FIELD: device and method for data retranslation.
SUBSTANCE: data retranslation device for encoding input data and transferring encoded data to a predetermined device includes an input data processing block for receiving input data, encoding input data in a format fitting for predetermined device, and encoding input data with usage of common key, used in combination with predetermined device, and also data transfer protection block, which receives encoded data from input data processing block via a predetermined bus and retranslates received data to predetermined device. Also, a common key is generated in data transfer protection block and is transferred to input data processing block via a predetermined bus.
EFFECT: possible realization of simultaneous protection of data transfer line and internal protection without increase in complexity and costs of development.
