Metamorphic IOTA [article]

Gewu Bu
2019 arXiv   pre-print
First, we propose a parameterized algorithm, E-IOTA, for tip selection which targets to reduce the number of random walks executed in previous versions (IOTA and G-IOTA) while maintaining the same security  ...  Interestingly, to the best of our knowledge this is the first formal analysis of the security guaranties of IOTA and its derivatives.  ...  This makes the TSA and the tangle unpredictable for attackers.  ...

How to Break IOTA Heart by Replaying?

Gerard De Roode, Ikram Ullah, Paul J. M. Havinga
2018 2018 IEEE Globecom Workshops (GC Wkshps)  
Attack methodology and proof of concept for the replay attack is presented. Our proposed exploitation methodology is based upon address reuse, while IOTA in default mode does not reuse addresses.  ...  Distrust, and privation of balance can be some of the severe impacts of this vulnerability. Index Terms-IOTA, Blockchain, cryptocurrency, security exploitation, and replay attack.  ...  As mentioned earlier, IoT has overwhelming applications in logistics that can enhance efficiency and quality of service for the transport and logistics industry.  ...

Computing Resource Allocation Scheme for DAG-Based IOTA Nodes

Houssein Hellani, Layth Sliman, Abed Ellatif Samhat, Ernesto Exposito
2021 Sensors  
In this paper, we introduce an efficient mechanism to distribute the tasks fairly among full nodes and hence achieve load balancing.  ...  The light nodes are nodes with low computing resources which seek full nodes' help to validate and attach its transaction to the Tangle.  ...  Conflicts of Interest: The authors declare no conflicts of interest.  ...
