Abstract

"PROCESSO DE TROCA SEGURA DE MENSAGENS DE INFORMAçãO". A invenção refere-se a um processo de troca segura de mensagens de informação enviadas sucessivamente de uma plataforma emissora para uma plataforma receptora, caracterizado pelo fato de: a) uma seq³ência de inicialização na qual pelo menos uma mensagem de inicialização M~ 0~ contendo a informação da data t~ 1~ de envio da primeira mensagem de informação M~ 1~ é trocada entre a plataforma emissora e a plataforma receptora; b) uma seq³ência de transmissão das mensagens de informação, na qual: - as mensagens de informação são enviadas sucessivamente pela plataforma emissora com intervalos de tempo <30>T~ E~ determinados, cada mensagem M~ n~ sendo codificada por meio de um código dinâmico C~ n~ próprio à data t~ n~ de envio da mensagem; - as mensagens recebidas pela plataforma são tratadas em função de sua data de recepção t~ r~ de modo que as mensagens recebidas em uma janela de observação F~ n~ nas proximidades de t~ n~ são decodificadas com uma seq³ência de decodificação DC~ n~ adaptada para decodificar o código dinâmico Cn, o relógio da plataforma receptora sendo escorada na data t~ 1~ ao recebimento da primeira mensagem M~ 1~.
