Abstract:
   Randomness is a crucial ingredient for Transport Layer Security (TLS)
   and related security protocols.  Weak or predictable
   "cryptographically-strong" pseudorandom number generators (CSPRNGs)
   can be abused or exploited for malicious purposes.  The Dual_EC_DRBG
   random number backdoor and Debian bugs are relevant examples of this
   problem.  An initial entropy source that seeds a CSPRNG might be weak
   or broken as well, which can also lead to critical and systemic
   security problems.  This document describes a way for security
   protocol participants to augment their CSPRNGs using long-term
   private keys.  This improves randomness from broken or otherwise
   subverted CSPRNGs.

   This document is a product of the Crypto Forum Research Group (CFRG)
   in the IRTF.
