Quantum-based content centric network privacy protection method

Abstract

The invention provides a quantum-based content centric network privacy protection method, which comprises the following steps of: encrypting and aggregating a classical ciphertext by using an ELGamal algorithm: generating a main public key according to public and private key pairs generated by all participants, generating a ciphertext according to plaintext information of the participants, sending the ciphertext to a cloud server, aggregating according to the ciphertext to obtain an aggregated ciphertext, and generating a classic message to be shared according to the aggregated ciphertext; in the quantum encryption stage, in all interaction processes with the cloud server, enabling a data owner to convert classic information into quantum information and negotiate a shared key with the cloud server through a BB84 key negotiation protocol, wherein each data person encrypts the quantum information by using the shared key; and detecting the eavesdropping behavior through adoption of a method of randomly inserting the decoy particles, so that the safety has double assurance. According to the method, confidentiality of sensitive content exchange between a publisher and a user is guaranteed, the method can be effectively executed under the condition that any privacy information is not leaked, and the content can be safely shared and aggregated.

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 sum of traffic in all 32 years from the first year of the Internet to the end of 2016. Among them, most of the traffic will originate from content acquisition applications. It is estimated that by 2025, IP video traffic alone will account for 82% of all IP traffic (commercial and consumer), and traffic generated by consumer-driven digital video content will continue to grow at a high rate in the next few years. In order to adapt to changes in future traffic trends, researchers must provide native support for scalable and efficient content acquisition from the network system, while enhancing network support for mobility and security. Therefore, the d...
