In this paper we present a secure and unclonable embedded system design that can target either an FPGA or an ASIC technology. The premise of the security is that the executed machine code and the executing environment (the embedded processor) will authenticate each other at a per-instruction basis using Physical Unclonable Functions (PUFs) that are built into the processor. The PUFs ensure that the...
This paper considers the problems of stability for continuous-time positive nonlinear systems with delay via T-S fuzzy modeling. Based on quadratic copositive Lyapunov-Krasovskii functions (QCLKFs) a simple sufficient condition of stabilityis is obtained, which is independent of the delay. Then, the proposed stability conditions are improved via high order relaxations in the QCLKF and its time derivative...
This paper addresses the stability problem for switched systems with time-varying delay and parametric uncertainties. The main idea is to construct new piecewise time-varying Lyapunov functionals/functions such that they are decreasing at switching time instants in spite of their discontinuity at those switching time instants. Then the constructed piecewise time-varying Lyapunov functionals/functions...
A cost effective, high speed and programmable true-time-delay optical beamformer based on recirculating loop with few nanoseconds beamsteering speed is proposed. This technique can drastically reduce number of components. Experimental results for proof-of-concept are presented.
