Abstract :
We consider the pk -ary frequency/time hopping (FH/TH) sequence generator composed of a combinatorial function generator and k registers. We consider possible attacks on the FH/TH sequence generator and characterize the generator with desired cryptographic properties to resist these possible attacks on a case by case basis.
