本文提出了一种抗共谋攻击的加密方法，用于具有分层可扩展性的 JPEG 2000 码流的访问控制。所提出的方法通过多维扫描从一个单一密钥生成一个加密密钥以服务加密并保持码流的可扩展性。为了避免多个用户从自己的密钥生成非法密钥以克服访问控制的共谋攻击，该方法考虑了充分的条件。此外，引入跳跃加密来降低加密的计算复杂性和密钥管理和传送成本。仿真结果表明了该方法的有效性。
This paper proposes a collusion attack-resilient method of encryption for access control of JPEG 2000 codestreams with hierarchical scalabilities. The proposed method generates one encryption key from one single key by multi-dimensional scanning to serve encryption keeping the scalability of codestrems. To avoid collusion attacks in which multiple users generate an illegal key from their own keys to overcome the access control, sufficient conditions are considered in this method. Moreover, a skip encryption is introduced to decrease the computational complexity and key management-and-de-livery cost of encryption. Simulation results show the effectiveness of the proposed method.
