On a clock-controlled keystream generator and its cryptographic properties
A new clock-controlled keystream generator was proposed,which was composed of three shift registers: two clock-controlled linear feedback shift registers A,B,and one clock-controlling nonlinear feedback shift register C.Let l1,l2 and l3 denote the length of A,B and C,respectively.The clock-control i...

| description | A new clock-controlled keystream generator was proposed,which was composed of three shift registers: two clock-controlled linear feedback shift registers A,B,and one clock-controlling nonlinear feedback shift register C.Let l1,l2 and l3 denote the length of A,B and C,respectively.The clock-control information is from two bit strings of feedback shift register C,and 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 keystream generator are studied,and its security was analyzed. |
