In a significant advancement for online security, cryptographer Joppe Bos has co-authored a quantum-secure encryption algorithm, CRYSTALS-Kyber, which has been adopted as a standard by the U.S. National Institute of Standards and Technology (NIST). This new algorithm is already being integrated into various technology products, including Google’s Chrome browser, enhancing the security of users worldwide.
The rapid development of quantum computing has raised concerns that future devices could potentially break existing encryption methods, which rely on complex mathematical puzzles. Unlike classical computers, quantum computers can leverage quantum phenomena to solve these problems much faster, necessitating the development of new encryption methods.
NIST initiated a competition in 2016 to identify encryption solutions resilient to quantum attacks. The CRYSTALS-Kyber scheme emerged as a winner in 2022 and is now being implemented in embedded hardware products at NXP Semiconductors, where Bos leads the post-quantum cryptography team.
CRYSTALS-Kyber is notable for its lattice-based approach, which not only provides quantum security but also supports fully homomorphic encryption, allowing computations on encrypted data. This innovation is crucial as companies strive to meet government guidelines for transitioning to post-quantum encryption by the early 2030s.
As Bos integrates this algorithm into NXP’s products, he emphasizes the importance of collaboration across departments to ensure that these innovations translate into practical applications. His journey from academia to industry exemplifies the growing demand for cryptography experts, highlighting the field's welcoming nature and career prospects for those with a background in computer science or electrical engineering.
