Higher-Order Threshold Implementations [PDF]

, 2014
Higher-order differential power analysis attacks are a serious threat for cryptographic hardware implementations. In particular, glitches in the circuit make it hard to protect the implementation with masking. The existing higher-order masking countermeasures that guarantee security in the presence of glitches use multi-party computation techniques and

Combined Threshold Implementation

Transactions on Cryptographic Hardware and Embedded Systems
Physical security is an important aspect of devices for which an adversary can manipulate the physical execution environment. Recently, more and more attention has been directed towards a security model that combines the capabilities of passive and ...

A More Efficient AES Threshold Implementation [PDF]

, 2014
Threshold Implementations provide provable security against first-order power analysis attacks for hardware and software implementations. Like masking, the approach relies on secret sharing but it differs in the implementation of logic functions. At Eurocrypt 2011 Moradi et al.

Lattice-Based Threshold Signature Implementation for Constrained Devices

Proceedings of the 20th International Conference on Security and Cryptography, 2023
Threshold signatures have gained increased attention especially due to their recent applications in blockchain technologies. In fact, current cryptocurrencies such as Bitcoin, and Cardano started to support multi-signature transactions. Even if the Schnorr-based threshold signatures improve the blockchain’s privacy and scalability, these schemes do not

Threshold effects in cointegrating relationships [PDF]

, 2006
In this paper, we introduce threshold-type nonlinearities within a single-equation cointegrating regression model and propose a testing procedure for testing the null hypothesis of linear cointegration vs. cointegration with threshold effects.

A mixed distribution to fix the threshold for Peak-Over-Threshold wave height estimation [PDF]

, 2022
Modelling extreme values distributions, such as wave height time series where the higher waves are much less frequent than the lower ones, has been tackled from the point of view of the Peak-Over-Threshold (POT) methodologies, where modelling is based on

LLTI: Low-Latency Threshold Implementations

IEEE Transactions on Information Forensics and Security, 2021
With the enormous increase in portable cryptographic devices, physical attacks are becoming similarly popular. One of the most common physical attacks is Side-Channel Analysis (SCA), extremely dangerous due to its non-invasive nature. Threshold Implementations (TI) was proposed as the first countermeasure to provide provable security in masked hardware

AN OPTIONAL THRESHOLD WITH SVM CLOUD DETECTION ALGORITHM AND DSP IMPLEMENTATION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
This paper presents a method which combines the traditional threshold method and SVM method, to detect the cloud of Landsat-8 images. The proposed method is implemented using DSP for real-time cloud detection.

Threshold Implementations in the Robust Probing Model [PDF]

Proceedings of ACM Workshop on Theory of Implementation Security Workshop, 2019
Threshold Implementations (TI) are provably secure algorithmic countermeasures against side-channel attacks in the form of differential power analysis. The strength of TI lies in its minimal algorithmic requirements. These requirements have been studied over more than 10 years and many efficient implementations for symmetric primitives have been ...
