TOKEN-BASED DISTRIBUTED GENERATION OF SECURITY KEYING MATERIAL |
摘要 |
A method and apparatus for delegating distribution of security keying material for the communication path between a mobile entity and a network service function, to the mobile entity. An authorization token is issued to the mobile entity which then supplies security keying material for the communication path. The keying material may be created by the Mobile entity itself. The mobile entity sends the security path material and the authorization token to a network service function. The network service function checks the authorization token to determine if the mobile entity is authorized to create the key material. If so, the received keying material is installed for use in securing the communication path with the mobile entity. The network service function may also be issued with a token to show that it is trusted by the issuer of the token. |
