Enhancing Collision Attacks [PDF]

open access: yes, 2004
Side Channel Attacks (SCA) have received a huge interest in the last 5 years. These new methods consider non-cryptographic sources of information (like timing or power consumption) in addition to traditional techniques. Consequently block ciphers must now resist a variety of SCAs, among which figures the class of “collision attacks”.

A Collision-Attack on AES [PDF]

open access: yes, 2004
Recently a new class of collision attacks which was originally suggested by Hans Dobbertin has been introduced. These attacks use side channel analysis to detect internal collisions and are generally not restricted to a particular cryptographic algorithm. As an example, a collision attack against DES was proposed which combines internal collisions with

Investigating the Avalanche Effect of Various Cryptographically Secure Hash Functions and Hash-Based Applications

open access: yesIEEE Access, 2022
In modern cryptography, hash functions are considered as one of the key components for secure communication. They play a vital role in a wide range of applications such as ensuring the authentication and integrity of the data, in forensic investigation ...

Instruction-Fetching Attack and Practice in Collision Fault Attack on AES

open access: yesSymmetry, 2022
A Fault Attack (FA) is performed mainly under the data corruption model and poses a threat to security chips. Instruction corruption can enact the same purpose at the behavioral level, which is produced by interfering with the instruction system. Laser Fault Injection (LFI) on program memory during the instruction-fetching process, which we refer to as

Hypothesis Testing Based Side-Channel Collision Analysis

open access: yesIEEE Access, 2019
Side-channel collision analysis has become a research hotspot since its first publication in 2003. Compared with differential power analysis (DPA) and correlation power analysis (CPA), collision analysis does not need to know the intermediate value and ...

Two Improved Multiple‐Differential Collision Attacks [PDF]

open access: yesMathematical Problems in Engineering, 2014
In CHES 2008, Bogdanov proposed multiple‐differential collision attacks which could be applied to the power analysis attacks on practical cryptographic systems. However, due to the effect of countermeasures on FPGA, there are some difficulties during the collision detection, such as local high noise and the lack of sampling points.

An Efficient Collision Power Attack on AES Encryption in Edge Computing

open access: yesIEEE Access, 2019
Edge computing has become a promising paradigm for the context-aware and delay-sensitive IoT data analytics. For the sake of security, some cryptographic algorithms such as AES, RSA, and so on, are employed for the encryption communication and ...

Improved preimage and pseudo-collision attacks on SM3 hash function

open access: yesTongxin xuebao, 2018
A preimage attack on 32-step SM3 hash function and a pseudo-collision attack on 33-step SM3 hash function respectively were shown.32-step preimage attack was based on the differential meet-in-the-middle and biclique technique,while the previously known ...

IDCAIS: Inter-Defender Collision-Aware Interception Strategy against Multiple Attackers [PDF]

open access: yesarXiv, 2021
In the prior literature on multi-agent area defense games, the assignments of the defenders to the attackers are done based on a cost metric associated only with the interception of the attackers. In contrast to that, this paper presents an Inter-Defender Collision-Aware Interception Strategy (IDCAIS) for defenders to intercept attackers in order to ...

Preimage and pseudo collision attacks on round-reduced DHA-256 hash function

open access: yesTongxin xuebao, 2013
A preimage attack on DHA-256 hash function reduced to 37-round and a pseudo collision attack on the func-tion reduced to 39-round were proposed respectively.Based on the meet-in-the-middle attack,the Biclique technique was used to improve the preimage ...
