Description

The number of hardware applications requiring a hardware Random Number Generator (RNG) is continuously increasing, specially in embedded circuits (e.g. Field Programmable Gate Array (FPGA) or System-on-Chip). As a consequence, many applications need an embedded RNG with the highest quality and security level. The OCHRE V1 chip implements a hybrid RNG composed of a True Random Number Generator (TRNG) and a Pseudo Random Number Generator (PRNG). The TRNG randomness quality is monitored on real-time by hardware statistical tests. As a result, the design is able to detect TRNG weaknesses due to defects or to non-invasive attacks.
