摘要: The invention provides an establishment of a secret session key shared Between two network elements (NEa, NEb) belonging to different network domains (NDa, NDb). A first network element (NEa) of a first network domain (NDa) requests security parameters from an associated key management center (KMC) (AAAa). Upon reception of the request, the KMC (AAAa) generates a freshness token (FRESH) and calculates the session key (K) based on this token (FRESH) and a master key (KAB) shared with a second network domain (NDb). The security parameters are (securely) provided to the network element (NEa), which extracts the session key (K) and forwards the freshness token (FRESH) to the KMC (AAAb) of the second domain (NDb) through a second network element (NEb). Based on the token (FRESH) and the shared master key (KAB), the KMC (AAAb) generates a copy of the session key (K), which is (securely) provided to the second network element (NEb). The two network elements (NEa, NEb) now have shares the session key (K), enabling them to securely communicate with each other.
