CRYPTOSYSTEM USING COMPRESSIVE SENSING AND OPERATING METHOD THEREOF

摘要

According to the present invention, an operation method of a compressive sensing encryption system comprises the steps of: performing compressive sensing for an information signal using a sensing matrix; 1-bit-quantizing the compressive sensed signal; and adding artificial noise to the quantized signal. According to an embodiment of the present invention, a compressive sensing encryption system and an operation method thereof may reduce hardware complexity and improve security through quantization error by using a 1-bit compressive sensing encryption scheme and a retransmission strategy having interleaving for a multi-carrier system.
