Problems solved by technology

But APIP only supports one-to-one communication mode, because in this architecture, the packet fingerprint (fingerprint) used for verification is generated based on network flow (Network flow) information, so the same sender sends the same content to Different recipients will generate different verification information

Embodiment Construction

[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0032] 1. Architecture design

[0033] In order to achieve the goal of balancing privacy protection and behavioral accountability in a content-based network, the present invention proposes a transmission mechanism compatible with traditional networks, and designs a new type of content identifier and corresponding address representation.

[0034] 1. Address format

[0035] In this solution, the address information mainly includes three parts: destination address, proxy address, and return address. The format is shown in Table 1. The return address is optional. The destination address and proxy address must be included.

[0036] Table 1 address format

[0037] address type Format Destination address NIDs D :HID D :CID D ...

Abstract

The invention relates to a method and system for balancing privacy protection and behavior accountability in a content transmission-based network. In the method, a local proxy device is set in the network domain of the content requester, and a source proxy device is set in the network domain of the content provider; the local proxy device receives the summary information of the request packet sent by the content requester; the source proxy device receives the content provided The summary information of the content data packet sent by the author; the local proxy device or the source proxy device receives the verification request initiated by the intermediate node, and through the stored summary information, verifies whether the content requester or content provider has sent the corresponding request packet or content data packet, and verify that the request or content packets have not been reported as malicious requests or malicious content. If the behavior of the content sender has caused adverse effects or huge losses, behavioral accountability can be achieved. The invention can realize the purpose of balancing privacy protection and behavior accountability in a network mainly based on content transmission.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method and system for balancing privacy protection and behavior accountability in a network mainly based on content transmission. Background technique [0002] With the rapid development of the Internet, network security has gradually received widespread attention. Among them, the supervision and "accountability" of user behavior is one of the most concerned issues of network service providers and content providers. In other words, when a user sends a malicious request (or malicious content), the operator and the receiver (the receiver of the request or the receiver of the content) need to find and punish the malicious user (Bender A, Spring N, Levin D, et al., "Accountability as a service," in Proc. IEEE SRUTI'07, 1-6, 2007.). But on the other hand, network users want to protect their privacy, that is, when sending or requesting content, their personal a...
