Survey Paper on Attribute Based Encryption in Disruption Tolerant Network

2016 International Journal of Science and Research (IJSR)  
Mobile nodes connecting one node to another node faces some networking connectivity problem in common environment. In military network i.e in battle field are not supposed to suffer network connectivity problem. Disruption tolerant network (DTN) technologies are the solution for this problem. Attribute based encryption (ABE) gives the secure way for data delivery in Disruption Tolerant Network. The most promising cryptographic solution is introduced to control the access issues called Cipher

The Cipher text-policy Attribute Based Encryption for secure data retrieval in decentralized Disruption Tolerant Networks (DTNs) where multiple key authorities manage their attributes independently. It gives an 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. But concept of applying CP-ABE in DTNs introduces security and privacy problems with regard to Attribute revocation, Key escrow, Coordination of attributes issued from different authorities.
