摘要
It is shown that synchronous stream ciphers based on keystream generators can be used for efficient and secure encryption/decryption of random access files if the underlying next-state function satisfies an associativity condition. In particular, secure designs based on combining different types of linearity in the next-state function are proposed. (C) 1999 Elsevier Science B.V. All rights reserved.
