Summary[edit]

Description
Русский: Простая атака с перехватом посылки. Ева перехватывает каждый фотон, предназначенный для Боба, случайным образом выбирает базис для измерения, получает результат и отправляет идентичный фотон Бобу. Измерение Евы разрушает суперпозицию состояние и разрушает квантовую когерентность, ответственную за идеальные антикорреляции в любом базисе. Конечным результатом является повышенная частота ошибок, которую Алиса и Боб могут обнаружить и тем самым определить, что их ключ небезопасен.
