Preface to the Revised Edition
Preface to the Revised Edition
Since the publication of this monograph in 1998, a considerable amount of advances on interactions between stream ciphers and number theory has been made. The objective of this revised edition is to report the recent advances and correct typos and errors in the original version. Most chapters are revised. In particular, Chapter 6 is completely rewritten. We thank Y.-H. Park, D. Hong and E. Chun for pointing out an error in computing the linear complexity of the prime-square generator in Chapter 8 of the original edition. We are grateful to S.S. Bedi and R. Pillai for pointing an error in Section 14.6, and for providing us with the source code of their C-implementation of the 2-RA algorithm.
