Abstract

Maximizing the battery lifetime of wireless sensor nodes and equipping them with elliptic curve cryptography is a challenge that requires new energy-saving architectures. In this paper, we present an architecture that drops a hardware accelerator between CPU and RAM. Thus neither the CPU nor the data memory need to be modified. In a detailed comparison with a software-only and a dedicated hardware architecture, we show that the drop-in concept is smaller than the dedicated hardware module, while achieving similarly fast runtimes. Most interesting for micro-chip manufacturers is that only 4 kGE of chip area need to be committed for the dedicated drop-in accelerator.
