How to Compare Profiled Side-Channel Attacks?
Side-channel attacks are an important class of attacks against cryptographic devices and profiled side-channel attacks are the most powerful type of side-channel attacks. In this scenario, an adversary first uses a device under his control in order to build a good leakage model. Then, he takes advantage of this leakage model to exploit the actual leakages of a similar target device and perform ...
متن کاملTowards Leakage Exploitation Optimality in Profiled Side-Channel Attacks
Template Attack is widely accepted to be one of the most powerful side-channel attacks, because it is usually assumed that one has a full knowledge of targeted crypto devices and thus be well capable of characterizing the side-channel leakages. However, the question of whether Template Attack is really optimal in terms of leakage exploitation rate is still unclear. In this paper, we present a n...
متن کاملDefend encryption systems against side- channel attacks
From its ancient origin as a tool for protecting sensitive wartime or espionage-related messages, cryptography has become a foundational building-block for securing the systems, protocols, and infrastructure that underpin our modern interconnected world. But the physical mechanisms used in performing encryption and decryption can leak information, making it possible to bypass this security. Pro...
متن کاملProvably Secure Countermeasures against Side-channel Attacks
Side-channel attacks exploit the fact that the implementations of cryptographic algorithms leak information about the secret key. In power analysis attacks, the observable leakage is the power consumption of the device, which is dependent on the processed data and the performed operations. Masking is a widely used countermeasure to thwart the powerful Differential Power Analysis (DPA) attacks. ...
