Repeater Attacks in Quantum Entanglement Networks
Abstract
Quantum entanglement networks represent cutting-edge technologies with critical applications in secure communication. However, their reliance on the unconditional trust of quantum repeaters introduces potential vulnerabilities to third-party attacks. Notably, the Quantum Hijacking Attack and the Quantum Black Hole Attack have gained attention for exploiting this trust-based weakness. This study analyzes the mechanisms behind these attacks, with particular emphasis on the Quantum Black Hole Attack, and highlights the limitations of current tomography-based detection methods in effectively identifying such threats.
