Mobile Devices as Secure eID Reader using Trusted Execution Environments

Abstract

This work presents a prototype implementation of a smartphone as secure eID reader using NFC technology. The presented approach aims to reach a security level close to standalone smart card readers. This security level will be allowed by the means of a trusted execution environment (TEE) which allows strong isolation and separation for critical applications and provides trusted, not interceptable user input and output. The prototype supports the German eID (nPA) and follows the relevant guidelines.
