In this paper, we present the rainbow attack on stream ciphers filtered by Maiorana-McFarland functions. This can be considered as a generalization of the time-memory-data trade-off attack of Mihalje-vic and Imai on Toyocrypt. First, we substitute the filter function in Toy-ocrypt (which has the same size as the LFSR) with a general Maiorana-McFarland(More)
In this paper the impact of the more recent stream cipher attacks like time-memory-data trade-off attacks and algebraic attacks on filter function keystream generators are studied. The attacks succeed when the filter function is based on concatenation of linear functions. As an alternative, some known constructions based on finite fields which are not(More)
In this paper, we present the time-memory-data (TMD) trade-off attack on stream ciphers filter function generators and filter cominers based on Maiorana-McFarland functions. This can be considered as a generalization of the time-memory-data trade-off attack of Mihaljevic and Imai on Toyocrypt. First, we substitute the filter function in Toyocrypt (which has(More)
