We provide constructions of (m, 1)-programmable hash functions (PHFs) for m ≥ 2. Mimicking certain programmability properties of random oracles, PHFs can, e.g., be plugged into ...
Releasing a classical digital signature faces to privacy issues. Indeed, there are cases where the prover needs to authenticate some data without making it possible for any malicio...
A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...
Analysis of IC technology trends indicates that Iddq testing may be approaching its limits of applicability. The new concept of the current signature may expand this limit under t...
