In the world of integrated circuits (ICs), ensuring the security and integrity of the design is one of the greatest challenges. In an environment where hardware Trojans—malicious modifications inserted into the hardware—can be added either intentionally or accidentally, understanding how to detect these threats is essential to ensuring system reliability. In this article, we explore […]
The security of electronic systems is becoming increasingly relevant, especially with the advancement of technologies and the growing complexity of integrated circuits. One of the emerging threats in this scenario is the hardware Trojan – a malicious insertion during the chip manufacturing process that can compromise the functionality, confidentiality, and integrity of devices. In this
Hardware security is becoming increasingly relevant in today’s technological landscape. With the growing complexity of systems and the integration of circuits into critical devices, understanding and mitigating threats like hardware Trojans is essential to ensure the integrity and reliability of our equipment. In this article, we explore two key concepts: hardware Trojans and trusted integrated
Modular exponentiation is a fundamental tool in many cryptographic applications, but its classic algorithms—such as the “square and multiply” method—have vulnerabilities that can be exploited through side-channel attacks. Fortunately, there is an innovative approach that enhances the security of these processes: Randomized Modular Exponentiation. In this article, we will explore this technique by understanding how
The security of cryptographic systems is an ever-evolving subject, and the methods used to attack them are continuously improving. Among the various types of side channel attacks, timing attacks and scan chain attacks stand out as particularly sophisticated threats. In this article, we explore how these attacks work using the RSA algorithm as an example,
The security of cryptographic systems goes far beyond mathematical algorithms. Often, what appears to be a simple computational operation inadvertently reveals valuable information through its power consumption. In this article, we explore power analysis attacks, examining both the simple (SPA) and differential (DPA) methods. Get ready to journey behind the scenes of cryptographic devices and
In an increasingly connected world, protecting sensitive data isn’t just best practice—it’s essential. Cryptographic algorithms like RSA and AES are mathematically secure, but their real‑world implementations can leak secret information through side channels. In this article, we’ll dive into how a processor’s memory hierarchy—especially cache memory—can betray secrets, and what you can do to defend
