Analysis of the RSA-cryptosystem in abstract number rings

Журнал Белорусского государственного университета: Математика, информатика, 2020
Quantum computers can be a real threat to some modern cryptosystems (such as the RSA-cryptosystem). The analogue of the RSA-cryptosystem in abstract number rings is not affected by this threat, as there are currently no factorization algorithms using ...

Compression Cryptosystem

The Computer Journal
Abstract A compression cryptosystem is a single coding process, the output of which is both reduced in space and secure against unauthorized decoding. Considering both Huffman and arithmetic coding, this paper proposes to apply repeatedly minor changes to the compression model, with negligible deterioration of its optimality.

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 ...
