eliavila10/project_biasВысокопроизводительный криптографический движок без смещений на Ada/SPARK, использующий собственные пулы энтропии ОС.
Высокопроизводительный криптографический потоковый движок без смещения, написанный на Ada и формально верифицированный с помощью SPARK. Движок гарантирует нулевое статистическое смещение при отображении сырой энтропии в пользовательские алфавиты, отбрасывая значения со смещением от операции modulo, и получая криптографические байты напрямую из собственных пулов ядра ОС.
Движок взаимодействует напрямую с низкоуровневыми API ОС через Interfaces.C, чтобы устранить уровни абстракции и задержки:
ProcessPrng) в качестве основного источника сырых криптографических байтов.bcrypt.dll).-- Formula applied to enforce uniform distribution without modulo bias:
-- Formul = Charset'Length * (256 / Charset'Length) - 1
-- Any extracted byte > Formula'result = it is ruled out
Чтобы проверить математическую равномерность алгоритма отображения без смещения, движок был подвергнут стресс-тесту, сгенерировавшему 1,010,762,506,054 символов (более 1 терабайта) из алфавита из 69 символов.
