Homomorphic Signatures for Polynomial Functions
Polynomial Functions Homomorphic Signatures
2015/8/5
We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an efficient algorithm t...
Linearly homomorphic signatures over binary fields and new tools for lattice-based signatures
binary fields lattice-based signatures
2015/8/5
Our scheme can be used to authenticate linear transformations of signed data, such as those arising when computing mean and least squares fit or in networks that use network coding. Our construction g...
