PRESENT, proposed by A. Bogdanov et al. in CHES 2007, is an ultra-lightweight symmetric cipher for extremely constrained environments such as RFID tags and sensor networks. In this article, a representative platform, 0.25 μm 1.8 V standard cell circuit is proposed to complement the PRESENT, the simulation-based ASIC experimental environment is built to acquire power data. According to the fact that...
In order to meet the educating and training requirements of tactical communication network (TCN), one advanced means is to develop its simulative training system. Firstly, the general framework of TCN simulative training system was designed, which included the system constitution, software structure and application manner. Secondly, a single federation and multi federation architecture were proposed,...
Hyphantria cunea is one of the harmful international plant quarantine pests. In order to monitor and control the increasingly serious situation, based on the materials and data collected by “the 221 project” in Beijing in recent three years, this paper studies the spatial decision-making system of hyphantria prevention and control simulation, by combining WebGIS, JSP and Ajax technology. We design...
