQC algorithms to their core cryptography library, SymCrypt. Recently, Microsoft has taken the next step by adding PQC support to Windows Insiders (Canary Build 27852+) and to Linux through SymCrypt-OpenSSL v1.9.0. These additions allow companies and developers to start testing and preparing for a quantum-secure future, preventing a potential "harvest now, decrypt later" scenario where hackers collect encrypted data today to decrypt later using quantum computers using quantum computers. This proactive approach aims to safeguard digital lives against the looming quantum threat.

The new additions to Windows include ML-KEM (Module Lattice-Based Key Encapsulation Mechanism), also known as CRYSTALS-Kyber, designed for secure key exchange, and ML-DSA (Module Lattice-Based Digital Signature Algorithm), previously known as CRYSTALS-Dilithium, used for digital signatures to ensure data integrity and authenticity. NIST approved three PQC standards which are called FIPS 203, 204, and 205. FIPS 203 is a Module-Lattice-Based Key-Encapsulation Mechanism Standard that specifies a key encapsulation mechanism designed to protect information exchange over public networks, ensuring confidentiality even in the presence of quantum adversaries. FIPS 204 is a Module-Lattice-Based Digital Signature Standard that defines a digital signature scheme that provides authentication and integrity, crucial for verifying identities and securing communications. The FIPS 205:Stateless Hash-Based Digital Signature Standard outlines a stateless hash-based digital signature scheme, offering an alternative approach to digital signatures with strong security assurances. NIST encourages organizations to begin the transition to these new standards to ensure long-term data security.
