Description:
IoT (Internet of Things) technologies have recently gained growing interest from numerous industries, where devices, machines, sensors, or simply things are to be linked over open communication networks. However, such an operation environment brings new security threats and technology challenges in securing and stabilizing such large systems in the IoT world. Secured device identity in such an environment is an essential requirement to serve as security anchor for most applications towards clone-resistant, resilient and operational security. Therefore, physically unclonable units emerge as an essential requirement to serve as such security anchors for diverse IoT systems. Analogous Physical(ly) Unclonable Functions (PUFs) were proposed as unclonable structures two decades ago. However, all traditionally proposed PUFs are analog and suffer from a lack of reproduction-stability due to aging effects and inconsistencies associated with varying operating and environmental conditions, such as supply voltage and temperature. To counteract the inherent inconsistency of analog PUFs, complex fuzzy extractors with significant extra data storage and complex error correction algorithms have been employed. Unfortunately, this made the deployment of PUFs in practice highly complex and costly for mass products. This thesis presents the new concept of creating Secret Unknown Ciphers SUCs in SoC FPGAs as alternative to PUFs. Several sample use cases of SUC in diverse industrial applications such as vehicular, medical devices and medical security environment are presented together with possible corresponding SUC-based security protocols. The thesis addresses first a comparative analysis between the contemporary clonable solutions for identifying connected devices in IoT environment and those unclonable solutions as PUF- and SUC-based techniques. Second, SUC-based sample automotive applications are developed and presented with their corresponding use-case scenarios and security protocols. The third part is on developing SUC-based ...
