Title: Method for authenticating registered user employing quantum key

IPC: G06F21/34
Filed: 2002-07-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for authenticating registered users with high security capable of almost completely preventing illegitimate use.  <P>SOLUTION: When a registration user decides a password and stores the password to a quantum memory of an operation apparatus manager in a form of an orthogonal state quantum bit stream, the registration user sets a quantum key, the operation apparatus manager uses the quantum key to bring a password versus quantum bit stream into a non-orthogonal state and stores it to an authentication operating apparatus. When the registration user keys in the quantum key to the authentication operating apparatus to restore the password versus quantum bit stream to the orthogonal state at its use, the authentication operating apparatus collates the quantum bit stream with a quantum bit stream in a computer, and when they are coincident, the authentication operating apparatus performs a prescribed corresponding operation. Since the password versus quantum bit stream stored in the quantum key is in a non-orthogonal state, the probability of accurate forgery by a non-registered user is extremely low. When an erroneous falsified quantum key is keyed in the authentication operating apparatus, the stored password versus quantum bit stream is destroyed.  <P>COPYRIGHT: (C)2004,JPO
