Analysis of IOTA Tangle Stability in High Transaction Rates

Habibullah Yajam; Mohammad Ali Akhaee

Volume 15, Issue 2 , July 2023, Pages 152-162


  The future of the IoT requires new methods of payment that can handle millions of transactions per second. IOTA cryptocurrency aims at providing such a solution. It uses a consensus algorithm based on directed acyclic graphs (DAG) that is called Tangle. A tip selection algorithm (TSA) is a part of Tangle ...  Read More

MISC: Multi-Input Secure Two-Party Computation

Farhad Taheri Ardakani; Siavash Bayat Sarmadi

Volume 15, Issue 2 , July 2023, Pages 163-177


  Secure multi-party computation (MPC) allows a group of parties to compute a function on their private inputs securely. Classic MPC protocols for two parties use either Yao's garbled circuit (GC) or the Goldreich-Micali-Wigderson (GMW) protocol. In this paper, we propose MISC, a multi-input secure computation ...  Read More

A Fragile Watermarking by Hamming Code on Distributed Pixels with Perfect Recovery for Small Tampers

Faeze Rasouli; Mohammad Taheri; Reza Rohani Sarvestani

Volume 15, Issue 2 , July 2023, Pages 230-239


  Fragile watermarking is the task of embedding a watermark in a media (an image in this paper) such that even small changes, called tamper, can be detected or even recovered to prevent unauthorized alteration. A well-known category of spatial fragile watermarking methods is based on embedding the watermark ...  Read More

An Auto-Encoder based Membership Inference Attack against Generative Adversarial Network

Maryam Azadmanesh; Behrouz Shahgholi Ghahfarokhi; Maede Ashouri-Talouki

Volume 15, Issue 2 , July 2023, Pages 240-253


  Using generative models to produce unlimited synthetic samples is a popular replacement for database sharing. Generative Adversarial Network (GAN) is a popular class of generative models which generates synthetic data samples very similar to real training datasets. However, GAN models do not necessarily ...  Read More

Oblivious Transfer Using Generalized Jacobian of Elliptic Curves

Maryam Rezaei Kashi; Mojtaba Bahramian

Volume 15, Issue 2 , July 2023, Pages 260-273


  ‎Oblivious transfer is one of the important tools in cryptography‎, ‎in which a sender sends a message to a receiver with a probability between 0 and 1‎, ‎while the sender remains oblivious that the receiver has received the message‎.‎A flavor of $OT$ schemes is chosen $t$-out-of-$k$ ...  Read More
