The project additionally prototypes the SS7 and Diameter signalling message protection, which is providing the message authenticity, integrity and confidentiality protection. This could be used by mobile operators to further secure their inter-PLMN interconnects against various active or passive signalling attacks.
The Diameter protection model was closely followed and further developed within GSMA DESS group. And the similar security mechanism was requested there from 3GPP for 5G networks (Liaison Statements S3-173407, S3-173433) - after the SEPP and the protected N32 interface became part of 5G networks.
