Outsourced ciphertext-policy attribute-based encryption with partial policy hidden

International Journal of Distributed Sensor Networks, 2020
Attribute-based encryption is an efficient and flexible fine-grained access control scheme. However, how to realize the attribute privacy concerns in the access policy and optimize the heavy computing overhead have been not adequately addressed.

Uncovering Edtech's Embedded Values: Making the Case for Socio‐Technical Audits in Ethnographic Inquiry

Anthropology &Education Quarterly, Volume 57, Issue 3, September 2026.
ABSTRACT Drawing on three ethnographic studies of secondary schools in England, this article makes a case for “socio‐technical audits”—a method combining technological walkthroughs with observations, workshops, and interviews—as part of ethnographic inquiry. A case example is presented to illustrate how the integration of socio‐technical audits enables

Accountable CP-ABE with Public Verifiability: How to Effectively Protect the Outsourced Data in Cloud

, 2017
Ciphertext-policy attribute-based encryption, denoted by CP-ABE, extends identity based encryption by taking a set of attributes as users’ public key which enables scalable access control over outsourced data in cloud storage services.

CP-ABE scheme supporting partially hidden access policy

Tongxin xuebao
Most of the existing ciphertext-policy attribute-based encryption (CP-ABE) schemes that support outsourced decryption do not consider the privacy protection of the ciphertext access policy, while some schemes that support policy hidden have the problem ...

Decryption phase in Norwegian electronic voting [PDF]

, 2016
We describe an efficient and secure decryption protocol to the Norwegian Internet voting project. We first adapt Groth’s shuffle-decryption from 2010 to our purpose, and we prove all security properties in the random oracle model.

Generic Construction of Outsourced Attribute-Based Encryption Without Key Escrow

IEEE Access, 2018
Attribute-based encryption (ABE) has a broad developing prospect in fine-grained sharing of ciphertext in the background of cloud computing. However, most of ABE schemes have a potential security risk called key escrow problem because users’ ...
