摘要:
 随着现代信息安全和无线通信技术的高速发展,对于有广泛数据业务量的5G移动通信系统来说,将会有大量的机密、敏感信息在其通信系统中进行传输,所以安全问题越来越引起人们的关注,提供安全传输服务显得尤为重要.随着计算机不断增强的计算能力,传统的基于计算复杂度的加解密算法和密钥协商机制已经不能满足人们对于未来无线通信安全性的要求,而基于信号调制的方向调制技术因其无需考虑窃听者的计算能力,通过扰乱非期望方向上的信号星座图来实现安全传输的目的,成为了5G系统的重要研究点.在简单介绍了波束赋形的原理及其不足的基础上引出方向调制技术,并着重阐述了在大规模天线阵的前提下,基于天线子集选择和混合阵的方向调制技术实现安全传输目标的方法,并且从理论的角度说明了安全性能的提高.
Abstract:
 With the rapid development of modern information security and wireless communication technology,more and more people have paid attention to the security of sensitive information in the transmission process.It is particularly important to focus on secure services for 5G mobile systems,which is faced with a wide range of data traffic.With the increasing computing ability of the computer,the traditional encryption and decryption algorithm based on the computational complexity and the secret key negotiation mechanism has been unable to meet the requirements of wireless communication security in future.However,because directional modulation technique based on signal modulation can distort the signal constellation in undesired direction without considering the computer ability of the eavesdroppers,it is becoming a important hotspot in 5G system.Simply introducing the principle and shortcomings of technique,it is demonstrated that how the directional modulation technique based on antenna selection and mixed array achieve the goal of safe transmission under the premise of the large scale antenna array,and that the improvement of safety performance from the theory is validated.
