摘要
数字版权管理是网络环境下数字内容交易和传播的重要技术。大多数数字作品供应商采用基于DRM的加密和认证技术来反盗版。本文提出一种基于虚拟机可信平台的数字版权管理方案。该方案基于TCG的可信计算平台保证生成信任链;使用Terra架构保证系统的隔离性、安全性并能将使用的内容向远端认证,保证数字文件在授权范围内使用,防止复制传播。
Digital rights management is an important technology for trade and dissemination of digital content in the network environment,most digital assets providers fight against unauthorized copying and recording by encryption and attestation technologies based on DRM,which can barely eradicate piracy.This paper applies Terra,an improved architecture of virtual machine,for DRM implementation.In our solution,Terra architecture guarantees the isolation,security and the remote content authentication of the system.TCG trusted computing platform enhanced the security of the system.The case study shows that,our DRM system can better prevent replay attacks and other vulnerabilities.
