QUANTUM AUTHENTICATION METHOD AND APPARATUS FOR A QSS(QUANTUM SECRET SHARING) PROTOCOL CAPABLE OF IDENTIFYING THE IDENTITIES OF USERS

摘要

PURPOSE: A quantum authentication method and apparatus for a QSS(Quantum Secret Sharing) protocol are provided to ensure efficiency by setting a short secret key regardless of the amount of quantum information and classical information transmitted from a protocol processing step.;CONSTITUTION: A quantum transmission unit transmits a quantum state through a quantum entangled transmission step(S200). A quantum authentication apparatus performs an error rate estimation step by using an error output unit(S300). The quantum authentication apparatus performs a user authentication step by using a user authentication unit(S400). The quantum authentication apparatus performs a secret key generating step by using a secret key administration unit(S500). The secret key administration unit performs a confidential sharing step(S600).;COPYRIGHT KIPO 2012
