Interoperability, Trust Based Information Sharing Protocol and Security: Digital Government Key Issues
Improved interoperability between public and private organizations is of key
significance to make digital government newest triumphant. Digital Government
interoperability, information sharing protocol and security are measured the
key issue for achieving a refined stage of digital government. Flawless
interoperability is essential to share the information between diverse and
merely dispersed organisations in several network environments by using
computer based tools. Digital government must ensure security for its
information systems, including computers and networks for providing better
service to the citizens. Governments around the world are increasingly
revolving to information sharing and integration for solving problems in
programs and policy areas. Evils of global worry such as syndrome discovery and
manage, terror campaign, immigration and border control, prohibited drug
trafficking, and more demand information sharing, harmonization and cooperation
amid government agencies within a country and across national borders. A number
of daunting challenges survive to the progress of an efficient information
sharing protocol. A secure and trusted information-sharing protocol is required
to enable users to interact and share information easily and perfectly across
many diverse networks and databases globally.Comment: 20 page
A Lightweight and Attack Resistant Authenticated Routing Protocol for Mobile Adhoc Networks
In mobile ad hoc networks, by attacking the corresponding routing protocol,
an attacker can easily disturb the operations of the network. For ad hoc
networks, till now many secured routing protocols have been proposed which
contains some disadvantages. Therefore security in ad hoc networks is a
controversial area till now. In this paper, we proposed a Lightweight and
Attack Resistant Authenticated Routing Protocol (LARARP) for mobile ad hoc
networks. For the route discovery attacks in MANET routing protocols, our
protocol gives an effective security. It supports the node to drop the invalid
packets earlier by detecting the malicious nodes quickly by verifying the
digital signatures of all the intermediate nodes. It punishes the misbehaving
nodes by decrementing a credit counter and rewards the well behaving nodes by
incrementing the credit counter. Thus it prevents uncompromised nodes from
attacking the routes with malicious or compromised nodes. It is also used to
prevent the denial-of-service (DoS) attacks. The efficiency and effectiveness
of LARARP are verified through the detailed simulation studies.Comment: 14 Pages, IJWM
