Abstract EN
Decentralized attribute-based encryption (ABE) is a special form of multiauthority ABE systems, in which no central authority and global coordination are required other than creating the common reference parameters.
In this paper, we propose a new decentralized ABE in prime-order groups by using extended dual system groups.
We formulate some assumptions used to prove the security of our scheme.
Our proposed scheme is fully secure under the standard k-Lin assumption in random oracle model and can support any monotone access structures.
Compared with existing fully secure decentralized ABE systems, our construction has shorter ciphertexts and secret keys.
Moreover, fast decryption is achieved in our system, in which ciphertexts can be decrypted with a constant number of pairings.
