A multi-authority approach to various predicate encryption types [PDF]
Designs, Codes and Cryptography, 2019 Abstract We propose a generic construction for fully secure decentralized multiauthority predicate encryption. In such multiauthority predicate encryption scheme, ciphertexts are associated with one or more predicates from various authorities and only if a user has a set of decryption keys that evaluates all predicates to true, the user is able to ...

The Dilemma Between Fiscal Decentralization and Budget Balance
Transylvanian Review of Administrative Sciences, 2022 This paper explores the effects of the distribution of fiscal authority for fiscal decentralization on the U.S. state budget balance. Numerous scholars have pointed out that fiscal institutions play an important role in achieving budget balance, but ...

Multi-authority Attribute-based Encryption Scheme with Policy Hiding [PDF]
Jisuanji gongcheng, 2018 Most existing attribute-based encryption schemes of hidden policies are directed to a single authority,without taking into account the situation where the users’ attributes are managed by multi-authority,having the problems such as low-efficient of key ...

Multi-authority ABS supporting dendritic access structure
Tongxin xuebao, 2017 Attribute-based signature (ABS),which could realize fine-grained access control,was considered to be an important method for anonymous authentication in cloud computing.However,normal ABS only provided simple access control through threshold structure ...
