In March 2014, it was reported by Reuters that RSA had also adapted the extended random standard championed by NSA. Later cryptanalysis showed that extended random did not add any security, and was rejected by the prominent standards group Internet Engineering Task Force. Extended random did however make NSA's backdoor for Dual_EC_DRBG tens of thousands of times faster to use for attackers with the key to the Dual_EC_DRBG backdoor (presumably only NSA), because the extended nonces in extended random made part of the internal state of Dual_EC_DRBG easier to guess. Only RSA Security's Java version was hard to crack without extended random, since the caching of Dual_EC_DRBG output in e.g. RSA Security's C programming language version already made the internal state fast enough to determine. And indeed, RSA Security only implemented extended random in its Java implementation of Dual_EC_DRBG.
