SECURITY MECHANISM FOR EXTERNAL CODE

摘要

A method for providing a security mechanism for an external code, wherein the method includes receiving the external code comprising a request for a server specific bootstrapping key (Ks_NAF). The method further comprises determining a server identifier (NAF-Id) and a security token. Furthermore, the method comprises generating the server specific bootstrapping key (Ks_NAF) based on the server identifier (NAF-Id), and generating an external code specific bootstrapping key (Ks_js_NAF) using the server specific bootstrapping key (Ks_NAF) and the security token. The method also comprises using the external code specific bootstrapping key (Ks_js_NAF) for the security mechanism of the external code.
