IoT-Friendly AKE: Forward Secrecy and Session Resumption Meet Symmetric-Key Cryptography
Security protocols Authenticated key exchange Symmetric-key cryptography
2019/8/13
With the rise of the Internet of Things and the growing popularity of constrained end-devices, several security protocols are widely deployed or strongly promoted (e.g., Sigfox, LoRaWAN, NB-IoT). Base...
Scalable Private Set Union from Symmetric-Key Techniques
Private Set Union Private Membership Test
2019/7/4
We present a new efficient protocol for computing private set union (PSU). Here two semi-honest parties, each holding a dataset of known size (or of a known upper bound), wish to compute the union of ...
Symmetric-key Authenticated Key Exchange (SAKE) with Perfect Forward Secrecy
Authenticated key agreement Symmetric-key cryptography Perfect forward secrecy
2019/5/9
Key exchange protocols in the asymmetric-key setting are known to provide stronger security properties than protocols in symmetric-key cryptography. In particular, they can provide perfect forward sec...

Side-Channel Attacks Deep Learning Machine Learning
2019/2/26
Deep Neural Networks (DNNs) have recently received significant attention in the side-channel community due to their state-of-the-art performance in security testing of embedded systems. However, resea...
Applications of H-Technique: Revisiting Symmetric Key Security Analysis
provable security coefficients H technique Feistel
2018/11/29
The Coefficients H Technique (also called H-technique), by Patarin, is a tool to obtain upper bound on the distinguishing advantage. The tool is known for providing quite simpler and tight bound proof...
DiSE: Distributed Symmetric-key Encryption
Threshold Cryptography Authenticated Encryption
2018/8/10
Threshold cryptography provides a mechanism for protecting secret keys by sharing them among multiple parties, who then jointly perform cryptographic operations. An attacker who corrupts upto a thresh...
Post-Quantum Zero-Knowledge Proofs for Accumulators with Applications to Ring Signatures from Symmetric-Key Primitives
privacy-preserving cryptography provable security accumulator
2017/11/29
In this paper we address the construction of privacy-friendly cryptographic primitives for the post-quantum era and in particular accumulators with zero-knowledge membership proofs and ring signatures...
Cryptanalysis against Symmetric-Key Schemes with Online Classical Queries and Offline Quantum Computations
post-quantum cryptography classical query model meet-in-the-middle
2017/10/9
In this paper, quantum attacks against symmetric-key schemes are presented in which adversaries only make classical queries but use quantum computers for offline computations. Our attacks are not as e...
Lightweight Symmetric-Key Hidden Vector Encryption without Pairings
Hidden Vector Encryption Symmetric-Key Simulation-Security
2017/8/28
Hidden vector encryption (HVE), introduced by Boneh and Waters in TCC'07, is an expressive sub-class of predicate encryption, that allows conjunctive, subset, range and comparison queries over encrypt...
Practical Multi-party Private Set Intersection from Symmetric-Key Techniques
Private Set Intersection Oblivious PRF Secure Multiparty Computation
2017/8/28
We present a new paradigm for multi-party private set intersection (PSI) that allows nn parties to compute the intersection of their datasets without revealing any additional information. We explore a...
Post-Quantum Zero-Knowledge and Signatures from Symmetric-Key Primitives
post-quantum cryptography zero-knowledge signatures
2017/3/31
In our signature constructions, the public key is an image y=f(x) of a one-way function f and secret key x. A signature is a non-interactive zero-knowledge proof of x, that incorporates a message to b...

Errors Assumption Symmetric-Key Bit Encryption
2017/2/20
In this work we separate private-key semantic security from circular security using the Learning with Error assumption. Prior works used the less standard assumptions of multilinear maps or indistingu...

2016/12/7
We propose practically efficient signature schemes which feature several attractive properties: (a) they only rely on the security of symmetric-key primitives (block ciphers, hash functions), and are ...
