아이디 기반 암호화 및 서명 장치 및 방법이 제공된다. 아이디 기반 암호화 및 서명 장치의 암호화부는 제1파일을 수신할 수신자의 ID(identification)가 입력되면, 수신자의 ID를 공개키로서 이용하여 상기 제1파일을 암호화하고, 파일 생성부는 수신자의 ID를 암호화된 제1파일의 파일명 중 일부로 설정하고, 제1파일이 암호화되었음을 나타내는 암호화용 확장자를 제1파일의 확장자로 하여 암호화 파일을 생성한다.
Abstract:
PURPOSE: An ID based encoding and signature device and a method thereof are provided to use ID which is used for ID based encoding as a file name and to use a dedicated extension which shows the encoding or a signature, thereby enabling recognition for a file which security is applied. CONSTITUTION: When ID of a receiver who receives a first file is inputted, an encoding unit(152) encodes the first file by using the ID of the receiver as a public key. A file generation unit(153) sets the ID of the receiver as a part of a file name of the first file. The file generation unit generates an encoding file by using an encoding extension as an extension of the first file. The file generation unit sets an original file name, an original extension, and an identifier of the first file and the ID of the receiver as a file name of the encoding file.

PURPOSE: A customer transmitting and caching method and a system therefor are provided to control balance between the links by reducing traffic amount between the ISP(Internet Service Providers). CONSTITUTION: A host(320) request content, a content server(310) stores the content, and a network connects the host and the content server. The network comprises entities(210~230) including a content storing unit capable of storing the content according to the popularity of the content. The entities comprise a content transmitting unit transmitting the stored content to the host and a content distribution unit distributing the content to other entities according to the popularity of the content.

Abstract:
PURPOSE: A diary-based SNS(Social Network Service) providing method and a system using the same are provided to supply an SNS through tagging information, thereby forming a new social network with experts or people having common interests. CONSTITUTION: A request for using a diary-based SNS is received from a user terminal in order to make a user tag list(S210). The user tag list composed of tags obtained by the user terminal is made(S220). A social network is formed between a user and other users based on the tags of the user tag list(S230). A diary is made based on the user tag list and the social network related to the tags of the user tag list(S240). [Reference numerals] (AA) Diary-based SNS providing method; (S210) Receiving a request for using a diary-based SNS; (S220) Making a user tag list; (S230) Social network formation; (S240) Writing a diary
Abstract:
단말 중심의 네트워크 (endpoint-oriented network) 와 컨텐트 중심의 네트워크 (Content-oriented network) 가 결합된 하이브리드 네트워크 시스템을 제안한다. 인터넷의 접속이나 웹 서핑 등과 같이 대화 중심의 네트워킹에 대해서는 단말 중심의 네트워크로 접속되고, 영화, 음악 등의 대용량의 컨텐트 데이터를 전송하는 경우에는 컨텐트 중심의 네트워크로 접속된다. 하이브리드 네트워크
Abstract:
데이터센터 네트워크에서의 부하 균형을 위한 신용 기반 다중경로 데이터 전송 방법으로서, 수신 장치에게 신용 요청 패킷을 전송하는 단계; 신용 요청 패킷에 대한 응답으로, 수신 장치로부터, 수신 장치와 통신이 가능한 모든 경로 중 신용 패킷이 가장 먼저 수신되는 적어도 하나의 제1 경로를 결정하는 단계; 및 수신 장치로부터 제1 경로를 통해 신용 패킷이 수신될 때마다, 신용 패킷에 응답하여 제1 경로를 통해 수신 장치에게 데이터 패킷을 전송하는 단계 - 제1 경로를 통해 수신한 신용 패킷과 제1 경로를 통해 수신 장치에게 전송된 데이터 패킷은 일대일 대응됨 -; 수신 장치에게 전송할 잔여 데이터 패킷이 더 이상 존재하지 않는 경우, 수신 장치에게 신용 중지 패킷을 전송하는 단계를 포함하는, 신용 기반 다중경로 데이터 전송 방법이 제공된다.
Abstract:
The present invention relates to a method and an apparatus for delivering contents over a named data network (NDN). According to a first aspect of the present invention, a method for delivering contents in a content delivery system configured to deliver packets from one node to another node, based on an open flow network system including multiple nodes configured to transmit and receive packets using content names, a switch device configured to relay a flow transmission/reception among the multiple nodes, and a controller device configured to control the switch device, comprises the following steps. When a packet is received, the switch device determines whether the received packet is a packet to be delivered over the NDN. And, when the received packet is the packet to be delivered over the NDN, the switch device acts as an entity of the NDN based on a type of the packet. By using the present invention, an NDN which utilizes a pre-established network is configured.
