Telecommunication System Security
Telecommunication systems have evolved significantly and rapidly in recent years. Since much of the evolution has been pushed by customer demand for higher quality and faster data rates, service providers have often overlooked threats and vulnerabilities in their system designs in favor of faster response to customer needs. In an effort to push for more reliable and resilient telecommunications, we have studied a number of such threats and vulnerabilities that can be addressed using practical techniques that do not incur significant overhead or modification to production systems. At a more fundamental level, we are also investigating deeper redesign of the telecommunication infrastructure to study alternatives that could drastically improve service quality to users, costs to service providers, and capabilities for all parties.
