Abstract:
A method of implementing a method of mapping an input message to an output message by a keyed cryptographic operation, wherein the keyed cryptographic operation includes a plurality of rounds using a Feistel network, including: receiving an input having a first half and a second half; performing, by a basic block, a portion of a round function on the second half to produce a portion of an encoded output, and wherein the basic block provides a portion of the second half as a portion of an encoded first input to a next round; and XORing the portion of the encoded output and a portion the first half to produce a portion of an encoded second input to the next round.
