Abstract

autenticação de texto sem formatação e texto cifrado em uma mensagem veículo para tudo (v2x). os métodos, dispositivos e sistemas para implementar os métodos para autenticação de texto sem formatação e texto cifrado em uma mensagem de veículo para tudo (v2x) incluem gerar texto cifrado de uma mensagem de texto sem formatação a ser transmitida em uma mensagem v2x, gerar um hash do texto cifrado e um hash da mensagem de texto sem formatação, gerar uma assinatura digital de uma concatenação do hash do texto cifrado e o hash da mensagem de texto sem formatação e enviar para um nó de rede uma mensagem v2x que inclui o texto cifrado, o hash da mensagem de texto sem formatação e a assinatura digita. o hash da mensagem de texto sem formatação e a assinatura digital podem ser configurados para permitir que o nó da rede verifique se o nó do ponto de terminação v2x assinou a concatenação.
