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 ...

IEEE Access, 2018 Nowadays, secure data access control has become one of the major concerns in a cloud storage system. As a logical combination of attribute-based encryption and attribute-based signature, attribute-based signcryption (ABSC) can provide confidentiality and

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 ...

Privacy preserving cloud data access with multi-authorities [PDF]
2013 Proceedings IEEE INFOCOM, 2013 Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand and low-cost usage of computing resources. Those advantages, ironically, are the causes of security and privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control.

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

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 ...

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 ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing
