Abstract

São descritos sistemas e métodos associados que envolvem um dispositivo confiável e um dispositivo não confiável onde os dados sensíveis ou chaves são compartilhados entre esses dispositivos. Um método revelado inclui armazenar uma chave em uma memória segura em um primeiro dispositivo, receber dados sensíveis através de uma interface de usuário em um segundo dispositivo, gerar um conjunto de instruções de encriptação de caixa branca com base na chave usando um gerador de encriptação de caixa branca no primeiro dispositivo, gerar uma representação de dados completa do conjunto de instruções de encriptação de caixa branca usando um processador seguro no primeiro dispositivo, transmitir a representação de dados completa a partir do primeiro dispositivo ao segundo dispositivo, e encriptar os dados sensíveis usando a representação de dados completa no segundo dispositivo. A representação de dados completa não é Turing-completa e não é executável em relação ao segundo dispositivo.
