Key Escrow Removal Using Random Oracle in CP-ABE for Security in Military Networks

Abstract

Abstract:In this paper, Confidential Data Security Methodology has been modified by using random key authority generation replacing two-party computation protocol to remove the disadvantage KEY ESCROW, with recent adoption and spreading of data sharing. One or more trusted parties supply information to decrypt ciphertext. Trusted parties are known as central authorities provide information in form of data recovery keys. Key escrow refers to the safeguarding of those data recovery keys. In this paper random key distribution in CP-ABE is explained and simulated to secure the confidential data. The definitive approach CP-ABE provides the addition of access policies and its updates. It has been demonstrated how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network.
