Internet of Things
The Internet of Things (IoT) offers great potential to design new or upgrade existing products for a wide range of applications. Not only commercial products will benefit from new IoT innovations, but also industrial applications and systems. Research topics of the Embedded Systems Lab are sensors and sensor networks, mobile devices, communication technologies, and smart textiles. Our aim is to transfer knowledge and research results to our cooperation partners, supporters and students.
Sensors and Sensor Networks
Today, sensors are integrated almost everywhere. The Embedded Systems Lab has profound experience with measurement and analysis of sensor data like pressure, temperature and humidity, acceleration and positioning, heart rate and heart rate variability, and electrical activity of muscles. Smart sensors with integrated signal processing and wireless communication interfaces will gain increasing importance within IoT systems. Another topic of the Embedded Systems Lab are sensor networks, wireless sensor networks, and the seamless transfer of sensor information from the sensor to the cloud.
IoT systems have diverse requirements on communication technologies, such as throughput, latency, real-time capabilities, seamless transitions, security, and wireless capability. Within the scope of various research projects we have implemented and/or used many different communication technologies, from low level bus systems (e.g. CAN, RS485, SPI) up to high level wireless communication technologies (e.g. Bluetooth, WiFi, ZigBee). The Embedded Research Lab specialized on Near Field Communication and Bluetooth Low Energy for low power embedded systems during the last years.
IoT applications have huge potential, but also significant dangers. The interconnection of all components of a system tremendously increases the risk of cyber-attacks and manipulations. Thus, the Embedded Systems Lab aims to analyze and develop efficient security mechanisms for embedded systems. We have gained profound experience with security applications using secure elements (SE) and trusted platform modules (TPM). Important topics are mutual authentication of devices, TPM/SE integration, secure user interfaces, and security of communications channels.
Mobile Devices and BYOD
Mobile devices like smartphones, tablets, or smartwatches are a gateway to the Internet of Things. They help us to seamlessly communicate with various other devices and systems, such as home automation, entertainment systems, or car systems. It will become common practice to access production processes in industrial facilities with “bring your own devices” (BYOD). BYOD will be used for the authentication, configuration and communication with IoT devices. A research focus of the Embedded Systems Lab is the secure integration of BYOD in critical applications.
