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 and as such is able to offer an enhanced level of anti-tampering and anti-cloning characteristics.
This approach looks to 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”.
Commenting Tony Picard, VP Business Development at Intrinsic-ID said, “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.”
