-LFSR is a word-oriented feedback shift register with a good tradeoff between security and efficiency. As an example, using -LFSR in ABC increases its period from 232(2127-1) to 232(2128-1) and, more important, its Hamming weight with the feedback polynomial of equivalent LFSR over binary field from 3 to 65, which is just half of the degree 128. Consequently, its resistance to fast correlation attack is consolidated while the guaranteed efficiency in software is almost the same.
