An Efficient Collision Power Attack on AES Encryption in Edge Computing
IEEE 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 ...

Adaptive Chosen-Plaintext Collision Attack on Masked AES in Edge Computing
IEEE Access, 2019 Edge computing handles delay-sensitive data and provides real-time feedback, while it brings data security issues to edge devices (such as IoT devices and edge servers). Side-channel attacks main threaten to these devices.

A Symbolic Intruder Model for Hash-Collision Attacks [PDF]
, 2006 In the recent years, several practical methods have been published to compute collisions on some commonly used hash functions. In this paper we present a method to take into account, at the symbolic level, that an intruder actively attacking a protocol ...

Preimage and collision attacks on reduced Ascon using algebraic strategies [PDF]
CybersecurityAscon, a family of algorithms that supports hashing and authenticated encryption, is the winner of the NIST Lightweight Cryptography Project. In this paper, we propose an improved preimage attack against 2-round Ascon-XOF-64 with a complexity of $$2^{33}$

Optimizing Fast Near Collision Attack on Grain Using Linear Programming [PDF]
IEEE Access, 2019 In 2018, an attack named fast-near-collision attack (FNCA) was proposed, which is an improved version of near-collision attack (NCA) on Grain-v1, one of the three hardware-oriented finalists of the eSTREAM project.

Understanding realistic attacks on airborne collision avoidance systems [PDF]
Journal of Transportation Security, 2022 AbstractAirborne collision avoidance systems provide an onboard safety net should normal air traffic control procedures fail to keep aircraft separated. These systems are widely deployed and have been constantly refined over the past three decades, usually in response to near misses or mid-air collisions.

Collision Attack on Boole [PDF]
, 2009 Boole is a hash function designed by Gregory Rose and was submitted to the NIST Hash competition. It is a stream cipher based hash function which produces digests up to 512 bits. Different variants exist, namely Boole16, Boole32 and Boole64 where the number refers to word size in bits. Boole64 is considered as the official submission.

Collision Attack on 5 Rounds of Grøstl [PDF]
Fast Software Encryption Workshop, 2015 In this article, we describe a novel collision attack for up to 5 rounds of the Grostl hash function. This significantly improves upon the best previously published results on 3 rounds. By using a new type of differential trail spanning over more than one message block we are able to construct collisions for Grostl-256 on 4 and 5 rounds with complexity
