Abstract

La presente se refiere a un procedimiento criptográfico asimétrico contra el fraude de una plaqueta electronica, en transacciones entre una aplicacion y la plaqueta electronica, que consiste en calcular en la plaqueta electronica un valor V de autentificacion a partir de parámetros de entrada. El procedimiento comprende las etapas que consisten en: producir (1) por medio de la plaqueta un numero seudo-aleatorio denominado clave aleatoria r propia de la transaccion por medio de un generador seudo-aleatorio serie incluido en la plaqueta; transmitir (2) de la plaqueta a la aplicacion un parámetro x calculado por la aplicacion previamente a la transaccion, relacionado con la clave aleatoria r a través de una relacion matemática y almacenado en memoria de datos de la plaqueta; calcular (3) por la plaqueta un parámetro y por medio de una funcion serie que tiene como parámetros de entrada al menos la clave aleatoria r propia de la transaccion y una clave s privada que pertenece a un par de claves asimétricas (s, p), constituyendo este parámetro y todo o parte del valor de autentificacion V; transmitir (4) el valor de autentificacion V de la plaqueta a la aplicacion, y verificar (5) por la aplicacion el citado valor de autentificacion V por medio de la funcion de verificacion cuyos parámetros de entrada consisten exclusivamente en parámetros publicos, que contienen al menos la clave p publica.
