Hidden Field Equations

Hidden Field Equations

Hidden Fields Equations, commonly abbreviated to HFE, is a public key cryptosystem. HFE uses polynomial operations over finite fields. It was proposed by Jacques Patarin at Eurocrypt 96 following the ideas of Matsumoto and Imai. It has long been regarded as the most promising cryptosystem of the kind.fact|date=June 2007 Some advanced attacks were discovered on HFE, none of them has been devastating, however.fact|date=June 2007 HFE is very fast in encryption and produces short digital signatures. It is much less studied than the RSA. HFE has been patented by Jacques Patarin. The patent expires on July 24 2016.
