Fair and Decentralized Exchange of Digital Goods
Ariel Futoransky, Carlos Sarraute, Daniel Fernandez +2
We construct a privacy-preserving, distributed and decentralized marketplace where parties can exchange data for tokens. In this market, buyers and sellers make transactions in a b…
WibsonTree: Efficiently Preserving Seller's Privacy in a Decentralized Data Marketplace
Ariel Futoransky, Carlos Sarraute, Ariel Waissbein +2
We present a cryptographic primitive called WibsonTree designed to preserve users' privacy by allowing them to demonstrate predicates on their personal attributes, without revealin…
BatPay: a gas efficient protocol for the recurrent micropayment of ERC20 tokens
Hartwig Mayer, Ismael Bejarano, Daniel Fernandez +5
BatPay is a proxy scaling solution for the transfer of ERC20 tokens. It is suitable for micropayments in one-to-many and few-to-many scenarios, including digital markets and the di…
Wibson Protocol for Secure Data Exchange and Batch Payments
Daniel Fernandez, Ariel Futoransky, Gustavo Ajzenman +2
Wibson is a blockchain-based, decentralized data marketplace that provides individuals a way to securely and anonymously sell information in a trusted environment. The combination…
Secure Exchange of Digital Goods in a Decentralized Data Marketplace
Ariel Futoransky, Carlos Sarraute, Ariel Waissbein +3
We are tackling the problem of trading real-world private information using only cryptographic protocols and a public blockchain to guarantee honest transactions. In this project,…
An Oblivious Password Cracking Server
Aureliano Calvo, Ariel Futoransky, Carlos Sarraute
Building a password cracking server that preserves the privacy of the queries made to the server is a problem that has not yet been solved. Such a server could acquire practical re…
Attack Planning in the Real World
Jorge Lucangeli Obes, Carlos Sarraute, Gerardo Richarte
Assessing network security is a complex and difficult task. Attack graphs have been proposed as a tool to help network administrators understand the potential weaknesses of their n…
An Algorithm to Find Optimal Attack Paths in Nondeterministic Scenarios
Carlos Sarraute, Gerardo Richarte, Jorge Lucangeli Obes
As penetration testing frameworks have evolved and have become more complex, the problem of controlling automatically the pentesting tool has become an important question. This can…
An attack on MySQL's login protocol
Ivan Arce, Emiliano Kargieman, Gerardo Richarte +2
The MySQL challenge-and-response authentication protocol is proved insecure. We show how can an eavesdropper impersonate a valid user after witnessing only a few executions of this…
Simulation of Computer Network Attacks
Carlos Sarraute, Fernando Miranda, Jose I. Orlicki
In this work we present a prototype for simulating computer network attacks. Our objective is to simulate large networks (thousands of hosts, with applications and vulnerabilities)…
Advanced Software Protection Now
Diego Bendersky, Ariel Futoransky, Luciano Notarfrancesco +2
Software digital rights management is a pressing need for the software development industry which remains, as no practical solutions have been acclamaimed succesful by the industry…
Simulating Cyber-Attacks for Fun and Profit
Ariel Futoransky, Fernando Miranda, Jose Orlicki +1
We introduce a new simulation platform called Insight, created to design and simulate cyber-attacks against large arbitrary target scenarios. Insight has surprisingly low hardware…
Using Neural Networks to improve classical Operating System Fingerprinting techniques
Carlos Sarraute, Javier Burroni
We present remote Operating System detection as an inference problem: given a set of observations (the target host responses to a set of tests), we want to infer the OS type which…
Building Computer Network Attacks
Ariel Futoransky, Luciano Notarfrancesco, Gerardo Richarte +1
In this work we start walking the path to a new perspective for viewing cyberwarfare scenarios, by introducing conceptual tools (a formal model) to evaluate the costs of an attack,…
