Abstract
A terminal apparatus is connected to a content-centric network and includes: a processor; and a non-transitory memory having stored therein instructions which, when executed by the processor, cause the processor to perform operations including encrypting a name of content data with a predetermined encryption key to convert the content data name into a first character string and generating a request packet in which a character string including a second character string indicating a name of a gateway apparatus and the first character string is stated as the content data name, and sending the generated request packet to the network.
Claims17
A terminal apparatus connected to a content-centric network, the terminal apparatus comprising:
- a processor;
- and
- a non-transitory memory having stored therein instructions which, when executed by the processor, cause the processor to perform operations comprising:
- encrypting a name of content data with a predetermined encryption key to convert the content data name into a first character string,
- generating a request packet in which a character string is stated as the content data name, the character string including a second character string indicating a name of a gateway apparatus and the first character string, and;
- sending the generated request packet to the network.
A gateway apparatus connected to a content-centric network, the gateway apparatus comprising:
- a processor;
- and
- a non-transitory memory having stored therein instructions which, when executed by the processor, cause the processor to perform operations comprising:
- receiving, as a name of content data, a request packet including a character string including a second character string indicating a name of the gateway apparatus and an encrypted first character string;
- converting the received request packet by extracting the encrypted first character string from the received request packet, decrypting the extracted encrypted first character string with a predetermined decryption key, and generating a request packet in which the decrypted first character string is included as the content data name;
- and
- sending the converted request packet to the network.
A relay apparatus connected to a content-centric network to relay a request packet and a data packet, the relay apparatus comprising:
- a processor;
- and
- a non-transitory memory having stored therein instructions which, when executed by the processor, cause the processor to perform operations comprising:
- receiving a request packet including a character string in which a second character string indicating a name of the relay apparatus and a first character string is included as a name of content data;
- converting the received request packet by extracting the first character string from the received request packet, decrypting the extracted first character string with a predetermined decryption key, and generating a request packet in which the decrypted first character string is included as the content data name;
- and
- sending the converted request packet to the network.
A communication method for a terminal apparatus connected to a content-centric network to send a request packet stating a name of content data and to receive a data packet including the content data, the communication method comprising:
- encrypting the content data name with a predetermined encryption key to convert the content data name into a first character string and generating a request packet in which a character string is stated as the content data name, the character string including a second character string indicating a name of a gateway apparatus and the first character string, and;
- sending the request packet generated in the generating of the request packet to the network.
A communication method for a gateway apparatus connected to a content-centric network, the communication method comprising:
- receiving a request packet including a character string in which a second character string indicating a name of the gateway apparatus and a first character string is included as a name of content data;
- converting the request packet received in the receiving of the request packet, by extracting the first character string from the received request packet, decrypting the extracted first character string with a predetermined decryption key, and generating a request packet in which the decrypted first character string is included as the content data name;
- and
- sending the request packet converted in the converting of the request packet to the network.
A communication method for a relay apparatus connected to a content-centric network to relay a request packet and a data packet, the communication method comprising:
- receiving a request packet including a character string in which a second character string indicating a name of the gateway apparatus and a first character string is included as a name of content data;
- converting the request packet received in the receiving of the request packet, by extracting the first character string from the received request packet, decrypting the extracted first character string with a predetermined decryption key, and generating a request packet in which the decrypted first character string is included as the content data name;
- and
- sending the request packet converted in the converting of the request packet to the network.
