The future of cryptography is evolving rapidly, especially with the looming threat posed by quantum computers. Microsoft is at the forefront of preparing for this future through its Quantum Safe Program (QSP) and active participation in developing post-quantum cryptography (PQC) algorithms. Quantum computing, with its unique properties like superposition and entanglement, has the potential to disrupt current encryption methods based on public-key algorithms like RSA and ECC.
To address this challenge, researchers are developing PQC algorithms that are resistant to quantum attacks. Microsoft has integrated post-quantum algorithms like ML-KEM and XMSS into SymCrypt, its core cryptographic library used in various products and services. These algorithms offer high security and performance but may require larger key sizes and longer computation times.
Microsoft’s commitment to quantum readiness is evident through its involvement in NIST’s Post-Quantum Cryptography Standardization Process and collaborations with industry partners. The company aims to integrate PQC algorithms into its products and services to ensure quantum-safe transitions for its customers. Additionally, efforts are underway to standardize the use of PQC algorithms in communication protocols like TLS, SSH, and IPSec.
While PQC algorithms are relatively new, Microsoft emphasizes the importance of “Crypto Agility” to adapt to evolving standards. The transition to PQC is a complex process that requires careful planning and understanding of cryptographic assets. Microsoft offers assistance to organizations looking to navigate their transition to quantum safety.
By incorporating PQC algorithms into SymCrypt and advocating for crypto agility, Microsoft is paving the way for a quantum-safe world. Collaboration with the research community and standards bodies is crucial to advancing post-quantum cryptography and ensuring widespread adoption. Together, we can strengthen cryptography to safeguard information in the digital age.
