&quot;The cryptographic processing of the entropic data is implemented with a
well-known and well-studied deterministic random number generator: an SP800-90A DRBG as defined in [2] – naturally excluding the NSA-sponsored Dual-EC
DRBG.&quot;<p>&quot;The concept of the LRNG allows the selection of the used DRBG and
the backend cipher implementations at compile time.&quot;<p>Is SP800-90A DRBG  really state of the art?<p>According to Wikipedia &quot;the publication contains the specification for four cryptographically secure pseudorandom number generators for use in cryptography.&quot; Without Dual-EC it&#x27;s still three different DRBGs. How good are they? Is there anything better?
