New Hybrid Efficient Stream Cipher KeyGenerator Based on LFSR's and Chaotic Map
Ibn Al-Haitham Journal for Pure and Applied SciencesCommunication security that depends on chaos can be considered as a new approach which provides protection and security of communications and maintains confidentiality because Chaos theory can be implemented in cryptosystem successfully.

Multilevel Permutation with Different Block Size/ Stream Cipher Image Encryption [PDF]
Iraqi Journal for Electrical and Electronic Engineering, 2015 In this work, a new image encryption method using a combined multilevel permutation with stream cipher is proposed. In the permutation algorithm, image is divided into blocks in each level and its blocks are rearranged by using pseudorandom permutation

Modes of Operation of Stream Ciphers [PDF]
, 2001 A general stream cipher with memory in which each cipher-text symbol depends on both the current and previous plaintext symbols, as well as each plaintext symbol depends on both the current and previous ciphertext symbols, is pointed out. It is shown how to convert any keystream generator into a stream cipher with memory and their security is discussed.

State convergence in the initialisation of the Sfinks stream cipher
, 2012 Sfinks is a shift register based stream cipher designed for hardware implementation. The initialisation state update function is different from the state update function used for keystream generation.

A new fast stream cipher: MAJE4
, 2005 A new fast stream cipher, MAJE4 is designed and developed with a variable key size of 128-bit or 256-bit. The randomness property of the stream cipher is analysed by using the statistical tests.

Weaknesses in HENKOS Stream Cipher [PDF]
, 2008 HENKOS is a synchronous stream cipher posted by Marius Oliver Gheorghita to eprint. In this paper we are going to present some weaknesses in the cipher. We first present a chosen IV attack which is very straight forward attack on the cipher.
