On the security of compressed encryption with partial unitary sensing matrices embedding a secret keystream

Abstract The principle of compressed sensing (CS) can be applied in a cryptosystem by providing the notion of security. In this paper, we study the computational security of a CS-based cryptosystem that encrypts a plaintext with a partial unitary sensing matrix embedding a secret keystream. The keys...
