摘　　要：文章通过实验研究,评估Scapy框架在检测网络漏洞及结合高级加密标准(Advanced Encryption Standard,AES)与RSA加密算法进行通用面向对象变电站事件(Generic Object Oriented Substation Event,GOOSE)消息混合加解密保护效果方面的表现。实验成功发现并记录多种不同程度的网络漏洞,验证Scapy框架的准确性和适应性。同时,实验结果证明该加解密方案能够有效保护通信内容,且在实际通信场景中对性能的影响较小。综合实验结果可知,该方案在变电站监控系统中具有一定的实际应用潜力,为网络漏洞防护提供了可行的解决方案。Through experimental research,this paper evaluates the performance of Scapy framework in detecting network vulnerabilities and combining Advanced Encryption Standard(AES)and RSA encryption algorithm to protect the mixed encryption and decryption of General Object Oriented Substation Event(GOOSE)messages.The experiment successfully found and recorded a variety of network vulnerabilities in different degrees,and verified the accuracy and adaptability of Scapy framework.At the same time,the experimental results prove that the encryption and decryption scheme can effectively protect the communication content,and has little impact on the performance in the actual communication scenario.The comprehensive experimental results show that the scheme has certain practical application potential in substation monitoring system and provides a feasible solution for network vulnerability protection.
