It explains Lai's idea of mixing incompatible algebraic operations together and gives the theoretical basis for such constructions. Further, the book contains material about the differential cryptanalysis of IDEA and why IDEA should be resistant to it. Contains also an implementation of IDEA in C language. This is a very large collection of survey articles. There is an article by Ron Rivest on cryptography, also an article by Arjen Lenstra and Hendrik Lenstra on algorithms in number theory.
All articles have extensive references.
