In this paper, we examine effectiveness for clock control in stream ciphers with the aim of protecting against distinguishing attacks and guess-and-determine (GD) attacks. We model a typical clock-controlled stream cipher and analyze the increase of computational complexity of these attacks that results from using a clock control. We then examine parameters for a design of clock-controlled stream ciphers, such as the length of the LFSR used for the clock control. An optimal solution for designing clock control is to choose the clock pattern (the number of input bits) and the length of the LFSR for clock control carefully, adopting design criteria which we describe in this paper. |
