The Subterranean 2.0 Cipher Suite

open access: yesIACR Transactions on Symmetric Cryptology, 2020
This paper presents the Subterranean 2.0 cipher suite that can be used for hashing, MAC computation, stream encryption and several types of authenticated encryption schemes. At its core it has a duplex object with a 257-bit state and a lightweight single-

Chosen-Plaintext Cryptanalysis of a Clipped-Neural-Network-Based Chaotic Cipher [PDF]

open access: yes, 2005
In ISNN'04, a novel symmetric cipher was proposed, by combining a chaotic signal and a clipped neural network (CNN) for encryption. The present paper analyzes the security of this chaotic cipher against chosen-plaintext attacks, and points out that this ...

Two-Layer Security Algorithms to Prevent Attacks on Data in Cyberspace

open access: yesApplied Sciences, 2022
The ratio at which the number of users is increasing in cloud computing, the same as the number of data destruction, has doubled. Various algorithms have been designed to secure cloud servers to prevent an attacker from attacking, but they cannot protect

Deciphering a novel image cipher based on mixed transformed Logistic maps [PDF]

open access: yes, 2015
Since John von Neumann suggested utilizing Logistic map as a random number generator in 1947, a great number of encryption schemes based on Logistic map and/or its variants have been proposed. This paper re-evaluates the security of an image cipher based

WATERMARKING CIPHERS [PDF]

open access: yesPrikladnaya diskretnaya matematika, 2015
Summary: In order to protect both data confidentiality and legality, a concept of a watermarking cipher (also called a w-cipher) is defined. The main idea of this cjncept is as follows: the transformation of a plaintext \(x\) by the composition of encryption and decryption operations using some encryption and decryption keys yields a proper text \(x ...
