Computational aspects of correlation power analysis

Joppe Willem Bos, Paul Bottinelli

Since the discovery of simple power attacks, the cryptographic research community has developed significantly more advanced attack methods. The idea behind most algorithms remains to perform a statistical analysis by correlating the power trace obtained wh ...

Hardware Attacks against Hash-based Cryptographic Algorithms

Aymeric Genet

This thesis surveys the current state of the art of hash-based cryptography with a view to finding vulnerabilities related to side-channel attacks and fault attacks. For side-channel investigation, we analyzed the power consumption of an Arduino Due microc ...

Clever Arbiters Versus Malicious Adversaries

Serge Vaudenay

When moving from known-input security to chosen-input security, some generic attacks sometimes become possible and must be discarded by a specific set of rules in the threat model. Similarly, common practices consist of fixing security systems, once an exp ...

Trustworthy Cloud Storage

Maxime Augier

The Cloud trend is an attempt to leverage economics of scale in the domain of computing resources. Unfortunately, this often means losing control of the lower levels of a computer system, and exposing users to new threat vectors. These threats may be signi ...

Instruction Set Extensions for Secure Applications

Paolo Ienne, Francesco Regazzoni

The main goal of this paper is to expose the community to past achievements and future possible uses of Instruction Set Extension (ISE) in security applications. Processor customization has proven to be an effective way for achieving high performance with ...

DES S-box generator

Serge Vaudenay, Lauren De Meyer

The Data Encryption Standard (DES) is a cryptographic algorithm, designed by IBM, that was selected to be the national standard in 1977 by the National Bureau of Standards. The algorithm itself was entirely published but the design criteria were kept secre ...

Dynamic NoC buffer allocation for MPSoC timing side channel attack protection

Mathias Soeken

Multi-Processors Systems-on-Chip (MPSoCs), as a key technology enabler of the new computation paradigm Internet-of-Things (IoT), are exposed to attacks. Malicious applications can be downloaded at runtime to the MPSoC, infect IPs and open doors to perform ...

Signature Schemes Secure Against Hard-to-Invert Leakage

Sebastian Faust

Side-channel attacks allow the adversary to gain partial knowledge of the secret key when cryptographic protocols are implemented in real-world hardware. The goal of leakage resilient cryptography is to design cryptosystems that withstand such attacks. In ...

Automatic Application of Power Analysis Countermeasures

Paolo Ienne, Francesco Regazzoni, Philip Brisk, David Novo Bruna, Ali Galip Bayrak

We introduce a compiler that automatically inserts software countermeasures to protect cryptographic algorithms against power-based side-channel attacks. The compiler first estimates which instruction instances leak the most information through side-channe ...
