Nestled in Leuven, Belgium, IMEC (Interuniversity Microelectronics Centre) stands as the world’s premier research hub for advanced semiconductor chip design. As AI models scale into trillions of parameters, cloud security has migrated down from software containers to hardware roots of trust and sub-2nm silicon enclaves.

Confidential Computing Era: Securing data at rest and in transit is no longer enough; hardware-enforced Confidential Computing encrypts data in use inside CPU and GPU memory enclaves.

        return True
    raise SecurityError("Attestation failed! Cloud host hypervisor may be compromised.")
