Problems solved by technology

At present, when NDN routers verify the content, they all use asymmetric encryption to verify. Although this verification method can detect whether the content is contaminated, the verification speed under the asymmetric encryption method is too slow to meet the needs of high-speed networks. environmental needs

Embodiment Construction

[0047] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0048] The technology described in this article is not limited to CCN / NDN networks, but can also be used in a variety of content center networks.

[0049] Hereinafter, some terms in the embodiments of the present invention will be explained to facilitate the understanding of those skilled in the art.

[0050] (1) The network device can forward data packets. In some embodiments, the network device can also generate data packets. Network equipment may include routers, switches, network management, or network cards and other equipment. This article uses routers as an example in the description.

[0051] (2) CCN / NDN data packets are roughly divided into two categories: Interest packets and Data packets. The Interest packet is a reques...

Abstract

Disclosed is a content verification method and device used for accelerating the speed of content verification. The method includes the following steps: a first network device receives a first data packet sent by a second network device, wherein the first data packet carries a first content; if the first data packet carries first symmetrical encryption information and the first symmetrical encryption information is used for verifying the first content in a trusted domain in which the first network device is located, the first network device verifies the validity of the first content carried bythe first data packet according to the first symmetric encryption information; and if the first content is valid, the first network device processes the first data packet according to a transmission path of the first data packet.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communication technology, and in particular to a content verification method and device. Background technique [0002] The Internet mechanism with Internet Protocol (IP) packet switching as its core technology has been widely used for more than 20 years. This is because the simplicity of the IP protocol itself reduces the cost of network interconnection and enhances network adaptability. But from the perspective of technological development, the original goal of the Internet is to pursue the interconnection of the network to realize the sharing of hardware resources. Since the initial communication requirement occurred between two physical devices, in order to determine the specific location of the device, the Internet uses IP addresses to identify different devices to support data communication between the devices. However, with the advancement of technology and the popularization of informat...
