Data privacy protection based on homomorphic encryption

Abstract

Data security and privacy protection are increasingly becoming a bottleneck in the development of cloud computing. To improve the existing homomorphic encryption technology, ECC homomorphic encryption algorithm is proposed, and ECC homomorphic encryption algorithm is designed and implemented. Based on this, the aggregation model of data privacy protection is constructed, and the effect of ECC homomorphic encryption data security operation is analyzed. Compared with the traditional RSA encryption algorithm, ECC homomorphic encryption algorithm shows a higher level of security. When the key length increases gradually, the security of ECC with more than 300 bits is much greater than that of RSA with more than 2000 bits. At the same time, ECC homomorphic encryption algorithm is better than RSA in terms of encryption time and cipher size. ECC homomorphic encryption algorithm has the advantages of low computational complexity and good security performance.
