Hidden Polynomial Cryptosystems
Abstract: We propose public-key cryptosystems with public key a
system of polynomial equations, algebraic or differential, and
private key a single polynomial or a small-size ideal. We set up
probabilistic encryption, signature, and signcryption
Category / Keywords: Public key, hidden monomial, HFE, differential algebra, TTM, probabilistic encryption, signcryption, private key.
