HTML5's New Features and Related Security Issues

HTML5,as new-generation standard for building Web applications,contains so many exciting features,such as completely-new label format,improved communication mechanism,local storage,offline app and multi-thread support.These features are designed in accordance with the trend of network application evolution,and could satisfy the requirements of software as a service used in cloud computing,thus allowing users to acquire a more dynamic and friendly content presentation.However,the lacking of sufficient maturity for core technologies in HTML5 leads to several runtime security problems,and such attacks as network fraud,malicious code and DoS could not be radically eliminated.Industrial entities have actively carried out corresponding research on security issues of HTML5,thus to make it more reliable and controllable,so that practical deployment could be realized as soon as possible.Here by analyzing the new features of HTML5,a threat model of the standard is concluded,and a series of security enhancement ideas are proposed as well.
