On Detecting Relay Attacks on RFID Systems Using Qubits

As RFID technology is being widely used in access control systems to identify and track both objects and people, relay attacks on RFID systems continue to pose serious threats to security. To mitigate relay attacks, distance bounding protocols can be used. Until recently, all distance bounding protocols were based on classical cryptography and communication techniques. In this paper, we take a closer look at a recently proposed protocol by Jannati and Ardeshir-Larijani [Quantum Information Processing 2016, 18] to detect relay attacks using qubits. We first observe that the protocol has a weakness which allows an adversary to mount a successful attack on the protocol. We then propose a countermeasure to restore security and compare the fixed protocol with the state of the art.

Device Technology

AbstractState of the art CMOS devices have been scaled to such dimensions that we need take atomistic approach to understand their operation for nano-electronics. From a bottoms-up perspective, the smallest functional element within a nano-device would be a single (dopant) atom itself. Control and understanding of the eigenenergies and wavefunctions of a single dopant in Si is a key ingredient for device technology beyond-CMOS like quantum-information processing. Here, we will discuss the eigenlevels of a single As donor in a three terminal configuration. The donor is incorporated in the channel of prototype transistors called FinFETs. The measured eigenlevels are shown to consist of levels associated with the donors Coulomb potential, levels associated with a triangular well at the gate interface and hybridized combinations of the two. The theoretical framework in which we describe this system (NEMO-3D) is based on a tight-binding approximation.
