Improved Inner-product Encryption with Adaptive Security and Full Attribute-hiding
public-key cryptography Full Attribute-hiding
2018/11/16
In this work, we propose two IPE schemes achieving both adaptive security and full attribute-hiding in the prime-order bilinear group, which improve upon the unique existing result satisfying both fea...
Adaptively Simulation-Secure Attribute-Hiding Predicate Encryption
predicate encryption partially-hiding simulation-based adaptive security
2018/11/13
This paper demonstrates how to achieve simulation-based strong attribute hiding against adaptive adversaries for predicate encryption (PE) schemes supporting expressive predicate families under standa...
Predicate- and Attribute-Hiding Inner Product Encryption in a Public Key Setting
inner product encryption predicate-hiding
2014/3/6
In this paper, we propose a reasonable definition of predicate-hiding inner product encryption (IPE) in a public key setting, which we call inner product encryption with ciphertext conversion (IPE-CC)...
Adaptively Attribute-Hiding (Hierarchical) Inner Product Encryption
public-key cryptography / Functional Encryption Predicate Encryption Attribute-Hiding
2012/3/23
This paper proposes the first inner product encryption (IPE) scheme that is adaptively secure and fully attribute-hiding (attribute-hiding in the sense of the definition by Katz, Sahai and Waters), wh...
