LILI Keystream Generator
The LILI-128 keystream generator is a LFSR based synchronous stream cipher with a 128 bit key. The design offers large period and linear complexity, and is resistant to currently ...

Cryptanalysis of the Stream Cipher DECIM
DECIM is a hardware oriented stream cipher with an 80-bit key and a 64-bit IV. In this paper, we point out two serious flaws in DECIM. One flaw is in the initialization of DECIM. I...

Differential Cryptanalysis of the Stream Ciphers Py, Py6 and Pypy
This paper shows that Py and Pypy are practically insecure. If one key is used with about 216 IVs with special differences, with high probability two identical keystreams will appe...

Cryptanalysis of Achterbahn
We present several attacks against Achterbahn, one of the new stream ciphers proposed to the eSTREAM competition. Our best attack breaks the reduced version of the cipher with comp...

A New Approach for FCSRs
The Feedback with Carry Shift Registers (FCSRs) have been proposed as an alternative to Linear Feedback Shift Registers (LFSRs) for the design of stream ciphers. FCSRs have good st...
