Cryptanalysis of the stream cipher BEAN [PDF]
Proceedings of the 4th international conference on Security of information and networks, 2011 BEAN is a recent stream cipher proposal that uses Feedback with Carry Shift Registers (FCSRs) and an output function. There is a sound motivation behind the use of FCSRs in BEAN as they provide several cryptographically interesting properties. In this paper, we show that the output function is not optimal.

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.
