Abstract
Un nuevo esquema criptografía asimétrica que puede ser utilizado en cifrado, firma y autenticación. El esquema está basado sobre ecuacionespolinomiales públicas de pequeno grado con valor en un anillo finito K. El mecanismo no es necesariamente biyectivo. La clave secreta permite ocultarecuaciones polinomiales con valor de extensiones del anillo K. La resolución de estas ecuaciones permite, si se dispone de la clave secreta, efectuaroperaciones que no son factibles únicamente a partir de la clave pública.
