Security and Routing in a Disconnected Delay Tolerant Network

Providing internet access in disaster-affected areas where there is little to no internet connectivity is extremely difficult. This paper proposes an architecture that utilizes existing hardware and mobile applications to enable users to access the Internet while maintaining a high level of security. The system comprises a client application, a transport application, and a server running on the cloud. The client combines data from all supported applications into a single bundle, which is encrypted using an end-to-end encryption technique and sent to the transport. The transport physically moves the bundles to a connected area and forwards them to the server. The server decrypts the bundles and forwards them to the respective application servers. The result is then returned to the original client application via the network of transports used previously. This solution provides a convenient way to establish connectivity in disconnected areas without additional hardware and can accommodate various application data. Furthermore, it ensures data integrity, confidentiality, and authentication by encrypting and validating the data during transmission.
