Abstract
Настоящее изобретение относится к способу формирования шифровального/дешифровального ключа и, в частности, формирования одноразового шифровального/дешифровального ключа, используемого для симметричного шифрования, т.е. где один и тот же ключ используется как для шифрования, так и для дешифрования. Для того чтобы начать формирование ключа, первый узел (А) посылает запрос центральному серверу (2) для установления связи со вторым узлом (В). Центральный сервер (2) посылает файл генерации ключа, обоим узлам (А и В). Каждый узел формирует особый промежуточный набор данных, т.е. первый и второй наборы данных. Первый набор данных, сформированный первым узлом (А), посылается второму узлу (В), который на основе этого набора данных формирует третий набор данных, который посылается обратно первому узлу. Формирование первого криптографического ключа в узле (А) основано на побитовом сравнении между третьим и первым промежуточными наборами данных, а формирование второго криптографического ключа основано на побитовом сравнении между первым и вторым промежуточными наборами данных. Первый и второй криптографические ключи идентичны.
