Cryptography from anonymity

Web1.2 Anonymity and time in public-key encryption The importance of anonymity. Addressing the issue of protecting users’ privacy is of crucial importance. This is reflected by the great attention given to anonymity in all the main fields of modern cryptography. In the area of PKE, anonymity is often referred to as key-privacy [8]. WebThe paper’s claim is that using anonymity (the shuffler) we can get an improved dependence on m. So our focus is on overall communication complexity and not computation. At a …
