摘要：Mobile nodes in military environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant networks (DTN) technologies are emerging to become most successful solutions which allows the wireless devices to be carried by the soldier in-order to make communication with each other and access the information that are confidential or commands are made reliable by exploiting the external storage nodes. There are some of the most challenging issues present in this scenario, they are enforcement of authorization policy and policies that are updated for processing the data retrieval in a secure manner. Cipher text policy attribute-based encryption (CPABE) is a significant solution for cryptography in-order to access the control issues. The problem of implementing the CP-ABE is a de-centralized DTNs origins many security and privacy challenges regarding to attribute revocation key escrow, and co-ordinates of attributes given from different authorities. In this paper, we propose a secure scheme for retrieval of data using CP-ABE for de-centralized DTNs where the authorities of multiple key look after their attribute independently. We illustrate how to apply the proposed system to manage the confidential data with security and efficiency, distributed in the Disruption-tolerant military networks
