“…For attribute revocation, the related AAs need to communicate with nonrevoked users, who hold the key with the revoked attribute and also the CSP for update the ciphertext. The communication cost of the scheme [37] is less than our scheme and the scheme [12]. Our scheme and the scheme [12] have almost the same communication overhead when the key is updated, but when updating the ciphertext, our scheme is encouraging over the scheme [12] .…”

Some schemes used the updated version number to generate the updated key by the attribute authority to revoke attributes [35][36][37]. In the scheme [38][39][40], the cloud is used to perform the revocation process.…”
