The introduction of information and communication technologies to the traditional energy grid offers advantages like efficiency, increased reliability, resilience and better control of demand-response, while on the other hand poses customers' privacy at risk. Aggregation of electricity consumption readings in intermediate nodes is needed for efficient network utilisation; however, by using information...
With the evolution of the smart grid, most homes will be equipped with smart meters that support consumption reading, demand response and applications requiring two-way communications. In this context, security is a key aspect for smart grid adoption, especially since customers will have physical access to smart meters installed in their premises. Customers will be able to modify the software, firmware...
Anonymity on SIP signaling can be achieved either by the construction of a lower level tunnel (via the use of SSL or IPSec protocols) or by employing a custom-tailored solution. Unfortunately, the former category of solutions present significant impediments including the requirement for a PKI and the hop-by-hop fashioned protection, while the latter only concentrate on the application layer, thus...
The Session Initiation Protocol (SIP) is an application layer signaling protocol for the creation, modification and termination of multimedia sessions and VoIP calls with one or more participants. While SIP operates in highly dynamic environments, in the current version its authorization support is based on traditional access control models. The main problem these models face is that they were designed...
The dramatic increase in the use of Information and Communication Technologies (ICT) within Networked Critical Infrastructures (NCIs), e.g., the power grid, has lead to more efficient and flexible installations as well as new services and features, e.g., remote monitoring and control. Nevertheless, this has not only exposed NCIs to typical ICT systems attacks, but also to a new breed of cyber-physical...
The Session Initiation Protocol (SIP) is a signaling protocol for the creation, modification and termination of multimedia sessions with one or more participants. While SIP operates in highly dynamic environments such as Next Generation Networks, in current deployments its access control support is based on traditional access control models. The main problem these models face is that under certain...
