Attacks on cryptosystem implementations (e.g. security fault injection, timing analysis and differential power analysis) are amongst the most exciting developments in cryptanalysis of the past decade. Altering the internal state of a cryptosystem or profiling the system’s computational dynamics can be used to gain a huge amount of information. This paper shows how fault injection and timing ana...

Abstract Measuring soil health indicators (SHIs), particularly total nitrogen (TN), is an important and challenging task that affects farmers’ decisions on timing, placement, quantity of fertilizers applied in the farms. Most existing methods to measure SHIs are in-lab wet chemistry or spectroscopy-based methods, which require significant human input effort, time-consuming, costly, low-throughp...

In this paper, we present a new method for verifying the realizability of a timing diagram with linear timing constraints, thus ensuring that the implementation of the underlying interface is feasible. The method is based on the consistency of the timing constraints derived from the timing diagram and accepts unknown occurrence times for events produced by the environment.

This work introduces capacity limits for molecular timing (MT) channels, where information is modulated on the release timing of small information particles, and decoded from the time of arrival at the receiver. It is shown that the random time of arrival can be represented as an additive noise channel, and for the diffusion-based MT (DBMT) channel this noise is distributed according to the Lév...

Post-silicon tuning is attracting a lot of attention for coping with increasing process variation. However, its tuning cost via testing is still a crucial problem. In this paper, we propose tuning-friendly body bias clustering with multiple bias voltages. The proposed method provides a small set of compensation levels so that the speed and leakage current vary monotonically according to the lev...

Experiments were conducted to evaluate the performance of a high grade low heat rejection (LHR) diesel engine with air gap insulated piston, air gap insulated liner and ceramic coated cylinder head [ceramic coating of thickness 500 microns was done on inside portion of cylinder head] with different operating conditions [normal temperature and pre-heated temperature] of crude pongamia oil (CPO) ...

In this paper we address the parallel timing simulation of synchronous VLSI designs on a network of workstations (NOWs). We suggest combining cycle based and conventional timing simulation techniques to achieve fast timing simulation even on NOWs which are typically characterized by low bandwidth and high communication latency. In particular we execute a timing simulator on each node of the NOW...
