摘要：

在统一通信异构网络环境中，由于统一的协议规范、加密以及防火墙等安全措施的存在，在网络环境内部进行的通信具有良好的可用性和安全性。当前的电力通信网，由于业务网络众多、网络层级明显，异构网络环境被广泛地应用在其通信的各个方面。但异构网络之间的通信，为了保证其可用性，安全性却被降低。在研究了异构网络穿越的问题和现状之后，又对对称密钥密码体制、非对称密钥密码体制进行了深入的研究，并且提出了一种基于RSA算法和改进型DES算法的混合加密算法。最后，运用实例分析表明，该算法具有很好的安全性。

Abstract:

Due to the unified protocol specification, encryption, and firewalls and other security measures at present, communication within the network environment are in good usability and security in heterogeneous network environment. However, in order to guarantee the availability, safety of the communication between heterogeneous networks has been reduced. Based on the study of heterogeneous networks through the issues and the status quo on the symmetric key cryptography, asymmetric key cryptosystem in-depth research, an encryption algorithm based on the RSA algorithm and improved DES algorithm was proposed. Finally, the use of case study shows that the algorithm has good security.
