SEALSQ emphasizes the importance of crypto-agility in hardware architectures to counter emerging cryptographic threats, particularly as AI accelerates cryptanalysis and vulnerability research. Although current AI-assisted cryptanalysis does not compromise NIST-standardized post-quantum algorithms, it underscores the need for adaptable security systems1. SEALSQ is developing hardware platforms that integrate post-quantum cryptography, secure key storage, and update capabilities, which is crucial for long-lived connected devices. The company's efforts are driven by the shifting threat model from criminal to geopolitical, given state-aligned activity involving post-quantum cryptography. This shift necessitates a different approach to security, one that prioritizes flexibility and adaptability. As a result, practitioners must reevaluate their security strategies to stay ahead of potential threats, making crypto-agility a critical component of their defense mechanisms.
