  A Quantum Ciphertext-Policy Attribute-Based Encryption scheme (QCP-ABE) has
been presented. In classical domain, most of the popular ABE schemes are based
on the hardness of the Bilinear Diffie-Hellman Exponent problem, which has been
proven to be vulnerable against Shor's algorithm. Recently, some quantum safe
ABE schemes have been proposed exploiting the Lattice problem. However, no
efficient Quantum Attribute-Based Encryption scheme has been reported till
date. In this backdrop, in the present initiative, we propose a quantum CP-ABE
scheme exploiting Quantum Key Distribution (QKD) and Quantum Error Correcting
code. A Semi Quantum version of the scheme has also been considered. Finally,
we introduced dynamic access structure in our proposed protocols.
