Enhancing Embedded Data Security By Turns Cipher Block Chaining Mode Into Stream Cipher [PDF]
Engineering and Technology Journal, 2009 In this paper, a secure data hiding method is introduced. It increases the security of embedded data through combining between the steganography and cryptography. First, the secrete message is divided into blocks with same size according to length of key

Counter Mode Development for Block Cipher Operations [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 There are two basic types of symmetric algorithms: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer.

An algebraic attack on stream ciphers with application to nonlinear filter generators and WG-PRNG [PDF]
, 2021 In this paper, we propose a new algebraic attack on stream ciphers. Starting from the well-known attack due to Courtois and Meier, we design an attack especially effective against nonlinear filter generators. We test it on two toy stream ciphers and we show that the level of security of one of stream ciphers submitted to the NIST competition on ...

Provable security against generic attacks on stream ciphers
Journal of Mathematical Cryptology, 2023 Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

BLOSTREAM: A HIGH SPEED STREAM CIPHER [PDF]
Journal of Engineering Science and Technology, 2017 Although stream ciphers are widely utilized to encrypt sensitive data at fast speeds, security concerns have led to a shift from stream to block ciphers, judging that the current technology in stream cipher is inferior to the technology of block ciphers.

Strike: Stream Cipher Based on Stochastic Lightning Strike Behaviour
Applied Sciences, 2023 There is an increasing need for secure and fast encryption algorithms to support applications and communication protocols, and business models. In this paper, we present an alternative stream cipher (Strike) inspired by the stochastic behaviour of ...

Side Channel Attack On Stream Ciphers: A Three-Step Approach To State/Key Recovery
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Side Channel Attack (SCA) exploits the physical information leakage (such as electromagnetic emanation) from a device that performs some cryptographic operation and poses a serious threat in the present IoT era. In the last couple of decades, there have
