摘　　要：针对现有加密方法对数据篡改攻击的抵抗能力较差的问题,设计一种数据篡改攻击下配电网络传输数据安全加密方法。根据数据篡改攻击的类型,结合GEP算法对配电网络传输的数据作过滤处理,并在过滤处理中去除混入的攻击数据包;应用ECC-AES结合算法对数据明文进行加密,即先使用AES算法将数据明文变换成密文和密钥,再利用ECC算法对密文和密钥再次加密;将加密后的密钥、密文以及签名块传输至数据接收端,在接收端对密文进行解密,实现数据篡改攻击下配网数据的安全加密。对比实验结果可知,该数据加密方法对数据篡改攻击的抵抗能力较强,具有较高的应用性能。Aiming at the problem that the existing encryption methods have poor resistance to data tamper attack,a secure encryption method for transmission data in distribution network under data tamper attack is designed.According to the type of data tamper attack,the data transmitted by distribution network is filtered by GEP algorithm,and the attack packets are removed in the filtering process.The data plaintext is encrypted by ECC-AES algorithm,that is,the data plaintext is transformed into ciphertext and key by AES algorithm,and the ciphertext and key are encrypted again by ECC algorithm.The encrypted key,ciphertext and signature block are transmitted to the data receiving end,where the ciphertext is decrypted to realize the security encryption of distribution network data under the data tampering attack.Compared with the experimental results,the data encryption method has strong resistance to data tamper attack and has high application performance.
