Power consumption evaluation of efficient digital signature schemes for low power devices
Stefaan Seys, Bart Preneel · 2006
In this paper we evaluate the power consumption of different digital signature schemes. We compare the cost of the elliptic curve digital signature algorithm with signature schemes solely based on symmetric techniques such as the Diffie-Lamport one-time signature scheme. These evaluations take into account all aspects of using digital signatures in wireless environments: energy consumption of key generation, signing and verification, and the communication cost of sending and receiving the necessary data (including the public keys and the necessary data to authenticate them).
