Abstract
In this paper, we propose new non-monotonic attribute-based encryption schemes with compact parameters.
The first three schemes are key-policy attribute-based encryption (KP-ABE) and the fourth scheme is ciphertext-policy attribute-based encryption (CP-ABE) scheme.
\begin{itemize}
\item Our first scheme has very compact ciphertexts. The ciphertext overhead only consists of two group elements and this is the shortest in the literature.
Compared to the scheme by Attrapadung et al. (PKC2011), which is the best scheme in terms of the ciphertext overhead, our scheme shortens ciphertext overhead by
