Abstract

no sistema operacional hospedeiro de um dispositivo de computação, dados de entropia são coletados com base pelo menos em parte em cada um dentr um ou mais componentes de hardware do dispotivo de computação. um conjunto de entropia é atualizado com base pelo menos em parte nos dados de entripia coletados, e dados a partir do conjunto de entropia são fornecidos a um sistema operacional hóspede que está em execução como uma máquina virtual do dispositivo de computação. o sistema operacional hóspede mantém um conjunto de entropia fornecidos pelo sistema operacional hospedeiro. o sistema operacional hóspede acessa o conjunto de entropia de sistema operacional hóspede e utiliza o conjunto de entropia de sistema operacional hóspede como uma base para gerar valores que incluem números aleatórios.
