Abstract: Cryptography to me is "black magic," enabling tasks that often seem paradoxical or simply just impossible. Like the space explorers, we cryptographers often wonder, "What are the boundaries of this world of 'black magic'?" This book lays one of the founding stones in furthering our understanding of these edges.

Cryptography to me is "black magic," enabling tasks that often seem paradoxical or simply just impossible. Like the space explorers, we cryptographers often wonder, "What are the boundaries of this world of 'black magic'?" This book lays one of the founding stones in furthering our understanding of these edges.
