WebSep 21, 2013 · Backtracking resistance is provided by ensuring that the DRBG generator algorithm is a one-way function. This is easy: all the DRBG mechanisms in NIST SP800-90 provide backtracking resistance. Prediction resistance depends on the Reseed process; that is, the ability to effectively reseed after a compromise but before the next request. WebThe DRBG produces a sequence of bits from a secret initial value called a seed, along with other possible inputs. A DRBG is often called a Pseudorandom Number (or Bit) Generator.
