‘Unclonable’ security ICs with ChipDNA technology launched to protect IoT customers

#News(Security) [ via IoTForIndiaGroup ]

Designers can now proactively and inexpensively protect their intellectual property (IP) and products with a solution that is claimed to be immune to invasive physical attacks.

So says US-based Maxim Integrated Products, Inc which has launched the DS28E38 DeepCover® secure authenticator.
The DS28E38 features Maxim’s ChipDNA physical unclonable function (PUF) technology, which the company claims makes it “immune to invasive attacks” because the ChipDNA-based root cryptographic key does not exist in memory or any other static state. Instead, Maxim’s PUF circuit relies on the naturally occurring random analogue characteristics of fundamental MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor) semiconductor devices to produce cryptographic keys.
