New Weaknesses in the Keystream Generation Algorithms of the Stream Ciphers TPy and Py
The stream ciphers Py, Py6 designed by Biham and Seberry were promising candidates in the ECRYPT-eSTREAM project because of their impressive speed. Since their publication in Apri...

New Attacks on the Stream Cipher TPy6 and Design of New Ciphers the TPy6-A and the TPy6-B
The stream ciphers Py, Pypy and Py6 were designed by Biham and Seberry for the ECRYPT-eSTREAM project in 2005. The ciphers were promoted to the ‘Focus’ ciphers of the Phase II ...

On the (In)security of Stream Ciphers Based on Arrays and Modular Addition
Abstract. Stream ciphers play an important role in symmetric cryptology because of their suitability in high speed applications where block ciphers fall short. A large number of fa...

Analysis of Non-fortuitous Predictive States of the RC4 Keystream Generator
The RC4 stream cipher is the most widely used software based stream cipher. It is based on a secret internal state of N = 256 bytes and two pointers. This paper proposes an efficie...

Attack the Dragon
1 Dragon is a word oriented stream cipher submitted to the ECRYPT project, it operates on key sizes of 128 and 256 bits. The original idea of the design is to use a nonlinear feedb...
