April 25, 2012 -- The Dialog Semiconductor GmbH SC14453S is the 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.

"We selected Intrinsic-ID's HIS technology because of its proven reliability, ease of integration and cost-effective silicon area footprint," said René Kohlmann, Senior Director at Dialog Semiconductor. "The resulting SafeKey solution for secure boot is programmable while at the same time providing authentication and top-level security."
