Title: System for preventing alteration in electronic authentication
Inventor: ISHIZUKA KOICHI
IPC: G06F21/35
Filed: 2019-09-13
Abstract: To provide a safer encryption communication environment in an alteration prevention system that divides a secret key into a plurality of restorable dispersion values.SOLUTION: A system 1 includes: a user terminal for accessing electronic information or a control object terminal to which access is restricted; an information provision body that can provide electronic information for a user terminal and can be electrically separated; and a preliminary information provision body. The user terminal, the information provision body, and the preliminary information provision body individually store dispersion values differing from one another that are required for restoring a secret key required for electronic authentication at the time of accessing the electronic information or the control object terminal. The user terminal restores the secret key by combining a dispersion value stored by the user terminal with a dispersion value provided from the information provision body and/or the preliminary information provision body. When a dispersion value is provided from the preliminary information provision body at the time of restoring the secret key, the user terminal sets a reception prohibition state in which provision of a dispersion value from the information provision body for which the preliminary information provision body is substituted is not received after the next restoration.SELECTED DRAWING: Figure 1
