Abstract：Asanewdistributed machine learning（DML）framework，F(xiàn)Lcanefectively protectthelocaldata privacyof participantsbyaggregatingthelocalmodelparametersuploadedbyparticipantstotraintheglobalmodel.However，theselocal model parameters still have the risk of revealing the privacy of participants. As a critical step in FL ， the privacy-preserving aggregation （ PPAgg ）mechanism has become a key technology for addressing privacy issues.This paper first introduced the concept of FL and its associated privacyand security threats.It then highlighted the core ideas and key proceduresof PPAgg mechanisms by integrating existing privacy-preserving techniques inFL.This paper analyzed typical PPAgg mechanisms indetail，focsingontheirprimaryadvantagesandlimitations，aswellasthespecificapplicationscenarioswhereheyweresuitable.Finall，this papersummarized andanalyzed curent PPAgg mechanisms，explored emerging challenges anddevelopment directions for FL ，and proposed potential solutions to address these issues.
