The Fiat-Shamir Transform for Group and Ring Signature Schemes
The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...

Grouping Levels of Exposure with Same Observable Effects before Class Prediction in Toxicogenomics
—Gene expression profiling in toxicogenomics is often used to find molecular signature of toxicants. The range of doses chosen in toxicogenomics studies does not always represe...

Chameleon Hashing Without Key Exposure
Abstract. Chameleon signatures are based on well established hashand-sign paradigm, where a chameleon hash function is used to compute the cryptographic message digest. Chameleon s...

Signature Schemes and Anonymous Credentials from Bilinear Maps
Abstract. We propose a new and efficient signature scheme that is provably secure in the plain model. The security of our scheme is based on a discrete-logarithm-based assumption p...

An improvement of nonrepudiable threshold proxy signature scheme with known signers
In a (t, n) threshold proxy signature scheme, which is a variant of the proxy signature scheme, the proxy signature key is shared among a group of n proxy signers delegated by the ...
