最近，Wang等人提出了一种有效的基于Logistic映射的分组加密系统。该加密系统采用反馈密文来实现子密钥的明文依赖性。不幸的是，我们发现他们的方案无法抵御密钥流攻击。为了提高其安全性，提出了一种新的基于混沌映射的分组密码系统。同时，构建了一个摄像机传感器网络的安全体系结构。该网络包括一组廉价的摄像机传感器来捕获图像，一个汇聚节点配备有足够的计算和存储能力和数据处理服务器。利用改进的密码算法，保证了汇聚节点与服务器之间的传输安全。理论分析和仿真结果表明，改进后的算法能够克服原密码体制的缺陷，并保持原密码体制的所有优点。此外，所提出的方案的计算成本和效率是令人鼓舞的实际实施在真实的环境以及摄像机传感器网络。
Recently, Wang et al. presented an efficient logistic map based block encryption system. The encryption system employs feedback ciphertext to achieve plaintext dependence of sub-keys. Unfortunately, we discovered that their scheme is unable to withstand key stream attack. To improve its security, this paper proposes a novel chaotic map based block cryptosystem. At the same time, a secure architecture for camera sensor network is constructed. The network comprises a set of inexpensive camera sensors to capture the images, a sink node equipped with sufficient computation and storage capabilities and a data processing server. The transmission security between the sink node and the server is gained by utilizing the improved cipher. Both theoretical analysis and simulation results indicate that the improved algorithm can overcome the flaws and maintain all the merits of the original cryptosystem. In addition, computational costs and efficiency of the proposed scheme are encouraging for the practical implementation in the real environment as well as camera sensor network.
