摘要
随着网络攻击日益频繁,传统网络防御技术已经无法满足当前需求。主动防御凭借其动态随机的特性,成为当前应对网络攻击的有效方法之一。端信息完全跳扩混合技术是一种主动防御技术,通过动态随机地调整端信息,使系统在端口关闭的情况下仍能保持通信,从而具有良好的隐蔽性和安全性。然而,该技术在传输速率和用户容量方面存在不足,仅支持一对一通信。为了解决上述问题,提出了一种新的网络通信策略,即将端信息完全跳扩混合技术和稀疏码分多址接入(sparse code multiple access,SCMA)相结合,以提高系统的接入用户容量和整体传输速率。理论分析和实验结果表明,在保证良好的隐蔽性和安全性情况下,该策略提高了系统的用户数量和传输速率。
As network attacks become increasingly frequent,traditional network defense technologies can no longer meet current demands.Active defense,relying on its dynamic and random characteristics,has become one of the effective methods to counter network attacks.The end-point information hopping and spreading hybrid technology is a type of active defense that,based on dynamically and randomly changing end-point information,allows the system to maintain communication even when ports are closed,thus providing excellent concealment and security.However,it has limitations in terms of transmission rate and user capacity,supporting only one-to-one communication.To address these issues,a new network communication strategy was proposed,which combined the end-point information hopping and spreading hybrid technology with sparse code multiple access(SCMA)to enhance the number of systemaccessible users and overall transmission rate.Theoretical analysis and experimental results show that the system's user capacity and transmission rate have been improved while ensuring good concealment and security.
