Cryptanalysis of Stream Cipher DECIM
Stream cipher DECIM is a hardware oriented cipher with 80-bit key and 64-bit IV. In this paper, we point out two serious flaws in DECIM. One flaw is in the initialization of DECIM. It causes about half of the key bits being recovered bit-by-bit when one key is used with about 2 random IVs, and only the first two bytes of each keystream are needed in the attack. The amount of computations requir...
متن کاملCryptanalysis of RAKAPOSHI Stream Cipher
RAKAPOSHI is a hardware oriented stream cipher designed by Carlos Cid et al. in 2009. The stream cipher is based on Dynamic Linear Feedback Shift Registers, with a simple and potentially scalable design, and is particularly suitable for hardware applications with restricted resources. The RAKAPOSHI stream cipher offers 128-bit security. In this paper, we point out some weaknesses in the cipher....
متن کاملCryptanalysis of Stream Cipher Alpha1
Komninos, Honary and Darnell recently proposed stream cipher Alpha1. Alpha1 is based on A5/1 and is claimed to be much safer than A5/1. However Alpha1 is insecure: a 29-bit feedback shift register could be recovered with about 3000 known plaintext bits with O(2) operations. The rest of the message could be recovered in the broadcast application in which the same message is encrypted with differ...
متن کاملCryptanalysis of the Full Spritz Stream Cipher
Spritz is a stream cipher proposed by Rivest and Schuldt at the rump session of CRYPTO 2014. It is intended to be a replacement of the popular RC4 stream cipher. In this paper we propose distinguishing attacks on the full Spritz, based on a short-term bias in the first two bytes of a keystream and a long-term bias in the first two bytes of every cycle of N keystream bytes, where N is the size o...
متن کاملCryptanalysis of the Stream Cipher LEX
In [6], Biryukov presented a new methodology of stream cipher design called leak extraction. The stream cipher LEX, based on this methodology and on the AES block cipher, was selected to phase 3 of the eSTREAM competition. The suggested methodology seemed promising, and LEX, due to its elegance, simplicity, and performance, was expected to be selected to the eSTREAM portfolio. In this paper we ...
