# Entropy theatre presented as a security control

An unusual randomness source is used and publicised in place of a vetted CSPRNG, sometimes with no independent check that it produced high-quality, unpredictable, unrecoverable bits.

**Mitigation:** Use the platform CSPRNG as the primary source. Additional entropy may be mixed in, and may be filmed for communication purposes, but the security argument must not depend on it.
