摘要
A method of performing a keyed cryptographic operation by a cryptographic system mapping an encoded input message to an output message, including: receiving an encoding selection parameter p; receiving the encoded input message, wherein the encoding on the input message corresponds to the encoding selection parameter p; decoding the input message using an inverse of a default input encoding; computing a first portion of the cryptographic operation on the decoded input message to produce a first portion output; and compensating the first portion output based upon the encoding selection parameter p.
