Near Collision Side Channel Attacks
Side channel collision attacks are a powerful method to exploit side channel leakage. Otherwise than a few exceptions, collision attacks usually combine leakage from distinct points in time, making them inherently bivariate. This work introduces the notion of near collisions to exploit the fact that values depending on the same sub-key can have similar while not identical leakage. We show how s...
متن کاملClockwise Collision Analysis - Overlooked Side-Channel Leakage Inside Your Measurements
This paper presents a new side-channel attack technique called clockwise collision analysis. For the cryptographic implementations using synchronous digital circuit with a loop architecture, signal transitions as well as the side-channel leakage relates to not only the input data in the current cycle, but also the status in one-cycle before. The clockwise collision utilizes the fact that little...
متن کاملImproved Side-Channel Collision Attacks on AES
Side-channel collision attacks were proposed in [1] and applied to AES in [2]. These are based on detecting collisions in certain positions of the internal state after the first AES round for different executions of the algorithm. The attack needs about 40 measurements and 512 MB precomputed values as well as requires the chosen-plaintext possibility. In this paper we show how to mount a collis...
متن کاملAlgebraic Side-Channel Collision Attacks on AES
This paper presents a new powerful side-channel cryptanalytic method algebraic collision attacks representing an efficient class of power analysis being based on both the power consumption information leakage and specific structure of the attacked cryptographic algorithm. This can result in an extremely low measurement count needed for a key recovery. The algebraic collision attacks are well ap...
متن کاملStatistical Tools Flavor Side-Channel Collision Attacks
By examining the similarity of side-channel leakages, collision attacks evade the indispensable hypothetical leakage models of multi-query based side-channel distinguishers like correlation power analysis and mutual information analysis attacks. Most of the side-channel collision attacks compare two selective observations, what makes them similar to simple power analysis attacks. A multi-query ...
