Patent application number | Description | Published |
20090028341 | COMMUNICATION SYSTEM, COMMUNICATION DEVICE AND PROCESSING METHOD THEREFOR - A master generates a session key, receives public keys from a plurality of slaves, encrypts the session key using the individual public keys, transmits the encrypted session key to the plurality of slaves, encrypts data using the encrypted session key, and sends it to the plurality of slaves. A plurality of slaves transmit public keys to a master device, receive and decrypt a session key encrypted using individual public keys, receive data encrypted using the session key from the master, and decrypt it using the decrypted session key. | 01-29-2009 |
20100027414 | COMMUNICATION APPARATUS, IMAGE INPUT APPARATUS, IMAGE OUTPUT APPARATUS, WIRELESS COMMUNICATION CIRCUIT, METHOD FOR CONTROLLING COMMUNICATION APPARATUS, AND PROGRAM - After connection to another communication apparatus using the first communication-parameter set fails, and thereafter, connection to the other communication apparatus using the second communication-parameter set is successfully established, the connection to the other communication apparatus using the first communication-parameter set is attempted again. | 02-04-2010 |
20100299730 | USER AUTHENTICATION METHOD, WIRELESS COMMUNICATION APPARATUS, BASE STATION, AND ACCOUNT MANAGEMENT APPARATUS - A wireless communication apparatus transmits a user identifier to an account management apparatus through a communication apparatus. The account management apparatus generates code generation information, and generates code information using authentication information that corresponds to the user identifier and the code generation information. The account management apparatus transmits the code information and the code generation information to the communication apparatus. The communication apparatus sets code information, and transmits the code generation information to the wireless communication apparatus. The wireless communication apparatus generates code information using the code generation information and the authentication information, and when wireless network parameters are set, notifies the account management apparatus of success of authentication. The account management apparatus performs a process to permit the wireless communication apparatus to connect to a communication network. | 11-25-2010 |
20100332666 | COMMUNICATION APPARATUS PERFORMING COMMUNICATION PARAMETER CONFIGURATION PROCESS AND METHOD FOR CONTROLLING THE SAME - The present invention solves a problem that can occur when operation for performing a communication parameter configuration process is started on three or more communication apparatuses. For that purpose, when a communication apparatus that is performing a communication parameter configuration process with a first communication apparatus receives a start request to start a communication parameter configuration process from a second communication apparatus, the communication apparatus sends, to the second communication apparatus, network information in which the communication apparatus participates after the end of the communication parameter configuration process with the first communication apparatus. | 12-30-2010 |
20120113970 | COMMUNICATION APPARATUS AND METHOD OF CONTROLLING SAME - In a communication apparatus capable of communicating concurrently with a first network and with a second network different from the first network, the address of another communication apparatus in the second network is detected, whether the detected address is in use in the first network is confirmed and, when data is transmitted to the detected address in a case where it is confirmed that the detected address is in use, stores the fact that data will be transmitted to the second network. | 05-10-2012 |
20120144199 | COMMUNICATION APPARATUS, CONTROL METHOD FOR COMMUNICATION APPARATUS, AND PROGRAM - A communication apparatus of the present invention is a communication apparatus that communicates with a plurality of other communication apparatuses, and starts processing for setting an address for the communication apparatus using encrypted communication when encrypted communication with the plurality of communication apparatuses becomes possible by sharing encryption keys for encrypting communication with the other communication apparatuses. | 06-07-2012 |
20120233338 | COMMUNICATION APPARATUS, METHOD FOR CONTROLLING THE COMMUNICATION APPARATUS, AND STORAGE MEDIUM - A communication apparatus comprises: a detection unit configured to detect a communicable network; a determination unit configured, if a plurality of networks are detected by the detection unit, to determine a base station constructing the detected networks; and a connection unit configured to perform connection processing in accordance with the result of determination by the determination unit. | 09-13-2012 |
20130243196 | COMMUNICATION SYSTEM, COMMUNICATION DEVICE AND PROCESSING METHOD THEREFOR - A master generates a session key, receives public keys from a plurality of slaves, encrypts the session key using the individual public keys, transmits the encrypted session key to the plurality of slaves, encrypts data using the encrypted session key, and sends it to the plurality of slaves. A plurality of slaves transmit public keys to a master device, receive and decrypt a session key encrypted using individual public keys, receive data encrypted using the session key from the master, and decrypt it using the decrypted session key. | 09-19-2013 |
20130326086 | COMMUNICATION APPARATUS AND METHOD OF CONTROLLING SAME - A first address set for a first communication interface is acquired from another apparatus. It is determined whether the first address duplicates a second address that has been set for a second communication interface. If it is determined that the first address duplicates the second address, a third address different from the first address is reacquired from the other apparatus. | 12-05-2013 |
20140009780 | COMMUNICATION APPARATUS, METHOD FOR CONTROLLING THE SAME, AND STORAGE MEDIUM - A communication apparatus having a wired interface configured to communicate with another communication apparatus via a wired communication includes a switching unit configured to switch between a first mode enabling a power-saving function in the wired interface and a second mode disabling the power-saving function, a processing unit configured to perform predetermined processing using data received via the wired interface from the other communication apparatus, and a limitation unit configured to limit the switching performed by the switching unit when the processing unit is performing the predetermined processing. | 01-09-2014 |
