SYSTEM AND METHOD FOR GENERATING ROUND KEYS

摘要

A system and method for generating round keys used for encrypting and decrypting an input text block. A received cipher key is used to generate round keys that include round key words. Two round key words are generated at the same timebased on the word lengths of the input text block and the cipher key. The generation of round keys may be paused depending on the word lengths of the input text block and the cipher key.
