Abstract

"MéTODO PARA PROCESSAR DADOS". Método para processar dados, no qual uma rede de Petri é codificada, gravada em uma memória e lida e executada por pelo menos uma instância, onde transições da rede de Petri lêem a partir de pelo menos uma fita e / ou gravam em pelo menos uma fita símbolos ou cadeias de caracteres de símbolos, com a ajuda de pelo menos um cabeçote. ¢Fig. 1!. Em uma alternativa, redes de processamento de dados cooperativas são compostas, o resultado de composição é codificado, gravado em uma memória e lido e executado a partir da memória por pelo menos uma instância. Ao fazer isto, os componentes podem ter funções criptológicas. As redes de processamento de dados podem receber e processar os segundos dados a partir de uma função criptológica que é executada de um modo protegido. A invenção permite o processamento de dados, o que impede a análise semântica de possivelmente poucas etapas de processamento expostas e que pode produzir uma ligação das etapas de processamento com um hardware que seja difícil de se isolar.
