A Survey of Side-Channel Attack and Security Assessment for Cryptographic Equipment

Abstract

In order to understand the development of current channel energy analysis technology and protection strategy, at the same time, we will lay the foundation for establishing safety evaluation system about Encryption device in the next stage. We analyzed the side-channel attacks of the current mainstream encryption algorithms. The side-channel attack is classified by combining the specific operations of the algorithm that are easily attacked by the attacker. Aiming at the more popular DPA attacks, the paper focuses on the corresponding protection strategies, including the first-order DPA attack defense strategy and the second-order DPA attack defense strategy. Finally, the evaluation index of the current safety assessment system is summarized, and the effect of each index is elaborated.

A Randomized Switched-Mode Voltage Regulation System for IoT Edge Devices to Defend Against Power Analysis based Side Channel Attacks

“…Side channel attacks (SCA) have been introduced to attack encryption algorithms and steal the security keys by analyzing the energy or frequency fluctuations on embedded devices [13], [23]. SCA is based on encryption algorithms that can be roughly divided into two categories: common key system based and public key based [2]. Some existing methods that are used to mitigate power analysis based SCA use (a) a capacitor in parallel to the target device, (b) an inductor in series with the target device, (c) LC filter, (d) Zener diode, and (e) another target device in parallel [10].…”

Robust security framework with bit‐flipping attack and timing attack for key derivation functions

“…Although KDFs have been proven to be secure by using the mathematical analysis [7], KDFs could be susceptible to physical attacks during implementation. These types of attacks are known as side‐channel attacks [9, 10]. Side‐channel attacks exploit information leakage during cryptographic implementations such as execution time [11–13], electromagnetic radiation [14, 15], acoustic [16, 17], and power consumption [18, 19] to infer sensitive information.…”
