Abstract

Изобретение относится к вычислительной технике, и в частности к устройствам защиты информации от несанкционированного доступа к ЭВМ. Устройство содержит по крайней мере один электронный ключ, предназначенный для соединения с соответствующими контактами входного и выходного соединителя и управляемый от дешифратора, входы которого служат для соединения с соответствующими контактами входного и/или выходного соединителя, предназначенными для передачи данных. Кроме того, устройство может быть снабжено блоком памяти, например энергонезависимым блоком памяти типа электрически стираемой перепрограммируемой постоянной памяти, который управляется от другого дешифратора. Дешифраторы и электронный ключ могут быть выполнены в виде сдвоенного селектора-мультиплексора, типа единого узла-чипа. Все устройство может быть выполнено в виде единого чипа. Такое выполнение устройства позволяет значительно повысить защищенность от несанкционированного доступа к ЭВМ и программным продуктам.The invention relates to computing, and in particular to devices for protecting information from unauthorized access to a computer. The device contains at least one electronic key intended for connection with the corresponding contacts of the input and output connector and controlled from a decoder, the inputs of which are used for connection with the corresponding contacts of the input and / or output connector for data transmission. In addition, the device can be equipped with a memory unit, such as a non-volatile memory unit of the type of electrically erasable reprogrammable permanent memory, which is controlled from another decoder. Decoders and electronic key can be made in the form of a dual selector-multiplexer, such as a single node-chip. The entire device can be made as a single chip. This embodiment of the device can significantly increase the security from unauthorized access to computers and software products.
