Exploiting the weaknesses of SS7
Network Security, 2017For many telecoms service providers, the migration to an IP-only network is a major focus and an on-going process. In parallel with this evolution, most service providers understand the need to support traditional Signalling System No.7 (SS7) and SIGTRAN protocols for the foreseeable future. With the buzz of 5G, it's easy to underestimate the relevance

VLSI implementation of the SS7 TCAP
2nd International Conference on ASIC, 2002The Transaction Capabilities Application Part (TCAP) is the most recent addition to the Signaling System Number 7 (SS7), an open-ended common channel signaling standard that can be used over a variety of digital circuit-switched networks, in particular, ISDN.

The implementation of SS7 in JSU-16000
Proceedings of International Conference on Communication Technology. ICCT '96, 2002An important aspect in the development of communication networks is the development of signalling technology. SS7 is a common channel signalling system recommended by CCITT, which is adapted to the development of ISDN and IN. This paper presents a general scheme to implement SS7 in JSU-16000, a fully distributed control digital switching system, that ...

SS7 over IP: signaling interworking vulnerabilities
IEEE Network, 2006Public telephony - the preferred choice for two-way voice communication over a long time - has enjoyed remarkable popularity for providing acceptable voice quality with negligible connection delays, perhaps due to its circuit-switched heritage. Recently, IP telephony, a packet-based telephone service that runs as an application over the IP protocol ...

Better Protection of SS7 Networks with Machine Learning
2016 6th International Conference on IT Convergence and Security (ICITCS), 2016Deregulation and migration to IP have made SS7 vulnerable to serious attacks such as location tracking of subscribers, interception of calls and SMS, fraud, and denial of services. Unfortunately, current protection measures such as firewalls, filters, and blacklists are not able to provide adequate protection of SS7.

SS7 network management using link monitors
Proceedings of ICC'97 - International Conference on Communications, 2002The disruption and loss of SS7 signalling networks during the summer of 1991 in North America by the "brown outs" and the resultant loss of services, revenue and customers, has focused the minds of many Telcos to put management systems in place to ensure network robustness.
