One of the huge problems for security in sensor networks is the lack
of resources. Based on microcontroller architectures with severe
limited computing abilities, strong public-key cryptography is
commonly seen as infeasible on sensor devices. In contrast to this
prejudice this paper presents an efficient and lightweight
implementation of public-key cryptography algorithms relying on
elliptic curves. The code is running on Atmels popular 8Bit ATMEGA128
microcontroller, the heart of the MICA2 platform.
