v2 ∗ DECIM
Decim is a hardware oriented stream cipher with 80-bit key and 64-bit IV which was submitted to the ECRYPT stream cipher project. The design of Decim is based on both a nonlinear filter LFSR and an irregular decimation mechanism called the ABSG. As a consequence, Decim is of low hardware complexity. Recently, Hongjun Wu and Bart Preneel pointed out two flaws in the stream cipher Decim. The firs...

متن کاملDecim − 128 ∗
Decim is a hardware oriented stream cipher submitted to the ECRYPT stream cipher project. The design of Decim is based on both a non linearly filtered LFSR and an irregular decimation mechanism called the ABSG. While the initial call for contributions required hardware-oriented stream ciphers to manage 80-bit secret keys and 64-bit public initialization, designers have been invited to demonstra...
متن کاملCryptanalysis 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 کاملA Method for Detecting and Blocking Instant Messaging Software
Instant messaging software, as a convenient network communication tool, is becoming more and more popular. At the same time, it also brings risks in security of local area network (LAN). Through studying in typical instant messaging software and detected by the combination of misuse detection and protocol analysis, an architecture of detecting and blocking mechanism of instant messaging softwar...
