IDENTIFICATION INFORMATION PROTECTION METHOD IN WLAN INTERCONNECTION |
摘要 |
By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user' s home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN. <IMAGE> |
