While initially used to build efficient chosen-ciphertext secure public-key encryption, they found numerous applications in several other contexts. In this paper, we revisit the notion of SPHFs and introduce a new feature (a third mode of hashing) that a

On the positive side, in the best case, they showed that one can achieve subversion zero-knowledge (zero-knowledge without trusting to the

In this work, we present an efficient and versatile framework for oblivious transfer (OT) using one-round key-exchange (ORKE), a special class of key exchange (KE) where only one message is sent from each party to the other. Our contributions can be summarized as follows:.Examples are pre

Unfortunately, this also makes it easier for users to share protected data by simply sharing decryption keys..Kiayias and Tang (ACM CCS 2013) were the first to address this important issue pre-emptively rather than a posteriori like traitor tracing schemes do. They proposed . encryption sch

Computational Models of Vortex Wakeignature schemes in a relatively straight forward manner. We conclude that all schemes, except the ones in the MQ family, have significant issues when one wishes to convert them using relatively generic MPC techniques. The lattice based schemes are hampered by requiring a mix of operations which are

We study the possibility of replacing the well-known preprocessing model with a commodity-based setting, where a set of . servers (some of which may be corrupt) provide clients with correlated randomness. From this, the clients then distill correct and secure corre
