Scan-based Attacks on Linear Feedback Shift Register Based Stream Ciphers
Stream Ciphers LFSRs Scan DFT
2009/12/29
In this paper, we present an attack on stream cipher implementations by determining the scan chain structure of the linear feedback shift registers in their implementations. Although scan Design-for-T...
High Efficiency Feedback Shift Register: $\sigma-$LFSR
Linear Feedback Shift Register Finite Field Stream Cipher
2008/9/5
We introduce a new kind of word-oriented linear feedback
shift register called LFSR which is constructed with the instructions
of the modern processor and have fast software implementation. We of-
