Retiming is a transformation that optimizes a sequential circuit by relocating the registers. When the circuit has an initial state, one must compute an equivalent initial state f...
Geometrical symmetries are commonly exploited to improve the efficiency of search algorithms. We introduce a new logical symmetry in permutation state spaces which we call duality...

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...
1 We present a new type of Linear Feedback Shift Registers, State Skip LFSRs. State Skip LFSRs are normal LFSRs with the addition of a small linear circuit, the State Skip circuit,...
