Abstract
A method or cryptographic system for communicating securely over an insecure communication channel of the type which communicates a message from a transmitter to a receiver includes the step of providing a finite filed serial-serial multiplication/reduction structure wherein an initial delay and clock-cycle are inherently independent of word length and wherein input operands are serially entered one digit at a time and the output result is computed serially one digit at a time, wherein the digit size can be one bit or more. As disclosed, the multiplication structure is scalable and a serial transfer reduces the bus width needed to transfer data back and forth between memory and a multiplication/reduction step. A finite field multiplication structure in which an operand multiplication and a finite field reduction are formulated as a serial-serial computation is also disclosed.
