WebAlthough achieving anonymity can be an important design criterion in cryptographic systems, it comes at a cost. If the systems are not carefully designed, the overall security of the system could be compromised. Our goal is to develop mathematical techniques that enable anonymity in cryptographic systems without compromising the security. 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].

WebAbstract. Decentralized anonymity infrastructures are still not in wide use today. While there are technical barriers to a secure robust design, our lack of understanding of the incentives to participate in such systems remains a major roadblock.
