Marco Cianfriglia, Elia Onofri, Marco Pedicini

We address the problem of user fast revocation in the lattice based CP-ABE by extending the scheme originally introduced in [A ciphertext policy attribute-based encryption scheme without pairings. J. Zhang, Z. Zhang - ICISC 2011]. While a lot of work exists on the construction of revocable schemes for CP-ABE based on pairings, works based on lattices are not so common, and – to the best …
