Abstract
METODO PARA IDENTIFICAR UNA ENTIDAD QUE INCLUYE LOS PASOS PARA ESTABLECER UNA CLAVE PUBLICA PARA DICHA ENTIDAD CONSISTENTE EN UN MODULO N QUE ES EL PRODUCTO DE AL MENOS DOS NUMEROS PRIMOS, Y UNA SECUENCIA DE K NUMEROS (V1,...,VK). PARA ELLO SE COMPUTA UNA CLAVE PRIVADA DE LA ENTIDAD FORMADA POR K NUMEROS (S1,...,SK) QUE SATISFACEN LA IGUALDAD (SJ)^D*VJ=1 (MOD N) PARA TODO J COMPRENDIDO ENTRE 1 Y K, EN DONDE EL EXPONENTE D ES UNA CONSTANTE UNIVERSALMENTE CONOCIDA, MAYOR QUE 1; SE TRANSMITE DESDE LA ENTIDAD A UN VERIFICADOR X=R*D (MOD N) EN DONDE R ES UN NUMERO ALEATORIO COMPRENDIDO ENTRE 0 Y N; SE TRANSMITE DESDE EL VERIFICADOR HASTA LA ENTIDAD UNA SECUENCIA DE K NUMEROS ALEATORIOS (E1,...,EK) COMPRENDIDOS TODOS ELLOS ENTRE 0 Y D; SE TRANSMITE AL VERIFICADOR EL VALOR Y EXPRESADO EN LA FORMULA (32) DE LA FIGURA Y SE VERIFICA LA IGUALDAD DE LA ENTIDAD COMPROBANDO LA IGUALDAD (46) DE LA FIGURA.
