中文摘要:

在电网系统中,隐私信息的加密需要确保高度安全性,以防止数据泄露或被未授权访问。多重嵌入技术要求加密算法足够复杂,以抵御各种攻击,如暴力破解、侧信道攻击等。但是,当隐私聚合在一个层级时, 其风险不具有分散性,被攻破的可能性更大。为此, 研究一种电网密文域多重嵌入隐私信息多层级分区加密方法。研究中利用K-means算法对隐私信息进行多层级分区,多层级分区可以将风险分散到不同的层级。如果某个层级的安全措施被攻破,其他层级的数据仍然可以得到保护。这种风险分散机制可以减少单点故障对整个系统安全性的影响。通过Logistic映射生成密钥序列,利用密钥对所有电网密文域多重嵌入隐私信息完成初次加密,得到密文。利用Paillier半同态加密算法对分区敏感性高的电网密文域多重嵌入隐私信息密文实现二层加密。结果表明:面对不同攻击, 所研究方法的安全等级更高, 说明所研究的方法加密后的隐私信息更不容易被破解和窃取。

英文摘要:

In the power system, the encryption of privacy information needs to ensure high security to prevent data leakage or unauthorized access. Multiple embedding technology requires encryption algorithms to be complex enough to resist various attacks, such as brute force cracking and side channel attacks. However, when privacy is aggregated at one level, its risk is not dispersed and the likelihood of being compromised is greater. To this end, a multi-level partitioning encryption method for multiple embedded privacy information in the encrypted text domain of power grid is studied. In the study, the K-means algorithm was used to partition privacy information at multiple levels, which can disperse risks to different levels. If security measures at one level are compromised, data at other levels can still be protected. This risk diversification mechanism can reduce the impact of a single point of failure on the overall system security. A key sequence is generated through Logistic mapping, and the key is used to embed privacy information multiple times in all power grid encrypted text domains for initial encryption, obtaining the encrypted text. The Paillier semi-homomorphic encryption algorithm is used to achieve two-layer encryption for multi-embedding privacy information encrypted texts in high partition sensitive power grid encrypted text domains. The results indicate that in the face of different attacks, the security level of the studied method is higher, indicating that the encrypted privacy information of the studied method is less likely to be cracked and stolen.
