Implementação em Software de Criptografia Assimétrica para Redes de Sensores com o Microcontrolador MSP430

Conrado P. L. GouvêaJulio López

We describe a software implementation of Elliptic Curve Cryptography (ECC) and Pairing-Based Cryptography for the MSP430 microcontroller family, which is used in sensors such as the Tmote Sky, TelosB and TinyNode. The ECDSA digital signature protocol for ECC and the NIKDP non-interactive key distribution protocol for PBC were implemented on the 80 and 128-bit levels of security, using binary and prime fields. We have obtained a pairing computation that is 21% to 28% faster due to a new optimization for modular reduction in prime fields and an efficient binary field implementation.
