Impact of Aging on Template Attacks

Proceedings of the 2018 Great Lakes Symposium on VLSI, 2018
Template attack is the most powerful side-channel attack from an information theoretic point of view. This attack is launched in two phases. In the first phase (training) the attacker uses a training device to estimate leakage models for targeted intermediate computations, which are then exploited in the second phase (matching) to extract secret ...

Construction of Overflow Attacks Based on Attack Element and Attack Template

2011 Seventh International Conference on Computational Intelligence and Security, 2011
According to the requirements of effective, credible and controllable for Attack Resistant Test, a standard structure of overflow attacks, and a new method to realize the overflow attacks were built in the paper. By analyzing the characteristics of the process to realize overflow attacks, we extract the attack elements of overflow attacks. Based on the

A Deep Learning-Assisted Template Attack Against Dynamic Frequency Scaling Countermeasures [PDF]

IEEE Transactions on Computers
In the last decades, machine learning techniques have been extensively used in place of classical template attacks to implement profiled side-channel analysis. This manuscript focuses on the application of machine learning to counteract Dynamic Frequency

Practical Template Attacks

2005
Side-channel attacks pose a serious threat to implementations of cryptographic algorithms. In the pioneering article of Chari, Rao and Rohatgi, the general idea behind template attacks was introduced. Template attacks apply advanced statistical methods and can break implementations secure against other forms of side-channel attacks.

Template Attacks on ECDSA

2009
Template attacks have been considered exclusively in the context of implementations of symmetric cryptographic algorithms on 8-bit devices. Within these scenarios, they have proven to be the most powerful attacks. In this article we investigate how template attacks can be applied to implementations of an asymmetric cryptographic algorithm on a 32-bit ...

Template Attack with Coalescence Principle

2021
On the one hand, template attacks have been introduced to deal with multivariate leakages, with as few assumptions as possible on the leakage model. On the other hand, many works have underlined the need for dimensionality reduction. In this chapter, we clarify the relationship between template attacks in full space and in linear subspaces.

Composable Template Attacks Using Templates for Individual Architectural Components

2018 IEEE 36th International Conference on Computer Design (ICCD), 2018
With embedded systems and IoT devices being widely deployed nowadays, their security becomes a major concern. Among all possible attacks, side channel attacks (SCA) represent a major source of threats. For power side channels, template attacks have been proven to be efficient and widely applicable.

Template Attacks with Partial Profiles and Dirichlet Priors

Proceedings of the Hardware and Architectural Support for Security and Privacy 2016, 2016
In order to retrieve the secret key in a side-channel attack, the attacker computes distinguisher values using all the available data. A profiling stage is very useful to provide some a priori information about the leakage model. However, profiling is essentially empirical and may not be exhaustive.

Template Attacks on Masking—Resistance Is Futile

2006
In this article we discuss different types of template attacks on masked implementations. All template attacks that we describe are applied in practice to a masked AES software implementation on an 8-bit microcontroller. They all break this implementation. However, they all require quite a different number of traces.

Template Attack Based Deobfuscation of Integrated Circuits

2017 IEEE International Conference on Computer Design (ICCD), 2017
Logic encryption algorithms have gained wide popularity to safeguard Integrated Circuits (ICs) from being pirated or counterfeited in untrusted third-party foundries. However, an untrusted foundry can reverse engineer the netlist and gain important insight regarding the design of a chip.
