log-aesthetic curve and filterdigital filterdiscrete curve and surfaceThe aesthetic curves include the logarithmic (equiangular) spiral, clothoid, and involute curves. Although most of them are expressed only by an integral form of the tangent vector, it is possible to interactively generate and ...

We provide evidence that the unforgeability of several discrete-log based signatures like Schnorr signatures cannot be equivalent to the discrete log problem in the standard model. This contradicts in nature well-known proofs standing in weakened proof m
Discrete Log RepresentationBilinear PairingMultilinearIdentification protocols are powerful tools in many areas of cryptography. A prover's identity (ID) has n distinct secrets which in total construct her identity. When a prover, Peggy, wants to prove to a verifier, Victor, that she is the ...

Distributed key generation is a main component of threshold cryptosystems and distributed cryptographic computing in general. Solutions to the distributed generation of private keys for discrete-log based cryptosystems have been known for several years and used in a variety of protocols and in many rese...
