Nas redes de sensores sem fios (WSNs), é necessário estabelecer chaves secretas partilhadas com os nós vizinhos para garantir uma comunicação segura. A gestão de chaves e a segurança são questões desafiantes nas WSN. A gestão de chaves dependente da localização (LDK) é um esquema adequado quando comparado com outros esquemas de gestão de chaves baseados na localização, devido à grande necessidade de espaço de memória e ao maior número de chaves a armazenar em cada nó do sensor. No entanto, o LDK é afetado pelo problema de interferência de comunicação, que é resolvido pela chave distribuída com base no modelo de confiança. Os processos de atualização e revogação de chaves para resistir eficazmente a atacantes internos. O método proposto pode aumentar a conectividade e, ao mesmo tempo, diminuir a taxa de comprometimento quando o número mínimo de chaves comuns necessárias para o estabelecimento de chaves. Os modelos de confiança foram propostos como um mecanismo de segurança eficaz para WSNs.
