Abstract(in English) | OTU 2000 was proposed as a quantum cryptosystem which may not be broken even if quantum computers are constructed. In this paper, we focus on OTU 2000 and conduct numerical experiments based on the low-density attack and Low-Weight attacks against the restricted version (the field of rational numbers) and the imaginary quadratic field version of OTU 2000. As a result, we show which attack is more effective among utilized attacks and which version of OTU 2000 is weaker than the other under the lattice-based attack. |
