 Кто это? - спросил. - Сьюзан Флетчер, - ответил Бринкерхофф. Человек-гигант удивленно поднял брови. Даже перепачканная сажей и промокшая, Сьюзан Флетчер производила более сильное впечатление, чем он мог предположить. - А коммандер? - спросил .

Он достаточно долго проработал бок о бок с директором и знал, что перерыв не относился к числу поощряемых им действий - особенно когда дело касалось ТРАНСТЕКСТА. Фонтейн заплатил за этого бегемота дешифровки два миллиарда и хотел, чтобы эти деньги окупились сполна. Каждая минута простоя ТРАНСТЕКСТА означала доллары, спущенные в канализацию. - Но, Мидж… - сказал Бринкерхофф.  - ТРАНСТЕКСТ не устраивает перерывов. Он трудится день и ночь.

Первое упоминание о меняющемся открытом тексте впервые появилось в забытом докладе венгерского математика Джозефа Харне, сделанном в 1987 году. Ввиду того что компьютеры, действующие по принципу грубой силы, отыскивают шифр путем изучения открытого текста на предмет наличия в нем узнаваемых словосочетаний, Харне предложил шифровальный алгоритм, который, помимо шифрования, постоянно видоизменял открытый текст. Теоретически постоянная мутация такого рода должна привести к тому, что компьютер, атакующий шифр, никогда не найдет узнаваемое словосочетание и не поймет, нашел ли он искомый ключ. Вся эта концепция чем-то напоминала идею колонизации Марса - на интеллектуальном уровне вполне осуществимую, но в настоящее время выходящую за границы человеческих возможностей. - Откуда вы взяли этот файл? - спросила .
