The SC14453S from Dialog Semiconductor is claimed to be the world's first commercially available Voice over IP processor circuit to integrate Intrinsic-ID's patented Hardware Intrinsic Security IP, also referred to as Physical Unclonable Function (PUF).
In Hardware Intrinsic Security (HIS) technology a secret key is extracted like a silicon biometric or fingerprint from silicon hardware directly and only when required. By using this HIS-based fingerprint a firm binding of software and hardware is possible, offering superior levels of anti-tampering and anti-cloning characteristics.
This approach can ensure that only authenticated software can run on the SC14453S platform. A message authentication tag for a bootloader or software image of a particular customer is securely stored with the HIS IP of Intrinsic-ID, without the need for embedded non-volatile memory.
Attackers have nothing to find because no key is stored nor present in the power down state. Intrinsic-ID's security IP is said to excel by its ease-of-integration in a standard manufacturing flow, its availability in all modern technology nodes, its scalability and small area and/or SW footprint enables mass-scale deployment in cost-sensitive consumer applications.
