There are partitions in military environments such as a battlefield or a hostile region.They are likely to suffer from intermittent network connectivity.They having frequent partitions. Disruption-tolerant network DTN technologies are is a true and easy solutions.DTN is a Disruption-tolerant network.It allow devices which are wireless and carried by peoples in a military to interact with each other.These devices access the confidential information or command reliably by exploiting external storage nodes. In these networking environments DTN is very successful technology. When there is no wired connection between a source and a destination device, the information from the source node may need to wait in the intermediate nodes for a large amount of time until the connection would be correctly established.one of the challenching approach is a ABE.that is attribute-based encryption which fulfills the requirements for secure data retrieval in DTNs. The another concept is Cipher text Policy ABE (CP-ABE).it gives a appropriate way of encryption of data. the encryption includes the attribute set that the decryption needs to possess in order to decrypt the cipher text.hence, Many users can be allowed to decrypt different parts of data according to the security policy

Attribute Based Secure Military Data Retrieval System for Decentralized Disruption Tolerant Networks

In this section, we provide a multi authority CP-ABE scheme for secure data retrieval in decentralized DTNs. Each local authority issues partial personalized and attribute key components to a user by performing secure 2PC protocol with the central authority. Each attribute key of a user can be updated individually and immediately. Thus, the scalability and security can be enhanced in the proposed scheme. Since the first CP-ABE scheme proposed by Bettencourt et al , dozens of CP-ABE schemes have been proposed. The subsequent CP-ABE schemes are mostly motivated by more rigorous security proof in the standard model. However, most of the schemes failed to achieve the expressiveness of the Bettencourt et al.’s scheme, which described an efficient system that was expressive in that it allowed an encrypt or to express an access predicate in terms of any monotonic formula over attributes. Therefore, in this section, we develop a variation of the CP-ABE algorithm partially based on (but not limited to) Bettencourt et al.’s construction in order to enhance the expressiveness of the access control policy instead of building a new CP-ABE scheme from scratc

CP-ABE IN DECENTRALIZED DISRUPTION-TOLERANT MILITARY NETWORKS FOR SECURE RETRIEVAL OF DATA

In this rapidly growing world, communication involves transfer of confidential information across the globe within a short amount of time. This kind of technical communication involves network of communicating devices. These devices will be carrying the confidential data across the devices which may be far apart. In military environment, communication disruption can occur because of intermittent network connectivity. Solution found for these kinds of disruption is the Disruption Tolerant Network (DTN) technology. This technology allows the soldiers to reliably access the data by using the capacity of the external storage nodes. Most challenging issue found in this DTN technology is enforcement of authorization policies and update of policies for the retrieval of confidential data.  CP-ABE is one such cryptographic method which provides the solution to the access control issues. But there exists several problems with regard to key escrow, attribute revocation and coordination of attributes which are issued by different key authorities when applying CP-ABE in decentralized DTNs. In this paper, more secured method for the retrieval of confidential data using CP-ABE for decentralized DTNs is proposed where sets of attributes will be generated and managed by multiple authorities independently and addresses several existing proble

A Cluster Tree Based Model for Secure Data Retrieval in Military using Wireless Sensor Networks

Wireless sensor networks (WSNs) can be used in military environments such as a battlefield tracking the enemies. One of the challenging issues in this scenario is enforcement of authorization policies and the policies update for secure data retrieval. CP-ABE is using efficient and secure data retrieval method for decentralized DTNs. However implementing Cipher text-Policy Attribute – Based Encryption (CP-ABE) in decentralized DTNs where the key authorities might be compromised or not fully trusted. In this paper we propose a secured data retrieval method using Cluster Tree Based Model proposes grouping the slave nodes, where each node has an individual group head. The cluster model provide key to group head and the group head will distribute the key to all members and implementing Position-based Aggregator Node Election protocol (PANEL) is a position-based clustering routing protocol for WSNs. The main goal of PANEL is to elect aggregators, i.e., CHs. PANEL protocol are used to balance the network node load pressure and reduces the communication load

Comparitive Study on Secure Data Retrieval Framework for Military Networks

In the immensely colossal number of outgrowing commercial environment each and everything depends on the other sources to transmit the data securely and maintain the data as well in the conventional medium. Portable nodes in military environments, for example, a front line or an antagonistic area are prone to experience the undergo of eccentric system network and frequent partitions.
