In order to study the resistance of a block cipher against boomerang attacks, a tool called the Boomerang Connectivity Table (BCT) for S-boxes was recently introduced. Very little is known today about...
Black-Box Constructions of Signature Schemes in the Bounded Leakage Setting
identity-based signature certificateless signature black-box construction
2017/6/28
To simplify the certificate management procedures, Shamir introduced the concept of identity-based cryptography (IBC). However, the key escrow problem is inherent in IBC. To get rid of it, Al-Riyami a...
Non-Malleable Zero Knowledge: Black-Box Constructions and Definitional Relationships
foundations / Non-malleability zero knowledge commitments black-box constructions
2012/3/26
This paper deals with efficient non-malleable zero-knowledge proofs for NP, based on general assumptions. We construct a simulation-sound zero-knowledge protocol for NP, based only on the black-box us...
(Nearly) optimal black-box constructions of commitments secure against selective opening attacks
commitments black-box lower bounds zero knowledge
2009/11/18
Selective opening attacks against commitment schemes occur when the commitment
scheme is repeated in parallel (or concurrently) and an adversary can choose depending on
the commit-phase transcript t...
