Communications device

Provided is a cryptographic technology which is capable of being used when encryption and decryption are performed in a single data processing device. 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.

Cryptographic technique for encrypting and decrypting on a single data processing device

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 (S) and transmits the solution to the server (S). When receiving the solution, the server generates a solution (S) and authenticates the client if the solution agrees with the solution received from the client (S). The server generates a new solution (S), encrypts a server certificate and an SSL certificate (S) by using the solution, and then transmits the certificates to the client (S). The client generates a new solution (S) and decrypts the server certificate and the SSL certificate by using the solution (S). The subsequent processing is identical to that of current SSL communications.

SSL communication system, client, server, SSL communication method, and computer program

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(S), and encrypted into encrypted authentication data (S). The encrypted authentication data are transmitted from the admission card to the security gate apparatus (S, S), and decrypted to be returned to the authentication data (S). 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 (S), and opens a gate plate when a determination result is positive (S).

A technique for preventing a man in the middle attack is proposed. 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(S), and encrypted into encrypted authentication data (S). The encrypted authentication data are transmitted from the admission card to the security gate apparatus (S, S), and decrypted to be returned to the authentication data (S). 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 (S), and opens a gate plate when a determination result is positive (S).

The present invention appropriately gives game media to a player without lowering a game playability. An information processing program according to the present invention realizes with a computer: a first draw function that determines first game media by performing a draw based on a first draw table on the basis of a predetermined game selection operation by a player; a second draw function that determines second game media by performing a draw based on a second draw table on the basis of the predetermined game selection operation by the player; a medium group creation function that creates a medium group including the first game media determined by the first draw function and the second game media determined by the second draw function; a game control function that runs, by using the medium group, the predetermined game on the basis of an operation by the player; and a management control function that determines that at least one of the first game media determined by the first draw function is managed in association with identification information of the player, and determines whether or not to manage at least one of the second game media determined by the second draw function in association with the identification information of the player on the basis of a game result of the predetermined game.

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 (S), and sent to the settlement device (S). The settlement device performs credit determination (S), generates temporary permission information if credit is possible (S), and sends the temporary permission information to the user terminal (S).
