Dialog Semiconductor to license the safe boot and unclonability features of Intrincis-ID. R. Colin Johnson
Here is what Intrisic-ID says about the new VoIP chip: The Dialog Semiconductor SC14453S is the world’s first commercially available Voice over IP (VoIP) processor circuit that integrates 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.
