SSC2 is a stream cipher that operates by X ORing the output of two half-ciphers". The rst half-cipher is constructed from a linear feedback shift register LFSR with a non-linear lter. The second half-cipher is constructed from a lagged Fibonacci generator LFG and a m ultiplexor that chooses values from the Fibonacci register. The second half-cipher has a(More)
A rapid yet reliable procedure for the simultaneous extraction and assay of carbadox and pyrantel tartrate is described. The feed is extracted with water-acetonitrile-methanol and cleaned up on a short alumina column. The eluant is separated by high pressure liquid chromatography and the compounds are detected at different wavelengths. The drugs of interest(More)
