Abstract

The invention discloses a multi-layer encryption privacy protection method used for content-centric networking. The multi-layer encryption privacy protection method comprises the steps that: a requester sends an interest package used for creditability validation to a publisher of content, and the publisher responds to the requestor; the requestor sequentially uses a publisher public key and a router public key for encrypting the requested interest packet, and sends the requested interest packet to a router; the router decrypts the requested interest packet by using a private key to obtain information it needs, and then forwards the requested interest packet to the next-layer router until the requested interest packet is sent to the publisher; the publisher decrypts the requested interest packet by using a publisher private key, validates the creditability of the requester, responds to the requested interest packet when the validation passes, and sends data to the router; and the router decrypts a data packet by using a private key to obtain response data, and forwards the response data to the next-level router until the response data is forwarded to the requester. The multi-layer encryption privacy protection method adopts the public keys for encryption, is relatively high in security, and can protect the privacy of the requestor and the publisher to a greater extent.

Description

technical field [0001] The invention relates to the field of content CITIC network research, in particular to a multi-layer encryption privacy protection method for content-centric networks. Background technique [0002] With the rapid development of the Internet, the traditional IP network architecture has exposed many disadvantages, and it has been difficult to meet the development requirements of the current Internet. In order to adapt to the development of the times, since 2006, academic circles at home and abroad have carried out research on new network architectures, including the data-oriented network architecture (DONA, data-oriented network architecture) (KOPONEN T , CHAWLA M, GON C B, et al.A data-oriented(and beyond) network architecture[A].Proceedings of the ACM SIGCOMM2007Conference[C].Kyoto,Japan,2007.181-192.), Palo Alto Research Center Center network (CCN, content-centric networking) (European Union.Project FP7 4WARD[EB / OL].http: / / www.4wardproject.eu,2010), ...
