Crypta Labs guides OEMs on building quantum-safe random number systems

Quantum ZeitgeistSeptember 28, 20265 min read

Poor entropy quality can cripple security, even with robust crypto—this guide helps OEMs build FPGA & MCU systems with truly unpredictable values for key generation and beyond, preparing for post-quantum threats.

Crypta Labs is guiding manufacturers to scrutinize a surprisingly fragile point in system security: the source of randomness. A security appliance with an approved cryptographic library, a secure element, and a well-protected key store can still fail due to insufficient entropy quality and availability, the company warns. OEMs designing FPGA- and MCU-based products must consider the “full path from physical entropy source to consuming cryptographic function” for unpredictability, health, fault containment and repeatability, especially for products operating unattended for years. This focus on long-term, sustained security is critical as entropy architecture begins with identifying every function…
