Abstract

criptografia da mensagem de enlace ascendente programada em procedimento de acesso aleatório sistemas e metodologias que facilitam o emprego de um procedimento de acesso aleatório que alavanca os dados criptografados e/ou decriptografados em uma mensagem de enlace ascendente programada, são descritos. um preâmbulo de acesso aleatório pode ser enviado a partir de um terminal de acesso para uma estação base, e uma resposta de acesso aleatório pode ser enviada da estação base para o terminal de acesso. uma mensagem de transmissão programada pode ser envida a partir do terminal de acesso para a estação base com base em uma concessão incluída na respostade acesso aleatório. quando o acesso aleatório com base em contenção é empregado, a mensagem de transmissão programada ou uma parte da mesma pode ser decriptografada. adicionalmente a informação não crítica de segurança pode ser enviada de forma decriptografada na mensagem de transmissão programada, enquanto a informação crítica de segurança pode ser criptografada para transmissão (por exemplo, incluída em uma parte criptografada da mensagem de transmissão programada e/ou transmitida em uma mensagem de transmissão programada normal criptografada subsequente).
