  • Publication number: 20230418924
    Abstract: A security gate system includes an admission card and a security gate apparatus. The admission card has condition data that is data for specifying a condition to be satisfied when or before or after encrypted authentication data are transferred from the admission card to the security gate apparatus. When a user attempts to enter a building, authentication data including condition data are generated in the admission card 100 (S802), and encrypted into encrypted authentication data (S803). The encrypted authentication data are transmitted from the admission card to the security gate apparatus (S804, S904), and decrypted to be returned to the authentication data (S905). The security gate apparatus performs authentication determination which is a determination as to whether a condition specified by the condition data included in the authentication data is satisfied (S906), and opens a gate plate when a determination result is positive (S907).

  • Patent number: 11631079
    Abstract: A settlement system with higher security which replaces a settlement system using credit cards is provided. The settlement system has a user terminal, a settlement device, and a settlement terminal. First, a user ID, a password, and amount information identifying an amount are inputted in the settlement system (S912), and sent to the settlement device (S913). The settlement device performs credit determination (S922), generates temporary permission information if credit is possible (S923), and sends the temporary permission information to the user terminal (S924). The user terminal generates a one-time password (S915). The one-time password is inputted to the settlement terminal (S931). If the one-time password sent from the settlement terminal to the settlement device is identical to the one-time password created in the settlement device (S926), the settlement device allows a user's payment (S927).

  • Publication number: 20230050675
    Abstract: Provided is a highly practical cryptographic technology which is capable of being used when encryption and decryption are performed in a single data processing device and which can be said to be unbreakable, or close to unbreakable. A data processing device is configured to generate encrypted data by encrypting processing target data and record the generated encrypted data in a predetermined recording medium, and to decrypt the encrypted data recorded in the recording medium back into the processing target data. The processing target data is data of a text. Encryption is performed in units of plaintext split data generated by splitting the processing target data into pieces having a predetermined number of bits. The units of the splitting are equal to or shorter than a bit length of a code for identifying characters in the text.

  • Patent number: 11521192
    Abstract: A settlement system with higher security which replaces a settlement system using credit cards is provided. The settlement system has a user terminal, a settlement device, and a settlement terminal. First, a user ID, a password, and upper limit amount information identifying an amount are inputted in a user terminal 100 (S912), and sent to the settlement device (S913). The settlement device performs credit determination (S922), generates temporary permission information if credit is possible (S923), and sends the temporary permission information to the user terminal (S924). The user terminal generates a one-time password (S915). The one-time password is inputted to the settlement terminal (S931). If the one-time password sent from the settlement terminal to the settlement device is identical to the one-time password created in the settlement device, the settlement device allows a user's payment (S928).

  • Patent number: 11394545
    Abstract: The present invention provides a secure technique that allows two communication apparatus that perform encrypted communication to have a common initial solution. A large number of user apparatuses all have a function of generating the same solution under the same condition as far as the user apparatuses have the same initial solution, and can perform encrypted communication using solutions successively generated in synchronization from the same initial solution. All the user apparatuses and a server share the same initial solution and have a function of generating the same solution under the same condition and thus can generate synchronized solutions. The server generates synchronization information, which is information required to generate the initial solution but is not the initial solution itself (S2002), and transmits the synchronization information to at least one of two user apparatuses performing encrypted communication (S2003).

  • Publication number: 20220029819
    Abstract: SSL is improved with stronger defense against an attack from a third party, in particular, an MITMA. A client and a server each have the function of generating the same solution under the same conditions. The client generates a first solution (S1002) and transmits the solution to the server (S1003). When receiving the solution, the server generates a solution (S2002) and authenticates the client if the solution agrees with the solution received from the client (S2003). The server generates a new solution (S2004), encrypts a server certificate and an SSL certificate (S2005) by using the solution, and then transmits the certificates to the client (S2006). The client generates a new solution (S1005) and decrypts the server certificate and the SSL certificate by using the solution (S1006). The subsequent processing is identical to that of current SSL communications.
