手机病毒的分析及对策 摘要：目前手机的功能越来越丰富,已不再局限于通话,更多的功能被植入到手机中来。从聊天到手机上网,各种各样的资源开始涌入我们的手机。在此期间,手机病毒也就应运而生。随着3G时代的来临,接入互联网获取大量信息已成为手机的重要功能之一,这也相应地给手机感染病毒增加了机会。 但是无论是思想上的重视程度还是研究资金上的投资力度都远远落后与手机病毒的发展,大家对此似乎都呈一种观望的态度。为了更有效地对手机病毒进行防范,对手机病毒的研究已经刻不容缓。 本文首先对手机病毒的概念、类型、原理以及发展趋势等进行了介绍,然后列举了几个手机病毒的攻击实例,并就其中三种典型的手机病毒进行具体的分析,包括它们所造成影响、实现机理以及删除方法等。由于目前手机病毒主要通过短消息或上网下载Java小程序等方式感染病毒,因此我们又对短消息业务系统及Java小程序的安全风险进行了分析,并提出相应的对策。 关键词：手机病毒、趋势、特点、对策 Analysis and Countermeasure of mobile phone viruses Abstract：The function of the mobile phone is more and more abundant at present. It has already no longer confined to conversing. More functions have been planted into the mobile phone. From chatting to surfing in the Internet with mobile phone, various resources begin to pour into our mobile phone. During this period, the virus of the mobile phone arises at the historic moment too. With the arrival of 3G era, it is the one of the important functions of the mobile phone to be insertted into Internet and obtain a large number of information, and it increased the chance for the mobile phone to be infected with the virus too.But no matter the attention degree on the thought, or the dynamics of investment on the research fund, far lag behind the development with the virus of the mobile phone. Everybody seems to present a kind of attitude looked around to this. In order to take precautions against the virus of the mobile phone more effectively, the study on virus of the mobile phone has been already very urgent.Then enumerated the attack instances of several pieces of mobile phone virus, and carry concrete analysis on three kinds of typical mobile phone virus among them, including influence, realizing mechanism and deleting the method,etc. Because mobile phone infect with the virus through short news and a Java applet download from Internet, so we have analysed to the security risks of the business system of short news and a Java applet, and put forward the corresponding countermeasure.
