Probabilistic and Statistical Methods in Cryptology : An Introduction by Selected Topics Cryptology nowadays is one of the most important areas of applied mathematics building on deep results and methods from various areas of mathematics. This text is devoted to the study of stochastic aspects of cryptology. Besides classical topics from cryptology the author presents chapters on probabilistic prime number tests factorization with quantum computers random number generators pseudo random number generators information theory and the birthday paradox and meet in the middle attack. In the light of the vast literature on stochastic results relevant for cryptology this book is intended as an invitation and introduction for students researchers and practitioners to probabilistic and statistical issues in cryptology
