Adaptively Attribute-Hiding - Hierarchical Inner Product

Explore a 22-minute conference talk from Eurocrypt 2012 by authors Tatsuaki Okamoto and Katsuyuki Takashima on Adaptively Attribute-Hiding (Hierarchical) Inner Product Encryption. Delve into functional encryption, focusing on adaptive secure and fully attribute-hiding inner product encryption. Examine the challenger's role, previous works in the field, and key techniques such as the Dual Pairing Vector Space approach. Learn about intractable problems on DPVS and the proposed basic fully attribute-hiding IPE scheme. Understand the Dual System Encryption methodology and its application. Discover key ideas for short public and secret key IPE, and explore adaptively fully-AH IPE with constant-size secret keys.
