Latest coverage for Side-Channel

Side-Channel Attacks are a class of cyber threats in information security where an attacker can glean sensitive information from the physical implementation of a system rather than exploiting software vulnerabilities. These attacks hinge on the observation of physical side effects that occur during the execution of a computer process, such as timing information, power consumption, electromagnetic leaks, or even sound to discern confidential data.

In the context of information security, side-channel attacks pose a significant risk because they can bypass traditional security measures and encryption. Consequently, they have become an area of great concern for security professionals, particularly when addressing the security of cryptographic systems and devices like smart cards, mobile devices, and IoT hardware where physical access is a realistic threat vector. Defending against side-channel attacks often involves implementing measures that obfuscate or minimize these emissions or otherwise increase the difficulty of accurate measurement for would-be attackers.
