A Secured Message Exchange Scheme in Post-Disaster Environment Using Delay Tolerant Network
Journal Title:GLOBAL JOURNAL FOR RESEARCH ANALYSIS
Major Disasters turmoil human activity and disconnect communication services such as phones and Internet for weeks.
To cope with such situations smart phone-based ad-hoc opportunistic network can be built to take rapid actions. Relief
workers and victims can use these devices not only to produce information that can be incorporated into a shared
situation awareness application, but also to validate the authenticity of information they use. In such sensational environment secure and
immediate communication (or message exchange) among small groups and to remote monitoring system is quite important as there can be
some malicious node intend to intercept and alter those sensitive data for the purpose of corruption. To implement secured message exchange,
shared group keys can be assigned for encryption-decryption purposes to assure security. In this paper we can ensure secure communication
among different components (called nodes) in Delay/Disaster Tolerant Network (DTN).The performance of the proposed scheme is evaluated
using ONE simulator .
