Cryptographic Algorithms: Basic Concepts and Applications to Multimedia Security
Bart Preneel, M. Csapody, Joos P. L. Vandewalle · 1997
This paper provides an overview of the state of the art in the design of cryptographic algorithms and discusses the protection of multimedia information as an example. It re-views the di®erent type of algorithms for encryption and authentication. The principles are explained of stream ciphers, block ciphers, hash functions, public-key encryption algo-rithms, and digital signature schemes. Subsequently the design and evaluation procedures for cryptographic algorithms are discussed. 1
