TL;DR: This paper investigates physical obfuscation techniques, which perform alterations of circuit elements that are difficult or impossible for an adversary to observe, and provides a categorization of the available physical obfuscations as it pertains to various design stages.

TL;DR: A new efficient method to identify random delays in power measurements by using a string matching algorithm to find patterns of dummy operations and to align the power traces.

TL;DR: This work evaluates efficient implementations of standardized and/or well-known lightweight and hardware-friendly algorithms and presents IPSecco, a core with adequate security and only moderate resource requirements, making it suitable for lightweight devices.

TL;DR: This paper provides the first open-source gate-library agnostic framework for gate-level netlist analysis and demonstrates the workflow of the modular framework HAL on the basis of two case studies and provides profound insights on its technical foundations.

TL;DR: This work presents the first successful differential power analysis attacks on numerous commercially available products employing KeeLoq code hopping, and combines side-channel cryptanalysis with specific properties of the Kee Loq algorithm to efficiently reveal both the secret key of a remote transmitter and the manufacturer key stored in a receiver.
