Abstract :
This paper presents a microcode instruction set coprocessor which is designed to work with an 8-bit 8051 microcontroller and implements a hyperelliptic curve cryptosystem (HECC). The microcode coprocessor is capable of performing a range of Galois field operations using a dual-multiplier/dual-adder datapath and storing the intermediate results in the local storage unit of the coprocessor (RAM). This coprocessor is programmed using the software routines from the 8051 microcontroller which implements the HECC divisor´s doubling and addition operations. The Jacobian scalar multiplication was computed in a 656 msec (7.87 M cycles) at 12 MHz clock frequency.
