Compressed Sensing Encryption: Compressive Sensing Meets Detection Theory
Journal of Communications
Since compressive sensing utilizes a random matrix to map the sparse signal space to a lower dimensional transform domain, it may be possible to apply this matrix at the same time for encrypting the signal opportunistically. In this paper, a compressed sensing based encryption method is considered and the secrecy of the measurement matrix of compressive sensing analyzed from the detection theory perspective. Here the detection probabilities of the intended and unintended receivers are compareddoi:10.12720/jcm.13.2.82-87 fatcat:gss22rpu5fbqzosuqs6ixaqh5q
