CryptoCoP: Lightweight, Energy-efficient Encryption and Privacy for Wearable Devices

Abstract

As people use and interact with more and more wearables and IoT-enabled devices, their private information is being exposed without any privacy protections. However, the limited capabilities of IoT devices makes implementing robust privacy protections challenging. In response, we present CryptoCoP, an energy-efficient, content agnostic privacy and encryption protocol for IoT devices. Eavesdroppers cannot snoop on data protected by CryptoCoP or track users via their IoT devices. We evaluate CryptoCoP and show that the performance and energy overheads are viable in a wide variety of situations, and can be modified to trade off forward secrecy and energy consumption against required key storage on the device.
