COUNTER MODE DEVELOPMENT FOR BLOCK CIPHER OPERATIONS [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 There are two basic types of symmetric cipher: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer. Stream ciphers operate on streams of plaintext and ciphertext one bit or

Atom: A Stream Cipher with Double Key Filter
IACR Transactions on Symmetric Cryptology, 2021 It has been common knowledge that for a stream cipher to be secure against generic TMD tradeoff attacks, the size of its internal state in bits needs to be at least twice the size of the length of its secret key.

Using Evolving Algorithms to Cryptanalysis Nonlinear Cryptosystems
مجلة بغداد للعلوم, 2020 In this paper, new method have been investigated using evolving algorithms (EA's) to cryptanalysis one of the nonlinear stream cipher cryptosystems which depends on the Linear Feedback Shift Register (LFSR) unit by using cipher text-only attack.

Vectorization on ChaCha Stream Cipher [PDF]
2014 11th International Conference on Information Technology: New Generations, 2014 This paper describes software optimization for the stream Cipher ChaCha. We leverage the wide vectorization capabilities of the new AVX2 architecture, to speed up ChaCha encryption (and decryption) on the latest x86_64 processors. In addition, we show how to apply vectorization for the future AVX512 architecture, and get further speedup.

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
