CP-ABE Secure Data Retrieval
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
Partitions in military environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity. Disruption-tolerant network DTN technologies are true and easy solutions. DTN is a Disruption-tolerant network. Thus a new methodology is introduced to provide successful communication between each other as well as access the confidential information provided by some major authorities like commander or other superiors. This system provides efficient scenario for authorization policies and the policies update for secure data retrieval in most challenging cases. The most promising cryptographic solution is introduced to control the access issues called Cipher text Policy Attribute Based Encryption (CP-ABE). The Attribute-based encryption scheme fulfills the requirements for secure data retrieval in DTNs. The concept is Cipher text Policy ABE), it gives an appropriate way of encryption of data. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data retrieval. 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.
