Protector Control PC-AODV-BH in The Ad Hoc Networks
In this paper we deal with the protector control that which we used to secure
AODV routing protocol in Ad Hoc networks. The considered system can be
vulnerable to several attacks because of mobility and absence of
infrastructure. While the disturbance is assumed to be of the black hole type,
we purpose a control named "PC-AODV-BH" in order to neutralize the effects of
malicious nodes. Such a protocol is obtained by coupling hash functions,
digital signatures and fidelity concept. An implementation under NS2 simulator
will be given to compare our proposed approach with SAODV protocol, basing on
three performance metrics and taking into account the number of black hole
malicious nodesComment: submit 15 pages, 19 figures, 1 table, Journal Indexing team, AIRCC

Practical challenges in quantum key distribution
Quantum key distribution (QKD) promises unconditional security in data
communication and is currently being deployed in commercial applications.
Nonetheless, before QKD can be widely adopted, it faces a number of important
challenges such as secret key rate, distance, size, cost and practical
security. Here, we survey those key challenges and the approaches that are
currently being taken to address them.Comment: To appear in npj Quantum Informatio
The Road Ahead for Networking: A Survey on ICN-IP Coexistence Solutions
In recent years, the current Internet has experienced an unexpected paradigm
shift in the usage model, which has pushed researchers towards the design of
the Information-Centric Networking (ICN) paradigm as a possible replacement of
the existing architecture. Even though both Academia and Industry have
investigated the feasibility and effectiveness of ICN, achieving the complete
replacement of the Internet Protocol (IP) is a challenging task.
Some research groups have already addressed the coexistence by designing
their own architectures, but none of those is the final solution to move
towards the future Internet considering the unaltered state of the networking.
To design such architecture, the research community needs now a comprehensive
overview of the existing solutions that have so far addressed the coexistence.
The purpose of this paper is to reach this goal by providing the first
comprehensive survey and classification of the coexistence architectures
according to their features (i.e., deployment approach, deployment scenarios,
addressed coexistence requirements and architecture or technology used) and
evaluation parameters (i.e., challenges emerging during the deployment and the
runtime behaviour of an architecture). We believe that this paper will finally
fill the gap required for moving towards the design of the final coexistence
architecture.Comment: 23 pages, 16 figures, 3 table
A Novel Approach to Transport-Layer Security for Spacecraft Constellations
Spacecraft constellations seek to provide transformational services from increased environmental awareness to reduced-latency international finance. This connected future requires trusted communications. Transport-layer security models presume link characteristics and encapsulation techniques that may not be sustainable in a networked constellation. Emerging transport layer protocols for space communications enable new transport security protocols that may provide a pragmatic alternative to deploying Internet security mechanisms in space. The Bundle Protocol (BP) and Bundle Protocol Security (BPSec) protocol have been designed to provide such an alternative.
BP is a store-and-forward alternative to IP that carries session information as secondary headers. BPSec uses BP’s featureful secondary header mechanism to hold security information and security results. In doing so, BPSec provides an in-packet augmentation alternative to security by encapsulation. BPSec enables features such as security-at-rest, separate encryption/signing of individual protocol headers, and the ability to add secondary headers and secure them at waypoints in the network. These features provided by BPSec change the system trades associated with networked constellations. They enable security at rest, secure content caching, and deeper inspection at gateways otherwise obscured by tunneling
