Abstract

TRANSMISSãO EFICIENTE DE INFORMAçõES CRIPTOGRáFICAS EM PROTOCOLO SEGURO EM TEMPO REAL Trata-se da transmissão eficiente de informações criptográficas em protocolo seguro em tempo real. Um terminal de transmissão pode ser utilizado para criptografar dados com uma chave de sessão derivada de um fluxo de bits. O fluxo de bits pode ser enviado com informações de cabeçalho ao terminal de recepção. Para se conservar a largura de banda, as informações podem ser divididas em partes, e cada parte transmitida com um pacote de dados criptografado. O terminal de recepção pode ser utilizado para recuperar o fluxo de bits das partes de informação nos cabeçalhos de pacote, e utilizar o fluxo de bits para derivar a chave de sessão. A chave de sessão pode ser utilizada para decriptografar os dados.
