摘要：In this article we present a performance comparison of four symmetric block ciphers namely DES, Triple-DES, AES, and Blowfish. Performance evaluation based on CPU execution time is conducted under WinXP and Ubuntu /Linux version 8.10 operating system platforms. The study is conducted using Java programming language, Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE). The evaluation of the performance of these algorithms is done for encryption, decryption and key generation operations.
