MIT researchers designed a CMOS manufacturing process wherein a chip is split during fabrication, yielding two halves that share an identical, device-unique fingerprint. This approach eliminates the need to store secret fingerprint information on third-party servers, mitigating associated security vulnerabilities.
The method is low-cost, compatible with standard CMOS foundry processes, and requires no special materials. It's targeted at power-sensitive paired devices like ingestible sensors and wearables, allowing direct mutual authentication. While claims include enhanced security by keeping secrets within silicon, broader independent validation would clarify robustness and scalability.
