Randomly Rotate Qubits Compute and Reverse --- IT-Secure Non-Interactive Fully-Compact Homomorphic Quantum Computations over Classical Data Using Random Bases
Homomorphic encryption Quantum cryptography Information-theoretic security
<
2019/9/16
Homomorphic encryption (HE) schemes enable processing of encrypted data and may be used by a user to outsource storage and computations to an untrusted server. A plethora of HE schemes has been sugges...
Non-Interactive Zero Knowledge Proofs in the Random Oracle Model
FS transform NIZK random oracle model
<
2019/8/22
The Fiat-Shamir (FS) transform is a well known and widely used technique to convert any constant-round public-coin honest-verifier zero-knowledge (HVZK) proof or argument system CIPC=(Prov,Ver)CIPC=(P...
Decentralized Multi-authority Anonymous Authentication for Global Identities with Non-interactive Proofs
anonymous authentication attribute collusion attack
<
2019/6/14
We propose a decentralized multi-authority anonymous authentication scheme in which a prover and a verifier are non-interactive. We give two security definitions; resistance against collusion attacks ...
Black-Box Language Extension of Non-Interactive Zero-Knowledge Arguments
NIZK USS-NIZK black-box construction
<
2019/6/13
Highly efficient non-interactive zero-knowledge arguments (NIZK) are often constructed for limited languages and it is not known how to extend them to cover wider classes of languages in general. In t...
Simultaneous Amplification: The Case of Non-Interactive Zero-Knowledge
NIZK Security Amplification
<
2019/6/4
We develop novel techniques to leverage the use of leakage simulation lemma (Jetchev-Peitzrak TCC 2014) to argue amplification. A crucial component of our result is a new notion for secret sharing NPN...
DLSAG: Non-Interactive Refund Transactions For Interoperable Payment Channels in Monero
Linkable Ring Signature Payment Channel Blockchain
<
2019/6/3
Monero has emerged as one of the leading cryptocurrencies with privacy by design. However, this comes at the price of reduced expressiveness and interoperability as well as severe scalability issues. ...
Non-Interactive MPC with Trusted Hardware Secure Against Residual Function Attacks
Non-Interactive MPC Communication round complexity Trusted hardware
<
2019/5/9
Secure multiparty computation (MPC) has been repeatedly optimized, and protocols with two communication rounds and strong security guarantees have been achieved. While progress has been made construct...
A Note on Key Agreement and Non-Interactive Commitments
Non-interactive commitments key agreement
<
2019/3/13
We observe that any key agreement protocol satisfying perfect completeness, regardless of its round complexity, can be used to construct a non-interactive commitment scheme.
Non-interactive Cryptographic Timestamping based on Verifiable Delay Functions
non-interactive cryptographic timestamping universal composability verifiable delay functions
<
2019/3/1
We present the first treatment of non-interactive publicly-verifiable timestamping schemes in the Universal Composability framework. Similar to a simple construction by Mahmoody et al., we use non-par...
Non-Interactive Keyed-Verification Anonymous Credentials

2019/2/27
Anonymous credential (AC) schemes are protocols which allow for authentication of authorized users without compromising their privacy. Of particular interest are non-interactive anonymous credential (...
Efficient Non-Interactive Zero-Knowledge Proofs in Cross-Domains without Trusted Setup
public-key cryptography zero knowledge
<
2019/1/26
With the recent emergence of efficient zero-knowledge (ZK) proofs for general circuits, while efficient zero-knowledge proofs of algebraic statements have existed for decades, a natural challenge aros...
Non-Interactive Zero Knowledge and Correlation Intractability from Circular-Secure FHE
NIZK LWE
<
2019/1/4
We construct non-interactive zero-knowledge (NIZK) arguments for NPNP from any circular-secure fully homomorphic encryption (FHE) scheme. In particular, we obtain such NIZKs under a circular-secure va...

2018/11/7
We consider the problem of Non-Interactive Secure Computation (NISC), a 2-message ``Sender-Receiver'' secure computation protocol that retains its security even when both parties can be malicious. Whi...
