Abstract

MéTODO E APARELHO PARA CRIPTOGRAFIA DE COMUNICAçãO PELO AR EM SISTEMA DE COMUNICAçãO SEM FIO. Um dispositivo de comunicação (202) que converte um fluxo de bit para múltiplos simbolos e fornece criptograf ia em uma camada física através do deslocamento de uma fase de cada símbolo de simbolos múltiplos para produzir simbolos múltiplos criptografados. Cada símbolo criptografado dos múltiplos simbolos criptografados é modulado com uma sub-portadora ortogonal para produzir pelo menos uma sub-portadora modulada e de pelo menos uma sub-portadora modulada ser então transmitida através de um enlace sem fio. Em um lado de recepção, um dispositivo de comunicação de recepção (250) recebe os simbolos criptografados transmitidos e fornece descriptograf ia em uma camada física através do deslocamento de uma fase de cada símbolo criptografado em correspondência com a fase usada para criptografar o símbolo em um lado de transmissão.
