Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine- grained access control on encrypted data. In its key-policy flavor ...

All current attribute-based encryption schemes that admit reasonably expressive decryption policies produce ciphertexts whose size depends at least linearly on ...

In this paper, we present an attribute-based encryption scheme with constant-size cipher texts from zero inner product. The encrypter can select the ...

This paper presented the first results for expressive KP-ABE schemes with constant-size ciphertexts. In the future, it will be interesting to see if shorter.

In this paper we propose the first scheme whose ciphertexts have constant size. Our scheme works for the threshold case.
