Abstract
In this paper we devise a generalization of the Geffe generator that combines more than three periodic inputs over GF(q). In particular, clock-controlled shift registers are suggested as inputs. The period and the linear complexity of the generated key-stream are estimated. We also prove some new results about the period of the sequence generated by a clock-controlled shift register.
