  • Publication number: 20200220724
    Abstract: A reception unit receives a key request including a communication apparatus identifier and a terminal apparatus identifier. An apparatus key generation unit generates a communication apparatus key using the communication apparatus identifier included in the key request, and generates a terminal apparatus key using the terminal apparatus identifier included in the key request. A shared key generation unit generates an encrypted shared key of the communication apparatus by encrypting a shared key using the generated communication apparatus key, and generates an encrypted shared key of the terminal apparatus by encrypting the shared key using the generated terminal apparatus key. A transmission unit transmits a key reply including the encrypted shared key of the communication apparatus and the encrypted shared key of the terminal apparatus.

  • Patent number: 10455630
    Abstract: An image forming apparatus 100 that can prevent an unnecessary deterioration of data transmission performance. The image forming apparatus 100 has a MTU value input screen 600 including options representing different MTU values each of which can be selected. When it is determined that a present communication mode is a second communication mode realized without directly connecting the image forming apparatus 100 and the external apparatus, the selected MTU value is set as an acceptable amount of the data to be transmitted in a communication between the image forming apparatus 100 and the external apparatus. When it is determined that the present communication mode is a first communication mode realized by directly connecting the image forming apparatus 100 and the external apparatus, a maximum transmittable amount of the data in the first communication mode is set as the acceptable amount of the data to be transmitted.

  • Publication number: 20190305825
    Abstract: A technique by which it is possible to prevent a user inputting mistake from occurring when writing, from a communication apparatus (communication terminal) to a wireless communication tag (NFC tag), connection information for connecting to a printing apparatus (image forming apparatus) is provided. The image forming apparatus converts connection information for connecting to the image forming apparatus by a WLAN scheme into a corresponding image pattern, and displays the image pattern on a display unit. A communication terminal photographs the image pattern displayed on the display unit by a camera. The communication terminal restores the corresponding connection information from the image pattern photographed by the camera, and generates NDEF data based on the restored connection information. The communication terminal writes the generated NDEF data to the NFC tag by NFC communication.

  • Patent number: 10382923
    Abstract: A communication apparatus that is capable of preventing data erroneous transmission without disturbing communication with a networking device. The communication apparatus is connectable with a plurality of networks including at least a first network and a second network. A specifying unit specifies an IP address of the communication apparatus that is used in communication with an external apparatus on the first network. A determination unit determines an IP address of which a network part is different from a network part of the IP address specified by the specifying unit as an IP address that will be distributed to an external apparatus on the second network. A distribution unit distributes the IP address determined by the determination unit to the external apparatus on the second network.

  • Patent number: 9241371
    Abstract: A communication apparatus for performing communication with a communication terminal, and a method of controlling the same. The apparatus performs wireless communication with the communication terminal by a first wireless communication mode and performs wireless communication with the communication terminal by a second wireless communication mode in which either the communication apparatus or the communication terminal becomes an access point. The apparatus receives a switching instruction of communication mode from a user, and determines whether or not the switching of the communication mode in accordance with the received switching instruction is executable, makes a request for an additional instruction to the user when it is determined that it is not executable, and controls the switching of the communication mode in accordance with an additional instruction in response to the request.

  • Publication number: 20150347073
    Abstract: A communication apparatus capable of executing a wireless communication includes an identification unit, a display unit, a notification unit, and a connection unit. The identification unit identifies a communication partner of the wireless communication. The display unit displays, if an external apparatus which is the communication partner of the wireless communication is identified by the identification unit, a confirmation screen for allowing a user to confirm whether to execute the wireless communication with the external apparatus. The notification unit notifies, if the confirmation screen is displayed by the display unit, the external apparatus that the user is confirming whether to execute the wireless communication. The connection unit executes, if the user issues an instruction via the confirmation screen to execute the wireless communication with the external apparatus, connection processing for executing the wireless communication with the external apparatus.

  • Patent number: 9137207
    Abstract: An object of the present invention is to more appropriately filter a packet from an external device. This object is achieved by: obtaining address information of the external device from the packet; judging whether or not the address information of the external device has been registered as filter information; extracting, when it is judged that the address information has not been registered, device discrimination information of the external device from the address information of the external device; judging whether or not address information having the same device discrimination information as the extracted device discrimination information has been registered as the filter information; and registering, when it is judged that the address information having the same device discrimination information has been registered, the address information of the external device as the filter information.
