Unique SafeKey secure boot feature on SC14453S VOIP processor is based on Hardware Intrinsic Security technology
|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).
Security mechanisms using PUF technology aim at becoming an essential part of Hardware Intrinsic Security (HIS). HIS is based on the fact that secret keys are extracted like a silicon biometric or fingerprint from silicon hardware directly and only when required. Attackers have nothing to find because no key is stored nor present in the power down state.
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”.
“Dialog Semiconductor takes a lead position in providing the highest level of security in the VOIP processor market”, said Tony Picard, VP Business Development at Intrinsic-ID. “Our HIS-based security IP enables Dialog Semiconductor’s customers to ensure the integrity of their differentiating software with the highest level of anti-virus protection, through protecting their software with the electronic fingerprint that is unique for every device, making chips unclonable.”
