Implementation of Elliptic Curve Diffie Hellman in ultra-low power microcontroller

In this article, the ECDH crypto library is introduced. This library is designed to ultra-low power MSP430 microcontroller and it allows implement time and memory consuming cryptographic operations in this microcontroller with limited resources. The main part of the article focuses on the way of ECDH implementation to the MSP430 microcontroller. Some implementation problems were discussed here. The practical part of the article focuses on measuring of computing times and memory size requirements. Our solution of ECDH crypto library allows the use of public key cryptography for key establishment for microcontroller with limited resources without adding any additional specialized equipment.
