HTML5是未来移动互联网的核心平台,更是未来移动互联网时代的技术制高点,但是它目前还没有成为W3C正式的推荐标准。这是因为首先HTML5在音视频标准上存在多版本,其次HTML5的专利风险使它的产业化前景出现了一定的不确定因素,再次,HTML5的Web存储中存在版权风险,最后,HTML5目前还无法通过技术措施实施数字版权管理。尽管HTML5的标准化进程存在着一些不确定性,但其很可能打破目前应用商店为主的移动互联网商业模式,并为中国ICT企业提供巨大的产业机遇和挑战。 相似文献

Based on over 900 million HTTP requests from an ISP backbone network,the HTTP characteristic of different content types from a wide range of perspectives was analyzed,including request composition,size,popularity and temporal dynamics,and an application-aware backbone network cache method was proposed,referred to as AACM.The experiment results show that in the case of a slight increase in cache space,the hit ratio of the online-video increases 15%, and the total source traffic and cache I/O load reduced by about half. 相似文献

The last version of Web’s hypertext standard has been developed from 2004 to 2014. During this era, HTML5 has experienced different crossroads due to the variety of motivations and needs that the main stakeholders interested in its development had. On October 2014, the standard got official by the W3C and closed a period of uncertainty around the future of the Web but at the same time, this agreement also introduced a major change in the own conception of the hypertext’s standard. In this paper we review the current status of digital commons on the Web and the development of HTML5. We also confront this analysis with several semi-structured interviews carried out with different experts in web development that represent at the same time different players of Web’s value chain.We argue that the development of HTML5 represents a new digital commons that prevented the proliferation of proprietary software that took place during the “Web 2.0” period. We claim that the World Wide Web promotes the development of new digital commons due to its own basis as a non-proprietary socio-technological platform. We also conclude that the development of standards and non-proprietary digital technologies is of outmost importance for the future of web business models that are fueled by major digital players. 相似文献

Over past few decades, various ways have been conducted through side channel attacks to steal information for a computer system. Unlike conventional hardware-based methods, i.e. power-based side channel, side channel on micro-architecture does not require any physical access to the devices under interest. Instead, only compromised programs need to be co-located on the same machine as the victim. For some other scenarios, malicious users can form side channel information leveraging the timing of program execution. In this survey, we are presenting a comprehensive taxonomy of attack vectors in stack cache memory modules, which mostly are the points of attack by side channel. Due to the significance of side channel attacks, the challenges and overheads of these attack vectors are described through the course of this study. We discuss what side channel attacks are, how they are used, and how they can be prevented through the use of obfuscation techniques. To accomplish this, we introduce the findings of a number of relevant works. These include successful attacks on systems using novel variations of side channel attacks and preventative measures against the attacks. 相似文献
