目前,随着4G时代的到来和移动终端设备的不断普及,人们的生活方式有了很大的改变,但是随之而来的安全问题也在增加,黑客可以利用智能终端通过远程视频、地理位置等监控受害者,垃圾短信、恶意插件、二维码等充斥着整个智能终端市场,高传输速率、复杂的4G移动网络使用户存储在终端上的隐私信息更容易被不法分子窃取,本文针对这些问题首先分析了4G的基本特征,然后从应用、网络、终端三个方面介绍了4G所面临的安全挑战,最后针对这些安全挑战提出了相应的应对策略。
At present, with the advent of the 4G era and the continuous popularization of mobile terminal devices, people’s lifestyles have undergone great changes, but the ensuing security problems are also increasing. Hackers can use the smart terminal to remotely access the video and the geographic location Such as monitoring victims, spam, malicious plug-ins, two-dimensional code is flooded with the entire smart terminal market, high transmission rate, complex 4G mobile network allows users to store private information on the terminal easier to be stolen by lawless elements, The problem first analyzes the basic features of 4G, and then introduces the security challenges faced by 4G from three aspects of application, network and terminal. Finally, we put forward corresponding countermeasures for these security challenges.
