Abstract

"MéTODO CRIPTOGRáFICO PARA PROTEGER UM CHIP ELETRôNICO CONTRA FRAUDE". A presente invenção refere-se a um método criptográfico para proteger um chip eletrônico contra fraude e um dispositivo incluindo uma chip eletrônico que é adaptado para proteger o chip eletrônico contra fraude. O método inclui: - combinar (1) alguns ou todos os parâmetros de entrada (E~ m~) para fornecer um item de dados de saída E<39>= (e<39>~ 1~,, e<39>~ 2~, .... e<39>~ n~, .... e<39>~ N~) .; - alterar (2) o estado de um autómato de estado finito de um estado antigo para um novo estado em função do item de dados E<39> = (e<39>~ 1~, e<39>~ 2~, ..., e<39>~ n~, .... e<39>~ N~)., e - calcular (3) um certificado (S) por intermédio de uma função de saída tendo pelo menos um estado como um argumento de entrada. O dispositivo inclui: - dispositivos de associação - um autómato de estado finito; e - dispositivos de saída para calcular um certificado.
