Towards a secure and low-power platform
An STRNG is a TRNG (True Random Number Generator) based on a Self-Timed Ring Oscillator.
The objective of an STRNG is to generate truly random numbers from electronic noise in a proven, secure and efficient way.
Don’t waste time and energy waiting for the noise to accumulate, but rather capture it as quickly as possible by sampling a very jittery signal.
RTL design
Down to 10 pJ/bits
Up to 400 Mbits/s
Configuration based on a stochastic model in line with AIS 31 (BSI standard)
An STRPUF is a PUF (Physically Unclonable Function) based on a Self-Timed Ring Oscillator.
The objective is to extract the process variation to build a secret ID unique to the circuit.
An STRPUF enables device identification and/or authentication, software to hardware binding, or secure storage of cryptographic secrets.
Instead of capturing the delay variations through frequency measurements, directly extract the actual delay.
