Abstract

UN METODO Y APARATO PARA LA IDENTIFICACION DE UN PROBADOR, PARA UNA VERIFICACION EN LA QUE EL PROBADOR DEMUESTRA SU CONOCIMIENTO DE UNA PERMUTACION SECRETA N, TAL QUE VN = K(A) PARA A Y V PUBLICAMENTE CONOCIDOS, DONDE TODAS LAS OPERACIONES ARITMETICAS SON REALIZADAS A MODULO P. LA PRUEBA ACTUAL NO REVELA ALGUN CONOCIMIENTO DE N, Y ASI NO PUEDE SER EMPLEADO POR VERIFICADORES DESHONESTOS O INDISCRETOS PARA MAS TARDE REPRESENTARLES PARA EL PROBADOR. EL NUEVO ESQUEMA ES MUCHO MAS RAPIDO QUE LOS ESQUEMAS DE IDENTIFICACION RSA Y FIAT-SHAMIR.
