Security Analysis for Randomness Improvements for Security Protocols

Liliya Akhmetzyanova and Cas Cremers and Luke Garratt and Stanislav V. Smyshlyaev

Abstract: Many cryptographic mechanisms depend on the availability of secure random numbers. In practice, the sources of random numbers can be unreliable for many reasons. There exist ways to improve the reliability of randomness, but these often do not work well with practical constraints. One proposal to reduce the impact of untrusted randomness is the proposal by Cremers et al. [draft-irtf-cfrg-randomness-improvements-03.txt], which aims to be effective in existing deployments.
