In this paper, we propose a new leakage-resilient identity-based encryption (IBE) scheme that is secure against chosen-ciphertext attacks (CCA) in the bounded memory leakage model. It is the first CCA...
A traitor tracing scheme is a multi-user public-key encryption scheme where each user in the system holds a decryption key that is associated with the user's identity. Using the public key, a content ...
The security proofs for isogeny-based undeniable signature schemes have been based primarily on two isogeny hardness assumptions: that the One-Sided Modified SSCDH problem and the One-More SSCDH probl...
Functional encryption (FE) that bases on user attributes has many useful practical applications. For example, a company may only authorize department heads of other sections to query the average sale ...
Non-zero inner product encryption (NIPE) allows a user to encrypt a message with its attribute vector and decryption is possible using a secret-key associated with a predicate vector if the inner prod...
A non-interactive zero-knowledge (NIZK) protocol allows a prover to non-interactively convince a verifier of the truth of the statement without leaking any other information. In this study, we explore...
We construct a broadcast and trace scheme (also known as trace and revoke or broadcast, trace and revoke) with NN users, where the ciphertext size can be made as low as O(Nϵ)O(Nϵ), for any...
Cryptocurrency applications have spurred a resurgence of interest in the computation of ECDSA signatures using threshold protocols---that is, protocols in which the signing key is secret-shared among ...
We propose Lelantus, a new anonymous payment system which ensures both transaction confidentiality and anonymity with small proof sizes, short verification times and without requiring a trusted setup.
We put forth a new class of search problems, iterated search problems (ISP), and study their relation to the design of secure blockchain protocols. We prove that (i) any blockchain protocol implies a ...
In a non-interactive zero-knowledge (NIZK) proof, a prover can non-interactively convince a verifier of a statement without revealing any additional information. Thus far, numerous constructions of NI...
Ring signatures allow for creating signatures on behalf of an ad hoc group of signers, hiding the true identity of the signer among the group. A natural goal is to construct a ring signature scheme fo...
There is surprisingly little consensus on the precise role of the generator g in group-based assumptions such as DDH. Some works consider g to be a fixed part of the group description, while others ta...
In this work we continue the study on the round complexity of secure multi-party computation with black-box simulation in the simultaneous broadcast model where all the parties get the output.
We study the problem of constructing secure multiparty computation (MPC) protocols in the standard broadcast communication model from {\em minimal} assumptions. We focus on security in the plain model...
