Random number generator software targets IoT devices

Intrinsic ID  announced Zign RNG, a new offering enabling IoT chip providers and device makers to establish a high-security random number generator in software enabling it to be deployed on devices even after silicon fabrication to ensure a true source of randomness for IoT devices.

Random number generators (RNGs) are essential for cryptographic applications and form the foundation of security systems. For IoT devices, an RNG is generally implemented by incorporating hardware peripheral controllers, which are proving to be imperfect as a source for real randomness because they start with a deterministic input. A report from Bishop Fox shows critical vulnerabilities have been disclosed in hardware random number generators used in billions of Internet of Things (IoT) devices whereby it fails to properly generate random numbers, thus undermining their security and putting them at risk of attacks.
