PKI技术在5G网络中的应用挑战及应对

Challenges and countermeasures of PKI technology in 5G networks

随着移动互联网的发展,PKI作为网络身份认证的重要技术方案,在移动通信网络中产生了巨大的应用空间。然而,以5G为代表的新一代移动通信网络具有设备规模庞大、复杂程度较高、重要级别凸显和影响范围广泛等特点,给PKI电子认证的普遍应用带来巨大挑战。为了使PKI技术更好地服务于5G网络,同时避免因证书管理等问题带来的安全隐患和影响,本文分别分析了5G网络中PKI技术的应用场景及面临挑战,并根据应用场景的特点和规范要求,从证书标识、主体认证、证书类型和证书管理等方面提出了相应的安全应对建议。

With the rapid development of mobile internet,PKI has great potential in development and application.However,the new generation mobile network such as 5G,has the characteristics of large equipment scale high complexity,prominent important level and wide infl uence range,which brings great challenges to the universal application of PKI electronic authentication.In order to make PKI technology serve the 5G networks and avoid the security risks and impacts caused by certificate management,the application scenarios and challenges of PKI in the 5G networks are analyzed respectably.According to the characteristics and specification requirements of the scenarios,the security suggestions of certificate identification,subject authentication,certifi cate profi le and certifi cate management are proposed.
