摘要
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).
