Attribute-based encryption (ABE) can support a fine-grained access control to encrypted data. When the user's secret-key is compromised, the ABE system has to revoke its decryption privileges to prevent the leakage of encrypted data. Although there are many constructions about revocable ABE from bilinear maps, the situation with lattice-based constructions is less satisfactory, and a few efforts were made to close this gap. In this work, we propose the first lattice-based server-aided revocabledoi:10.1155/2020/1460531 fatcat:6kevau6x5baivlri5wt2fyjtnu
