| 摘 要： | 基于压缩编码的加密方式能够同时完成加密和压缩的功能，通过压缩减少了信息的冗余，同时引入加密使对试图推测出明文信息和找到密钥的攻击具有非常好的鲁棒性。提出了一种基于随机区间置换的安全算术编码，在编码过程中通过随机密钥保证图像压缩编码的安全性，且不影响编码的效率，使其方便在网络中安全传输。实验结果和安全性分析表明该安全算术编码有较好的安全性和加密效率。

| Abstract: | Encryption based on compression can provide compression and encryption in a single step, in which redundancy is removed by compression and security is guaranteed by encryption. A novel secure arithmetic coding scheme based on interval exchanging is proposed in this paper, and it is applied to image encryption. It's found images can be transmitted securely on the Internet and the proposed algorithm dose not bring extra expense in terms of coding efficiency. Experimental results and security analyses indicate that the algorithm has good security strength as well as high encryption efficiency. |
