Sigstore cosign-verify checks signed AI models on-device with 150-line C verifier

Developers can verify signed AI models on edge devices using a small, freestanding C verifier requiring no memory allocation or dependencies. The tool uses Sigstore cosign signatures and Android's libmincrypt P-256 and SHA-256 code to check model authenticity before loading. It is designed to run inside kernel modules to secure model deployment against tampering. Open article →
