Crypto for Tiny Objects
David J. Malan, David Malan · 2004
This work presents the first known implementation of elliptic curve cryptography for sensor networks, motivated by those networks' need for an e#cient, secure mechanism for shared cryptographic keys' distribution and redistribution among nodes. Through instrumentation of UC Berkeley's TinyOS, this work demonstrates that secret-key cryptography is already viable on the MICA2 mote. Through analyses of another's implementation of modular exponentiation and of its own implementation of elliptic curves, this work concludes that public-key infrastructure may also be tractable in 4 kilobytes of primary memory on this 8-bit, 7.3828-MHz device.
