Abstract


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 [8].
