基于RSA及Paillier的网络数据传输隐私保护

Network Data Transmission Privacy Protection Based on RSA and Paillier

为提升网络数据传输安全性,减少被窃取、攻击以及丢失的概率,杜绝隐私信息泄露和严重经济损失事件发生,提出一种基于RSA及Paillier的网络数据传输隐私保护方法,利用数据包接收端将数据收集齐,再通过节点本身确认需求发送数据包传输请求的邻居节点,建立网络数据传输模型,并通过RSA的公、私钥乘除获得网络密文熵。同时,由于Paillier拥有加法及混合乘法同态性质,可利用公、私钥加、减获得网络密文熵,最后服务器接收到数据信息,加密数据中的常数,获得最终的隐私保护。仿真结果证明,所提方法隐匿率较小,但隐私保护效果好,鲁棒性优秀。

This paper presents a privacy protection method of network data transmission based on RSA and Paillier for improving the security of network data transmission, lowing the probability of theft, attack and loss. Firstly, according to the packet receiver, the data were completely collected. Then, based on the node, the neighbor node that needs to send the packet transmission request was confirmed to establish the network data transmission model. The entropy of network ciphertext was obtained through multiplication and division of RSA public key and private key. Secondly, the entropy of network ciphertext was obtained by adding and subtracting public and private keys owing to the homomorphism of addition and mixed multiplication of Paillier. Eventually, the data information was received by the server, and the constants in the data were encrypted, thus obtaining the final privacy protection. The simulation results show that the method has small concealment rate, excellent privacy protection effect and outstanding robustness.
