An Approach to Secure Data in Disruption Tolerant Network
Mobile nodes in secured environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technologies are becoming successful solutions that allow wireless devices carried by individuals to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. The concept of attributebased encryption (ABE) is a promising approach that fulfils the requirements for secure data retrieval in DTNs. Cipher text-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the access control issues. Data can be easily hacked by third person if they have the key credentials with them. To overcome the drawback of existing system we planned to proposed a system where data will be transferred securely in DTN from one end to other end with respect to parameters like geo-location, valid timestamp and ip-address.
