METHOD AND APPARATUS FOR INCREASING THE SPEED OF CRYPTOGRAPHIC PROCESSING
摘要
<p>Encrypting data in as cascaded block cipher system may be accomplished by applying a first encryption algorithm using a secret shared between first and second parties as a key to generate a secret inner key; applying a second encryption algorithm for a predetermined number of rounds using the secret inner key to generate a plurality of blocks of ciphertext data from a plurality of blocks of plaintext data; and repeating the applying the first encryption algorithm and the applying the second encryption algorithm steps.</p>
