We propose a built-in scheme for generating all patterns of a given deterministic test set T. The scheme is based on grouping the columns of T, so that in each group of columns the number ri of unique representatives (row subvectors) as well as their product R over all such groups is kept at a minimum. The representatives of each group (segment) are then generated by a small finite state machine (FSM)...
Encryption algorithms could suffer fault injection attacks in order to obtain the secret key. In this paper, a specific protection for any round-based encryption algorithm is presented, analyzed and tested. It is providing a high degree of robustness together with a small penalty in the algorithm throughput when dealing with specific intentional attacks. Experimental results on advanced encryption...
This paper studies the impact of intra-die random variability on low-power digital circuit designs, specifically, circuit timing failures due to intra-die variability. We identify a new low-Vdd statistical failure mode that is strongly supply-voltage dependent and also introduce a simple yet novel method for quantifying the effects of process variability on digital timing - a delay overlapping stage...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
