Quantum computers pose a risk for today’s IT infrastructure. Common elliptic curves are broken with a computing power of 1,500 qubits. Widely used algorithms like RSA-1024 are broken with about 2,048 qubits. Current Quantum Computer use up to 72 qubit (Google) and scalability is still a major issue....
In this article, we present a cryptographic flaw in the Zerocoin cryptographic scheme (not Zerocash), which allows an attacker to burn coins of honest users. On the way, we identified two more critical coding issues in a software library implementing Zerocoin, allowing an attacker to create mone...
