Security in the Internet of Things (IoT) is challenging. The need for lightweight yet robust cryptographic solutions suitable for the IoT calls for improved design and implementation of constructs suc...
Privacy and Reader-first Authentication in Vaudenay's RFID Model with Temporary State Disclosure
RFID scheme PUF authentication
2019/2/27
Privacy and mutual authentication under corruption with temporary state disclosure are two significant requirements for real-life applications of RFID schemes. No RFID scheme is known so far to meet t...
Compressive Sensing based Leakage Sampling and Reconstruction: A First Study
compressive sensing matching pursuit OMP
2018/12/3
An important prerequisite for Side-channel Attack (SCA) is leakage sampling where the side-channel measurements (e.g. power traces) of the cryptographic device are collected for further analysis. Howe...

Authenticated Encryption KETJE SHA-3
2018/11/19
Recently the CAESAR competition has announced several finalists among the submitted authenticated encryption algorithms, after an open selection process during the last 5 years. Applications using the...
Yet Another Size Record for AES: A First-Order SCA Secure AES S-box Based on GF($2^8$) Multiplication
side-channel analysis Threshold Implementation AES
2018/11/12
It is well known that Canright’s tower field construction leads to a very small, unprotected AES S-box circuit by recursively embedding Galois Field operations into smaller fields. The current size re...

A First-Order SCA Resistant AES without Fresh Randomness
side-channel analysis threshold implementation randomness
2018/3/6
Since the advent of Differential Power Analysis (DPA) in the late 1990s protecting embedded devices against Side-Channel Analysis (SCA) attacks has been a major research effort. Even though many diffe...
A first-order chosen-plaintext DPA attack on the third round of DES
side-channel attack DPA countermeasure
2018/1/2
DPA attacks usually exhibit a "divide-and-conquer" property: the adversary needs to enumerate only a small space of the key (a key sub-space) when performing the DPA attack. This is achieved trivially...
Manifold Learning Towards Masking Implementations: A First Study
machine learning manifold learning dimensionality reduction
2017/11/21
Linear dimensionality reduction plays a very important role in side channel attacks, but it is helpless when meeting the non-linear leakage of masking implementations. Increasing the order of masking ...

2017/9/14
Hardware Trojans have gained high attention in academia, industry and by government agencies. The effective detection mechanisms and countermeasures against such malicious designs are only possible wh...
On the Easiness of Turning Higher-Order Leakages into First-Order
side-channel analysis masking higher-order
2017/3/31
Applying random and uniform masks to the processed intermediate values of cryptographic algorithms is arguably the most common countermeasure to thwart side-channel analysis attacks. So-called masking...
SHA-1 is a widely used 1995 NIST cryptographic hash function standard that was officially deprecated by NIST in 2011 due to fundamental security weaknesses demonstrated in various analyses and theoret...
