Abstract
A method of encrypting or decrypting an input message block of binary data of predetermined length 2n into an output message block by dividing the message block into two equal size halves, performing one or more transformation rounds on the message block halves, each transformation round further comprising the steps of determining a key, processing the first half data block using a hash function to obtain a modified first half data block of length n, and combining the modified first half data block with the second half data block to obtain a modified second half data block of length n; and, lastly, appending the first modified half data block to the second modified half data block to obtain the output message block.
