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

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 ...

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.

Evolving intelligent interexchange network-an SS7 perspective
Proceedings of the IEEE, 1992The role of common channel signaling, referred to as Signaling System No.7 (SS7), in the evolution of services in an interexchange carrier environment is discussed. The importance of SS7 in evolving the intelligent network necessary to support these services is addressed.

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.

Simulation of SS7 common channel signaling
IEEE Communications Magazine, 1994Simulating trunk and signaling networks allows planners to examine network survivability, capacity, and the impact of new service introductions. The challenge is to accurately predict network performance and behavior for a rapidly changing environment, and for the very large networks that are encountered in the public telephone system.

A scalable and reusable emulator for evaluating the performance of SS7 networks
IEEE Journal on Selected Areas in Communications, 1994A scalable and reusable emulator was designed and implemented for studying the behavior of SS7 networks. The emulator design was largely based on public domain software. It was developed on top of an environment supported by PVM, the Parallel Virtual Machine, and managed by OSIMIS/spl minus/the OSI Management Information Service platform.

Multi-protocol authentication for SIP/SS7 mobile network
Computer Communications, 2008The communication paradigm has rapidly shifted from wireless mobile networks to All-Internet Protocol (IP) networks such as Multimedia Sub-system (IMS), Multi-Media Domain (MMD), and Worldwide Interoperability for Microwave Access (WiMAX), led by service industry leaders and communication manufacturers.

MTPSec: Customizable Secure MTP3 Tunnels in the SS7 Network
19th IEEE International Parallel and Distributed Processing Symposium, 2005The signaling system 7 (SS7) is the control network used by public telephones all over the world. Having been designed in an era where few large companies controlled the entire network, SS7 has virtually no security. Due to telecommunication deregulation, liberalization of economies and the convergence of telephone, IP and wireless networks, interfaces
