Modern cryptology more and more employs mathematically rigorous concepts and methods from complexity theory. Conversely, current research topics in complexity theory often are motivated by questions and problems from cryptology. This book takes account of this situation and therefore its subject is what may be dubbed "cryptocomplexity,'' some sort of symbiosis of these two areas. Starting from scratch, it works its way to the frontiers of current research in these fields and provides a detailed overview of their history and their current research topics and challenges.

First book focusing on the interrelation of Cryptology and Complexity Theory Includes supplementary material: sn.pub/extras
