A quantum-based privacy protection method for content-centric networks

Abstract

The present invention proposes a quantum-based content-centric network privacy protection method, the steps of which are as follows: encrypt and aggregate classical ciphertext by using the ELGamal algorithm; generate a master public key according to the public-private key pair generated by all participants; Generate the ciphertext and send it to the cloud server, aggregate the ciphertext to obtain the aggregated ciphertext, and generate the classical message to be shared according to the aggregated ciphertext; Quantum encryption stage: During all interactions with the cloud server, the data owner converts the classical information It generates quantum information, and negotiates a shared key with the cloud server through the BB84 key agreement protocol, and each data user uses it to encrypt the quantum information; it also detects eavesdropping behavior by randomly inserting decoy particles, making its security double-guaranteed . The present invention ensures the confidentiality of sensitive content exchanged between publishers and users, can be effectively executed without revealing any private information, and can safely share and aggregate content.

Description

technical field [0001] The invention relates to the technical field of privacy protection, in particular to a quantum-based content-centric network privacy protection method. Background technique [0002] Recently, Cisco released a report predicting that by 2022, the IP traffic flowing through the global network will exceed the total traffic of the entire 32 years from the first year of the Internet to the end of 2016. Among them, most of the traffic will come from content acquisition applications. IP video traffic alone is expected to account for 82% of all IP traffic (commercial and consumer) by 2025, and traffic generated by consumer-driven digital video content will continue to grow at a high rate for years to come. In order to adapt to the changing traffic trends in the future, researchers must provide native support for scalable and efficient content acquisition from the perspective of network architecture, while enhancing network support for mobility and security.
