Cryptography for practitioners. Protocols, algorithms and source programs in C language

The book is the second edition of a practical guide for the use of cryptography - an area dealing with data security in computer systems. Programmers and specialists in electronic communication will find detailed information on this subject. They learn about encryption and decryption techniques, as well as many cryptographic algorithms. They will learn how to implement them in the software and how to use them to effectively solve information security problems. This edition includes, inter alia, new developments related to the Clipper integrated circuit, including ways of neutralizing the key storage mechanism; new algorithms, including from the former Soviet Union and South Africa, and the RC4 stream cipher; the latest protocols of digital signatures, authentication, secure products, electronic money. An important part of the book are source programs in C language, in which cryptographic algorithms were used, and an impressive bibliography containing all the items relevant to contemporary cryptography.
The book is intended for IT students, as well as for IT professionals dealing with security and computer data protection.
