| 摘 要： | 广播加密是一种应用广泛的群组安全通信方案，在付费有线电视、在线数据库和无线传感网络等场合具有良好的应用前景．文章根据Stinson的广播加密思想，提出用正交阵列构造的强部分平衡不完全区组设计来构造广播加密方案．该新方案在抵御合谋攻击上有明显优势．文章最后还提出用对偶设计改进方案的广播信息率．

| Abstract: | Broadcast encryption scheme is a widely used cryptosystem for a group of receivers,such as pay-TV,online-database,wireless and sensor networks etc.In this paper,we analyzed the general broadcast encryption scheme and proposed a broadcast encryption scheme using the strong part of the balanced incomplete block design constructed by orthogonal arrays.The new scheme has obvious advantages in resisting the collusion attack.Finally the broadcast information rate is improved with dual designs as well. |
