In this paper a new state recovery attack with tabu search is introduced. Based on research and theoretical approximation it is shown that the internal state can be recovered after checking 252 internal states for RC4 and 2180 for VMPC.}, type={Artykuły / Articles}, title={Tabu Search Against Permutation Based Stream Ciphers}, URL={http://www.czasopisma.pan.pl/Content/103842/PDF/20_1157-4308-1-PB.pdf}, doi={10.24425/119361}, keywords={tabu search, TS, cryptanalysis, RC4, VMPC, stream cipher, state recovery attack}, }
