Verified Correctness and Security of mbedTLS HMAC-DRBG
2017
Proceedings of the 2017 ACM SIGSAC Conference on Computer and Communications Security - CCS '17
Preserved Fulltext

We have formalized the functional specification of HMAC-DRBG (NIST 800-90A), and we have proved its cryptographic security--that its output is pseudorandom--using a hybrid game-based proof. ...
That proof composes with an existing C compiler correctness proof to guarantee, end-to-end, that the machine language program gives strong pseudorandomness. ...
