%X A new clock-controlled key-stream generator is proposed in this paper. The generator is composed of three shift registers: two clock-controlled linear feedback shift registers, A and B, and one clock-controlled nonlinear feedback shift register C. The clock-controlled information is from two bit strings of feedback shift register C. The times A and B shift are according to the Hamming weights of the two strings, respectively. The period, the linear complexity and the k error linear complexity of the key-stream generator are studied, and the security of it is analyzed.
