About this document
Stream Ciphers and Block Operations by Francesco Pistolesi is a document available to read on EtoBox.
This document discusses stream ciphers and block ciphers. It describes how stream ciphers operate on a bit-by-bit or block-by-block basis using a keystream generated from a secret key. Block ciphers like DES, AES and IDEA encrypt fixed-length blocks and are described in terms of their round structure and transformations. Modes of operation for block ciphers like ECB, CBC, CFB and OFB are also covered. Applications to GSM security including the A3 authentication, A5 encryption and A8 key generation algorithm
