Securing Information-Centric Networking without negating Middleboxes
Information-Centric Networking is a promising networking paradigm that
overcomes many of the limitations of current networking architectures. Various
research efforts investigate solutions for securing ICN. Nevertheless, most of
these solutions relax security requirements in favor of network performance. In
particular, they weaken end-user privacy and the architecture's tolerance to
security breaches in order to support middleboxes that offer services such as
caching and content replication. In this paper, we adapt TLS, a widely used
security standard, to an ICN context. We design solutions that allow session
reuse and migration among multiple stakeholders and we propose an extension
that allows authorized middleboxes to lawfully and transparently intercept
secured communications.Comment: 8th IFIP International Conference on New Technologies, Mobility &

CoAP over ICN
The Constrained Application Protocol (CoAP) is a specialized Web transfer
protocol for resource-oriented applications intended to run on constrained
devices, typically part of the Internet of Things. In this paper we leverage
Information-Centric Networking (ICN), deployed within the domain of a network
provider that interconnects, in addition to other terminals, CoAP endpoints in
order to provide enhanced CoAP services. We present various CoAP-specific
communication scenarios and discuss how ICN can provide benefits to both
network providers and CoAP applications, even though the latter are not aware
of the existence of ICN. In particular, the use of ICN results in smaller state
management complexity at CoAP endpoints, simpler implementation at CoAP
endpoints, and less communication overhead in the network.Comment: Proc. of the 8th IFIP International Conference on New Technologies,

NDN, CoAP, and MQTT: A Comparative Measurement Study in the IoT
This paper takes a comprehensive view on the protocol stacks that are under
debate for a future Internet of Things (IoT). It addresses the holistic
question of which solution is beneficial for common IoT use cases. We deploy
NDN and the two popular IP-based application protocols, CoAP and MQTT, in its
different variants on a large-scale IoT testbed in single- and multi-hop
scenarios. We analyze the use cases of scheduled periodic and unscheduled
traffic under varying loads. Our findings indicate that (a) NDN admits the most
resource-friendly deployment on nodes, and (b) shows superior robustness and
resilience in multi-hop scenarios, while (c) the IP protocols operate at less
overhead and higher speed in single-hop deployments. Most strikingly we find
that NDN-based protocols are in significantly better flow balance than the
UDP-based IP protocols and require less corrective actions
