In the transformation of data sources in military systems, the security constraints have serious issues. In order to retrieve the data secured and efficiently they use the CP-ABE. Cipher-text Policy Attribute-Based Encryption (CP-ABE) is a promising cryptographic solution to the access control issues. In this paper, they propose a secure data retrieval scheme using CP-ABE for decentralized where multiple key authorities manage their attributes independently. The problems of key escrow, revocation and co-ordination are discussed and they demonstrate how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network.
