Detecting Faults in Inner Product Masking Scheme - IPM-FD: IPM with Fault Detection
Side-channel Analysis Inner Product Masking Fault Detection
<
2019/8/14
Side-channel analysis and fault injection attacks are two typical threats to cryptographic implementations, especially in modern embedded devices. Thus there is an insistent demand for dual side-chann...
Privacy-Preserving Classification of Personal Text Messages with Secure Multi-Party Computation: An Application to Hate-Speech Detection

<
2019/6/26
Classification of personal text messages has many useful applications in surveillance, e-commerce, and mental health care, to name a few. Giving applications access to personal texts can easily lead t...
A Cautionary Note Regarding the Usage of Leakage Detection Tests in Security Evaluation
side-channel analysis leakage detection security certification
<
2019/6/14
An established ingredient in the security evaluation of cryptographic devices is leakage detection, whereby physically observable characteristics such as the power consumption are measured during oper...
Secure multiparty PageRank algorithm for collaborative fraud detection

<
2018/11/8
Collaboration between financial institutions helps to improve detection of fraud. However, exchange of relevant data between these institutions is often not possible due to privacy constraints and dat...
Towards Lightweight Cryptographic Primitives with Built-in Fault-Detection

<
2018/8/10
We introduce a novel approach for designing symmetric ciphers to resist fault injection. The approach is fairly generic and applies to round functions of block ciphers, cryptographic permutations and ...
Non-Malleable Codes for Partial Functions with Manipulation Detection

<
2018/6/5
Non-malleable codes were introduced by Dziembowski, Pietrzak and Wichs (ICS '10) and its main application is the protection of cryptographic devices against tampering attacks on memory. In this work, ...
Leakage-resilient Algebraic Manipulation Detection Codes with Optimal Parameters
Leakage-resilient AMD Algebraic Manipulation Detection Leakage resilient codes
<
2018/1/17
Algebraic Manipulation Detection (AMD) codes [CDF+08] are keyless message authentication codes that protect messages against additive tampering by the adversary assuming that the adversary cannot “see...
Detection of cryptographic algorithms with grap

<
2017/11/27
The disassembled code of an executable program can be seen as a graph representing the possible sequence of instructions (Control Flow Graph). grap is a YARA-like tool, completely open-source, and abl...
Early Detection and Analysis of Leakage Abuse Vulnerabilities
cryptanalysis efficiently searchable encryption encrypted databases
<
2017/11/1
In order to be useful in the real world, efficient cryptographic constructions often reveal, or ``leak,'' more information about their plaintext than one might desire. Up until now, the approach for a...
An attacker or evaluator can detect more information leakages if he improves the Signal-to-Noise Ratio (SNR) of power traces in his tests. For this purpose, pre-processings such as de-noise, distribut...
HAL- The Missing Piece of the Puzzle for Hardware Reverse Engineering, Trojan Detection and Insertion

<
2017/8/21
Hardware manipulations pose a serious threat to numerous systems, ranging from myriads of smart-X devices to military systems. In many attack scenarios an adversary merely has access to the low-level,...
Towards Sound and Optimal Leakage Detection Procedure
Side channel analysis leakage detection higher criticism
<
2017/4/5
Evaluation of side channel leakage for the embedded crypto systems requires sound leakage detection procedures. We relate the test vector leakage assessment (TVLA) procedure to the statistical minimum...
Cache-Base Application Detection in the Cloud Using Machine Learning
