Cryptography is a key technology in electronic key systems. It is used to keepdata secret digitally sign documents access control and so forth. Userstherefore should not only know how its techniques work but they must also beable to estimate their efficiency and security. Based on courses taught by theauthor this book explains the basic methods of modern cryptography. It iswritten for readers with only basic mathematical knowledge who are interestedin modern cryptographic algorithms and their mathematical foundation. Severalexercises are included following each chapter. This revised and extendededition includes new material on the AES encryption algorithm the SHA1 Hashalgorithm on secret sharing as well as updates in the chapters on factoringand discrete logarithms.
