        This report presents a preliminary analysis of the security offered by
        the RC6$^{TM}$ block cipher. RC6 is an evolutionary improvement of RC5,
        designed to meet the requirements of the Advanced Encryption Standard
        (AES). Our analysis demonstrates that RC6 is highly resistant to differential
        and linear cryptanalytic attack, which are currently the two most
        effective analytical attacks on block ciphers. The data requirements to
        mount an attack using either of these two attacks exceeds the amount of
        available data with considerable margins for safety.
