    • Embodiments provide a means for securing wireless network communications. A security association can be established between a mobile subscriber device (105) and an access router (125) of a wireless communications network (120), upon successful authentication of the mobile subscriber device (105). The security association can utilize a dynamically-generated IP security (IPsec) symmetric key (175) unique to the mobile subscriber device (105). Subsequent network communications between the mobile subscriber device (105) and the access router (125) can be secured using the IPsec symmetric key (175) to either directly authenticate and encrypt/decrypt or dynamically establish further security associations to authenticate and encrypt/decrypt the subsequent network communications (170). Securing of the network communications (175) can be performed as a substitute for or in addition to existing security measures of the wireless communications network (120).
    • 实施例提供了一种用于确保无线网络通信的手段。 在移动用户设备(105)的成功认证之后,可以在无线通信网络(120)的移动用户设备(105)和接入路由器(125)之间建立安全关联。 安全关联可以利用移动用户设备(105)唯一的动态生成的IP安全(IPsec)对称密钥(175)。 可以使用IPsec对称密钥(175)来保护移动用户设备(105)和接入路由器(125)之间的后续网络通信,以便直接认证和加密/解密或动态地建立进一步的安全关联以认证和加密/解密 后续网络通信(170)。 可以执行网络通信(175)的保护作为对无线通信网络(120)的现有安全措施的替代或补充。
