Abstract
aspectos revelados na descrição detalhada incluem motor criptográfico em linha (ice) para expresso de interconexão de componente periférico (pcie). a esse respeito, em um aspecto, um ice é fornecido em um complexo de raiz (rc) pcie em um sistema host. o rc pcie é configurado para receber ao menos um pacote de camada de transporte (tlp), que inclui um prefixo de tlp, de um dispositivo de armazenagem. em um exemplo não limitador, o prefixo de tlp inclui informações específicas de transação que podem ser usadas pelo ice para fornecer criptografia e decriptografia de dados. por fornecer o ice no rc pcie e receber as informações específicas de transação no prefixo tlp, é possível criptografar e decriptografar dados no rc pcie em conformidade com padrões estabelecidos, desse modo assegurando proteção adequada durante troca de dados entre o rc pcie e o dispositivo de armazenagem.
