在一种三层结构的家庭网络组网结构中,使用广播加密算法以实现客户的认证以及文件和流媒体内容的传输。借鉴一种已经提出的广播加密方案,基于Tate配对性质的HIBE算法进行改进,可以抵御重放攻击,防止密钥泄漏。
This paper describes a scheme to use broadcast encryption on a three-layer home network structure. The idea based on pre-distributed symmetric keys,which with minimal reliance on public key cryptographic operations. The architecture not require continuous network connectivity on devices. It allows efficient and flexible key updating and revocation.
