QUANTUM SIGNATURE METHOD AND QUANTUM SECRET SHARING METHOD USING QUANTUM TRAPDOOR ONE-WAY FUNCTION

摘要

This specification discloses a quantum public-key cryptosystem. The quantum public-key cryptosystem may use two rotation operators R_{{circumflex over (n)}}(θ) and R_{{circumflex over (m)}}(φ) satisfying a cyclic evolution. The two rotation operators R_{{circumflex over (n)}}(θ) and R_{{circumflex over (m)}}(φ) do not have a commutation relation or an anti-commutation relation with each other. The commutation relation or the anti-commutation relation is established when either of the following conditions is satisfied: θ=2iπ, φ=2jπ, or {circumflex over (n)}·{circumflex over (m)}=1 (i, j=integer), and θ=(2k+1)π, φ=(2l+1)π, or {circumflex over (n)}·{circumflex over (m)}=0 (k, l=integer).
