Abstract: Highlights•Our scheme is based on the learning with errors (LWE) problem, which is believed to be quantum-resistant.•Our scheme supports polynomial-depth policy function and has short secret keys.•Our scheme satisfies selective revocation list security in the standard model under the LWE assumption.•We design an efficient revocable (key-policy or ciphertext-policy) ABE scheme for any arithmetic circuit.
