We broadly classify these secure aggregation protocols into three categories based on the techniques they use: Secret Sharing-based protocols, Differential Privacy-based protocols, and Homomorphic Encryption-based protocols. The classification is shown in TABLE 2. The advantages and disadvantages of the three techniques are statistically presented in TABLE 3. Looking at this Table 3,[0.5õ©] the highest cost is homomorphic encryption, and of course, his nature will be the best. Next is secret sharing and differential privacy. And then neither of the two techniques except differential privacy leads to accuracy loss. And then only secret sharing requires protocol redesign. And for the robustness of dropout, only secret sharing supports it. |
