Decim v2

Abstract : In this paper, we present Decimv2, a stream cipher hardware- oriented selected for the phase 3 of the ECRYPT stream cipher project eSTREAM. As required by the initial call for hardware-oriented stream cipher contribution, Decimv2 manages 80-bit secret keys and 64-bit public initialization vectors. The design of Decimv2 combines two filtering mechanisms: a nonlinear Boolean filter over a LFSR, followed by an irregular decimation mechanism called the ABSG. Since designers have been invited to demonstrate flexibility of their design by proposing vari-ants that take 128-bit keys, we also present a 128-bit security version of Decim called Decim-128.
