Improved (Hierarchical) Inner-Product Encryption from Lattices
predicate encryption (hierarchical) inner-product encryption lattices
2016/1/3
Inner-product encryption (IPE) provides fine-grained access control and has attractive applications. Agrawal, Freeman, and Vaikuntanathan~(Asiacrypt 2011) proposed the first IPE scheme from lattices b...
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...
The Relation and Transformation between Hierarchical Inner Product Encryption and Spatial Encryption
public-key cryptography / Functional Encryption Hierarchical Inner Product Encryption Spatial Encryption Generic Construction
2012/3/26
Hierarchical inner product encryption (HIPE) and spatial encryption (SE) are two important classes of functional encryption (FE) that have a large number of applications. Although HIPE and SE both inv...
Fully Secure Functional Encryption：Attribute-Based Encryption and (Hierarchical) Inner Product Encryption
Secure Functional Encryption Attribute-Based Encryption Inner Product Encryption
2010/3/16
In this paper, we present two fully secure functional encryption schemes. Our rst result
is a fully secure attribute-based encryption (ABE) scheme. Previous constructions of ABE
were only proven to...
