WebJun 1, 2024 · No, assuming you mean the CSPRNG is just AES in CTR, the state is simply the key and the IV, therefore compromise will allow trivial generation of both past and future outputs. Exposure of just the key is also as bad, as you can decrypt the output using the key (in ECB mode) to recover the IV. Which is why in NIST.SP.800-90A, The counter mode ... WebFeb 24, 2024 · You can also get a CSPRNG from any good stream cipher (e.g. the ones from the eSTREAM portfolio) or by running a block cipher (with large blocks, 128 bits or more) in CTR mode.
