Abstract

"MéTODO E EQUIPAMENTO PARA TRANSMISSãO DE DADOS SEGURA EM UM SISTEMA DE COMUNICAçãO MóVEL". São descritos um método e um equipamento para transmissões seguras. Cada usuário é provido com uma chave de registro. Uma chave de irradiação atualizada de longo prazo é codificada usando-se a chave de registro e é provida periodicamente a um usuário. Uma chave atualizada de curto prazo é codificada usando-se a chave de irradiação e é provida periodicamente a um usuário. As irradiações são então codificadas usando-se a chave de curto prazo, em que o usuário decodifica a mensagem de irradiação usando a chave de curto prazo. Uma modalidade provê codificação de conteúdo de camada de link. outra modalidade provê codificação ponta a ponta.
