Security on IoT Devices with Secure Elements
The emergence of new low power IoT networks in which leaf nodes have native IPv6 connectivity and the grown awareness for data protection of IoT devices requires leaf nodes to provide a higher level of security, similar to the level of a standard computer system. Especially in terms of energy consumption and device cost, the intensive cryptographic operations of well-known computer security algorithms are a big challenge for resource constrained devices. To face these challenges, semiconductor vendors have recently introduced new dedicated hardware, so called secure elements. These devices provide hardware accelerated support for cryptographic operations and tamper proof memory for the secure storage of cryptographically sensitive material. Moreover, they employ specific techniques against so-called side channel attacks. The paper describes and specifies different classes of secure elements and provides support to select a fitting secure element for a targeted application. Four selected secure elements from different vendors have been measured and analyzed in terms of energy consumption and execution time, providing performance indications and allowing a quantitative comparison. Application in two distinct real world use cases reveals strengths and weaknesses of the individual secure elements. The presented quantitative and qualitative results serve as a starting point for developers employing secure elements to increase security on their IoT devices.
