Multi-authority attribute-based encryption with efficient user revocation in cloud computing
网络与信息安全学报, 2016 An efficient user revocable multi-authority ABE scheme was proposed,a “hybrid decryption key” for each user isused to achieve efficient user revocation.Comparing with the existing schemes,this scheme is more effective in user revocation.In addition,the ...

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 Secret-Ballot Elections with Linear Work [PDF]
, 1996 We present new cryptographic protocols for multi-authority secret ballot elections that guarantee privacy, robustness, and univer- sal verifiability. Application of some novel techniques, in particular the construction of witness hiding/indistinguishable protocols from Cramer, Damgård and Schoenmakers, and the verifiable secret sharing scheme of ...

Multi-authority Attribute Based Encryption [PDF]
, 2007 In an identity based encryption scheme, each user is identified by a unique identity string. An attribute based encryption scheme (ABE), in contrast, is a scheme in which each user is identified by a set of attributes, and some function of those attributes is used to determine decryption ability for each ciphertext. Sahai and Waters introduced a single
