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...
Web is becoming a programmable platform, with countless services blooming everyday in various forms like Feeds, REST APIs and Widgets, etc. Although the existing technologies, such as Mashups, have reduced the challenges to build new applications by composing these services, it's still far from enabling the non-technical users to solve their situational problems by correlating and consuming these...
University students have been the most important online consumer group. Accordingly, this research intends to build up a university student behavioral intention model originally based on technology acceptance model (TAM), to explore the contributing factors of intention of online shopping and their interactive relationships. We conducted sampling survey of students from Guangzhou Higher Education...
It is well known that Web users create links with different intentions. However, a key question, which is not well studied, is how to categorize the links and how to quantify the strength of the influence of a Web page on another if there is a link between the two linked Web pages. In this paper, we focus on the problem of link semantics analysis, and propose a novel supervised learning approach to...
In the digital multimedia era, it is becoming increasingly important to ensure the integrity and authenticity of the enormous amount of the video data. To detect the effect of frame-deletion, which is one of the common and simple forgery methods in video streams, a new approach based on motion-compensated edge artifact is proposed in this paper. It introduces the factor of motion-compensated edge...
Recognition distance in urban space is affected by many factors. Based on the relevant factors, this paper sums up those which affect urban distance cognition in the travel mode of bus, and conducts a cognitive test to get people's recognition data. We make some quantitative analysis of these data in the use of statistical methods. The results show that: in the bus travel mode, recognition distance...
