Abstract

Abstract: One of the most preferred encryption techniques for data sharing in cloud environment is Ciphertext-Policy Attribute Based Encryption (CP-ABE). An efficient File Hierarchy CP-ABE (FH-CP-ABE) scheme using an integrated access structure was proposed by Wang and colleagues. Their working construction was based on symmetric pairing. In this article, we propose an efficient Asymmetric File Hierarchy Ciphertext-Policy Attribute Based Encryption (AFH-CP-ABE) which is based on an asymmetric pairing construction using denominator elimination and twist mapping. We apply this optimized Tate pairing in the proposed AFH-CP-ABE to find out its computational costs for encryption and decryption using gmp 6.0.0 library and then compared with existing schemes.
