Patent number: 9749449Abstract: A more secure TCP/IP protocol stack is provided having an enhanced transport layer. Encryption and decryption logic is arranged on the transmission side and on the reception side for processing a payload of a transport layer protocol, such as TCP or UDP. By employing this enhanced transport layer, a cryptograph process communication can be realized by dissolving various kinds of restrictions which a conventional IPsec or SSL possesses without affecting upper layer processing, and, at the same time, maintaining compatibility with the IP layer.Type: GrantFiled: October 18, 2013Date of Patent: August 29, 2017Assignee: INTO CO., LTD.Inventors: Hirotsugu Ozaki, Keiko Ogawa

Publication number: 20160094520Abstract: A network gateway apparatus which adds encryption to easily implement secure communication without affecting network environment settings includes two network interface cards to communicate on two networks. The processor of the network gateway apparatus initializes communications through the network interface cards and uses a TCP/IP protocol stack to communicate through the network interface cards. When a packet is received by one of the network interface cards, the processor replaces the origin MAC and IP addresses and the destination MAC and IP addresses with temporary values. Then the processor encrypts the payload. The packet is sent to the TCP/IP protocol stack, which sends the packet to one of the two network interface cards according to the temporary values. The MAC an IP addresses of the final destination of the packet are rewritten to the packet and the packet is transmitted.Type: ApplicationFiled: December 8, 2015Publication date: March 31, 2016Applicant: INTO CO., LTD.Inventor: Keiko OGAWA

Patent number: 8824674Abstract: An information distribution system described herein is capable of securely storing digitized personal information in an encrypted state in a storage section and securely transferring/disclosing the stored digitized information only to a particular third person via a network. Communication of the information is securely performed in the encrypted state between information terminals connected to the communication network. An information terminal which has created information encrypts the original information by a common key generated upon communication and stores the information in a secure storage of one of the information terminals connected to the communication network while maintaining the encrypted state. Further, the system creates a mechanism for authenticating a person having a particular authority for viewing the encrypted information and index information having an encrypted common key and link information indicating the location of the information for supply to a user.Type: GrantFiled: February 19, 2013Date of Patent: September 2, 2014Assignee: INTO Co., Ltd.Inventor: Keiko Ogawa
