16-bit MSP430 Microcontroller Projects
ECC NIST P-192 on the MSP430 |
date: 01/09/2012 |
We present a cryptographic library for MSP430 microcontrollers that implements scalar multiplication using the NIST P-192 elliptic curve, a random number generator, and SHA-1. The implementation was tested on the WISP RFID tag (WISP4.1DL that is equipped with the 16-bit MSP430F2132).
Implementation details can be found in our paper (joint work with Christian Pendl and Markus Pelnar) or in our IGI Global book chapter Elliptic Curve Cryptography on WISPs.
Code size of the ECC library:
MSP430 without HW multiplier: 8,048 bytes
MSP430 with HW multiplier (low area, looping): 7,480 bytes
MSP430 with HW multiplier (high speed, unrolled): 16,060 bytes
SHA-1: 1,012 bytes
Random Number Generation (RNG, Marsaglia): 218 bytes
