PUFhsm is an advanced Hardware Security Module (HSM) developed specifically for automotive and other high-security applications. It serves as an 'Embedded Security Enclave', freeing the main CPU from handling secure tasks while ensuring comprehensive protection through EVITA-Full compliance. With capabilities such as secure boot, updates, provisioning, and lifecycle management, PUFhsm stands as a robust solution for fulfilling stringent security requirements. The module integrates cryptographic engines and a dedicated CPU, and offers extensive features for managing cryptographic keys and securing communications. By adopting PUFhsm, designers can enhance security architectures, minimizing tampering risks and improving the overall reliability of systems in mission-critical environments.
