When Homomorphic Encryption Marries Secret Sharing: Secure Large-Scale Sparse Logistic Regression and Applications in Risk Control [article]

Chaochao Chen, Jun Zhou, Li Wang, Xibin Wu, Wenjing Fang, Jin Tan, Lei Wang, Alex X. Liu, Hao Wang, Cheng Hong
2021 arXiv   pre-print
In this paper, we first present CAESAR, which combines HE and SS to build secure large-scale sparse logistic regression model and achieves both efficiency and security.  ...  Most existing work uses either Homomorphic Encryption (HE) or Secret Sharing (SS) to build secure LR.  ...  We present CAESAR, a seCure lArge-scalE SpArse logistic Regression model by marrying HE and SS.  ...
