| 摘 要： | 现有的无证书广播加密方案是向用户传输相同的信息量,没有权限的概念。基于哈夫曼树,引入权值,提出了一种新的无证书公钥广播加密方案,实现了对不同权限的用户传输不同的信息量。与已有的广播方案相比,该方案平均计算密钥量少,降低了通信开销,灵活性更高。

| Abstract: | The existing certificateless broadcast encryption scheme transfers the same information to users,without the concept of permission.Based on Huffman tree and the permission,a new certificateless public broadcast encryption scheme is proposed.It can transfer different information to different permissions users.Compared with existing broadcast scheme,the new scheme has little average key calculation,higher flexibility and reduces the communicational cost. |
