摘要

为了解决数字版权保护中的用户密钥泄漏问题

提出了一种基于双线性映射的叛逆者追踪方案.该方案采用双主密钥的群密钥分发策略来计算各用户的解密密钥

并基于超椭圆曲线上的双线性对构造加密、解密方案.这样

广播中心仅需传输3个群元素的控制报头信息

而在接收端的合法授权用户可以解密、恢复加密会话密钥.安全性分析结果表明

在逆Weil对假设和k-BDHI假设下

所提方案的抗合谋攻击性比较好

能够有效地对抗单用户匿名盗版攻击

也可以用来构造有效的公钥叛逆者追踪方案.

Abstract

A new efficient traitor tracing scheme using bilinear mapping is presented in order to solve the user-key leaking problem in digital right management. The group-key distribution strategy with double master keys is employed in the proposed scheme to compute the decryption key of each user

and the encryption and decryption algorithms are constructed based on bilinear pairings on super-singular elliptic curve. The broadcasting center only needs to broadcast a controlling header with three group elements

and the authorized users can correctly decrypt the broadcasting information and recover the session key. The security analysis shows that the proposed scheme can efficiently resist the k-collusion attack and the anonymous single-user pirate attack under inverse Weil-pairing assumption and k-BDHI assumption

and in addition

it can be used to construct efficient public key traitor tracing scheme.
