Paper: Decentralized Multi-Authority Attribute-Based Inner-Product …
WebWe present the first unbounded non-zero predicate IPFE (UNP-IPFE) that successfully recovers x, y if w, v ≠ 0. We generically transform an unbounded quadratic FE (UQFE) scheme to weak attribute-hiding UNP-IPFE in both public and secret key settings. Interestingly, our secret key simulation secure UNP-IPFE has succinct secret keys and is ... Web5 Jun 2024 · In 2015, Abdalla et al. introduced Inner-Product Functional Encryption, where both ciphertexts and decryption keys are vectors of fixed size n, and keys enable the computation of an inner product between the two. In 2015, Abdalla et al. introduced Inner-Product Functional Encryption, where both ciphertexts and decryption keys are vectors of … Web3 Sep 2016 · This work extends the reach of functional encryption schemes that are provably secure under simple assumptions against unbounded collusion to include function-hiding inner product schemes and relies only on the SXDH assumption to satisfy a natural indistinguishability-based security notion.
