Abstract
A new family of stream ciphers, Grain, is proposed. Two variants, a 80-bit and a 128-bit variant are specified, denoted Grain and Grain-128 respectively. The designs target hardware environments where gate count, power consumption and memory are very limited. Both variants are based on two shift registers and a nonlinear output function. The ciphers also have the additional feature that the speed can be easily increased at the expense of extra hardware.
