Leveraging an initial partnership with the TIMA Laboratory, we have the expertise to uniquely combine hardware security features and low-power in a custom ASIC solution for the needs of IoT and medical applications.


STRNG principles
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.
STRNG benefits
Configurability
RTL design
High power efficiency
Down to 10 pJ/bits
High bit rate
Up to 400 Mbits/s
Reliable solution
Configuration based on a stochastic model in line with AIS 31 (BSI standard)
STRPUF principles
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.

STRPUF benefits
x1000 response latency improvement versus traditional ROPUF (ring oscillator PUF)
