Abstract

"SISTEMA INCLUINDO UMA PLURALIDADE DE DISPOSITIVOS, E, PRIMEIRO DISPOSITIVO SENDO DESIGNADO COM UM IDENTIFICADOR DE DISPOSITIVO". Em autenticação baseada em lista branca, um primeiro dispositivo (102) em um sistema (100) se autentica para um segundo dispositivo (103) usando um certificado de grupo identificando uma gama de identificadores de dispositivo não revogado, dita gama abrangendo o identificador de dispositivo do primeiro dispositivo (102). Preferivelmente, os identificadores de dispositivo correspondem a nós de folha em uma árvore hierarquicamente ordenada, e o certificado de grupo identifica um nó (202207) na árvore representando uma subárvore na qual os nós de folha correspondem à dita gama. O certificado de grupo também pode identificar um nó adicional (308, 310, 312) na subárvore, que representa uma subárvore na qual os nós de folha correspondem a identificadores de dispositivo revogado. Alternativamente, os identificadores de dispositivo são selecionados de uma gama seq³encialmente ordenada, e o certificado de grupo identifica uma sub-gama da gama seq³encialmente ordenada, dita sub-gama abrangendo os identificadores de dispositivo listado em branco.
