PAC-FIT: An efficient privacy preserving access control scheme for fog-enabled IoT
Abstract
PAC-FIT addresses the following aspects of CP-ABE simultaneously: attribute revocation, attribute addition, outsourcing, key-escrow resistance, for cloud-fog-IoT architecture. Unlike the existing CP-ABE schemes, the user holds a constant size secret key which remains unchanged during any update. The security analysis proves that PAC-FIT is secure against Chosen-Plaintext Attack under Decisional Bilinear Diffie-Hellman assumption.
