Secure descriptive message dissemination in DTNs

Abstract

Mobile nodes in some challenging network scenarios suffer from intermittent connectivity and frequent partitions e.g. battlefield and disaster recovery scenarios. Disruption Tolerant Network (DTN) technologies are designed to enable nodes in such environments to communicate with one another. A key feature of DTN technology is the late-binding capability that allows messages destined to a descriptive name to be resolved progressively until the messages are delivered to one or several recipients. In this paper, we describe a flexible security solution that allows messages destined to descriptive names to be sent securely such that unauthorized personnel is not allowed to eavesdrop on them. Our solution builds on the attributed based cryptography system. In addition, we describe our implementation of a late-binding router that supports our security solution. We also present our prototyping experience.

A Secure Data Exchange System in Wireless Delay Tolerant Network Using Attribute-Based Encryption

“…In the similar way to the previous works [19], [20], the exchanged content data are encrypted using the CP-ABE, and the ciphertext is sent from the source node to the destination node in the storeand-forward way of the DTN. Due to the hybrid approach, the temporal key is encrypted by CP-ABE, and the content data is encrypted by AES on the key.…”

“…The networks include Wireless Sensor Networks (WSNs) [7], Mobile Ad-hoc NETworks (MANETs) [20], Vehicle Ad-hoc NETworks (VANETs) [9], etc. In such networks, mobile devices construct their own autonomous network topology to communicate with each other, by exchanging routing messages to update their routing tables.…”

“…In the access control, the flexibility and granularity of the access control is required, which depends on the adopted cryptosystem. The previous works [19], [20] employed Attribute-Based Encryption (ABE) [15] for encrypting the content data exchanged in DTNs. The access is controlled using the attribute possession of the nodes, where a secret key corresponding to each own attribute is issued securely during the initial registration phase.…”

“…Meanwhile, Ref. [20] described a flexc 2017 Information Processing Society of Japan ible security solution in DTNs to let messages destined to representative names to be sent securely such that adversaries are not able to eavesdrop the messages easily. The solution implemented a prototype system using JAVA based RAPID router [17].…”

Secure Content Centric Mobile Network

“…lawn mower belongs to both "lawn care" and "appliances" categories, will be encrypted such that any user who is interested in either "appliances" or "lawn care" will be able to retrieve such data items from the storage nodes. Details of our enhanced CP-ABE design which includes new features such as supporting dynamic attributes, negative attributes and user revocation can be found in [26]. The dynamic attributes will be useful for region-based content distribution e.g.…”
