1 μrngd 2 ===== 3 4 μrngd is OpenWrt's micro non-physical true random number generator based on 5 timing jitter. 6 7 Using the Jitter RNG core, the rngd provides an entropy source that feeds into 8 the Linux /dev/random device if its entropy runs low. It updates the /dev/random 9 entropy estimator such that the newly provided entropy unblocks /dev/random. 10 11 The seeding of /dev/random also ensures that /dev/urandom benefits from entropy. 12 Especially during boot time, when the entropy of Linux is low, the Jitter RNGd 13 provides a source of sufficient entropy.
