Abstract

"COMUNICAçãO SEGURA COM UM TECLADO OU DISPOSITIVO RELACIONADO". Trata-se de comunicação segura entre um teclado e um componente, tal como uma peça de software executando em um computador. Um primeiro valor inicial é conhecido tanto pelo teclado como pelo componente. O teclado e o componente trocam palavras criadas para certa ocasião. Cada um dentre o teclado e o componente calcula um segundo valor inicial e um terceiro valor inicial baseado nas palavras criadas para certa ocasião e no primeiro valor inicial. Tanto o teclado como o componente executam o mesmo cálculo, de modo que cada um dentre o teclado e o componente possui os mesmos segundo e terceiro valores iniciais. o teclado criptografa os pressionamentos de tecla destinados para o componente utilizando o CBC-3DES baseado na chave e no segundo valor inicial e também cria um código de autenticação de mensagem para cada pressionamento de tecla utilizando o CBC-3DESMAC baseado na chave e no terceiro valor inicial. O componente decriptografa e verifica os pressionamentos de tecla utilizando a chave e o segundo e terceiro valores iniciais.
