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

EURASIP Journal on Advances in Signal Processing, 2017
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 ...

Understanding the NTRU Cryptosystem [PDF]

, 2019
In this paper, we will examine the NTRU Public Key Cryptosystem. The NTRU cryptosystem was created by Joseph Silverman, Jeffery Hoffstein, and Jill Pipher in 1996. This system uses truncated polynomial rings to encrypt and decrypt data.
