A Framework for UC-Secure Commitments from Publicly Computable Smooth Projective Hashing
UC commitment smooth projective hash function SPHF
2019/9/23
Hash proof systems or smooth projective hash functions (SPHFs) have been proposed by Cramer and Shoup (Eurocrypt'02) and can be seen as special type of zero-knowledge proof system for a language. Whil...
CrypTFlow: Secure TensorFlow Inference
secure multi-party computation implementation TensorFlow
2019/9/19
We present CrypTFlow, a first of its kind system that converts TensorFlow inference code into Secure Multi-party Computation (MPC) protocols at the push of a button. To do this, we build three compone...
On Fully Secure MPC with Solitary Output
Multi-Party Computation Full Security Dishonest Majority Malicious Adversaries
2019/9/17
We study the possibility of achieving full security, with guaranteed output delivery, for secure multiparty computation of functionalities where only one party receives output, to which we refer as so...
Post-Quantum Variants of ISO/IEC Standards: Compact Chosen Ciphertext Secure Key Encapsulation Mechanism from Isogenies
Post-quantum cryptosystems Isogeny-based cryptosystems CSIDH
2019/9/17
ISO/IEC standardizes several chosen ciphertext-secure key encapsulation mechanism (KEM) schemes in ISO/IEC 18033-2. However, all ISO/IEC KEM schemes are not quantum resilient. In this paper, we introd...
Simple and Efficient KDM-CCA Secure Public Key Encryption
key dependent message security chosen ciphertext security
2019/9/16
We propose two efficient public key encryption (PKE) schemes satisfying key dependent message security against chosen ciphertext attacks (KDM-CCA security). The first one is KDM-CCA secure with respec...
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...
Efficient Tightly-Secure Structure-Preserving Signatures and Unbounded Simulation-Sound QA-NIZK Proofs
Structure-preserving signatures QA-NIZK simulation-soundness
2019/9/16
We show how to construct structure-preserving signatures (SPS) and unbounded quasi-adaptive non-interactive zero-knowledge (USS QA-NIZK) proofs with a tight security reduction to simple assumptions, b...
An efficient and secure ID-based multi-proxy multi-signature scheme based on lattice
multi-proxy multi-signature scheme multi-signature scheme ID-based signature
2019/9/16
Multi-proxy multi-signature schemes are useful in distributed networks, where a group of users cooperatively could delegate their administrative rights to the users of another group, who are authorize...
CCA-Secure Leakage-Resilient Identity-Based Key-Encapsulation from Simple (not $\mathtt{q}$-type) Assumptions
public-key cryptography leakage-resilient identity-based encryption
2019/8/30
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...
Structure-Preserving and Re-randomizable RCCA-secure Public Key Encryption and its Applications
public-key cryptography Rand-RCCA PKE
2019/8/22
Re-randomizable RCCA-secure public key encryption (Rand-RCCA PKE) schemes reconcile the property of re-randomizability of the ciphertexts with the need of security against chosen-ciphertexts attacks.

Lattice based cryptography side-channel attacks CCA transformation
2019/8/21
In this article, we demonstrate practical side-channel assisted chosen-ciphertext attacks (CCA) over multiple CCA-secure lattice-based public-key encryption schemes (PKE) and key-encapsulation mechani...
