On models of algebraic group actions

Proceedings - Mathematical Sciences, 2022
We show that every action of a smooth algebraic group on a variety admits a normal projective model. Along the way, we present new proofs of some basic results on algebraic transformation groups, including Weil’s regularization theorem.

Blind Schnorr Signatures and Signed ElGamal Encryption in the Algebraic Group Model

International Conference on the Theory and Application of Cryptographic Techniques, 2020
The Schnorr blind signing protocol allows blind issuing of Schnorr signatures, one of the most widely used signatures. Despite its practical relevance, its security analysis is unsatisfactory.
