摘　　要：高安全性、高效率的加密算法是大型计算应用的重要保障条件之一。文中结合混合加密算法和属性基加密算法提出了一种监控网络安全接入模型设计方案。混合加密算法由ECC和AES组成,通过采用窗口块NAF算法对ECC进行改进,使得算法效率得到提升,利用AES算法,进一步缩短了加解密时间。同时,使用CP-ABE算法实现了细粒度的访问控制,提升了数据的安全性。在实验测试中,算法加解密时间在所有对比算法中为最短,且破译所需时间长达1020年,能够有效保证监控网络的数据传输安全。A highly secure and efficient encryption algorithm is one of the important guarantee conditions for large-scale computing applications.A design scheme for a monitoring network security access model is proposed in the article,which combines hybrid encryption algorithms and attribute based encryption algorithms.The hybrid encryption algorithm consists of ECC and AES.By using the window block NAF algorithm to improve ECC,the efficiency of the algorithm is improved.At the same time,the AES algorithm is used to further shorten the encryption and decryption time.At the same time,the CP-ABE algorithm was used to achieve fine-grained access control and improve data security.In the experimental testing,the encryption and decryption time of the algorithm was the shortest among all compared 20 algorithms,and the decryption time was as long as 10 years,which can effectively ensure the data transmission security of the monitoring network.
