Example Embodiment

[0029]Example one:

[0030]The data encryption module on the IoT terminal collection device selects modulus n=pq, p, q are prime numbers, and p≡q≡3mod4, hash function H: {0,1}*→Zn*;

[0031]The public key of the data encryption module on the IoT terminal collection device is n, and the private key is p, q;

[0032]The data encryption module collects the data collected and transmitted by the Internet of Things terminal equipment M ∈ Zn, Use the private key p, q to calculate the ciphertext C of the data M, so that s2=H(m)modn, the signature of the generated data M is (m, s);

[0033]Data integrity verification module verification for smart city big data centers2=H(m)modn;

[0034]Among them, the digital signature of the data encryption module can establish an anti-counterfeiting mark, make the data unchangeable, and maintain data integrity. In many practical application scenarios of smart cities, the Internet of Things terminal collection equipment and the smart city big data center need to send and...

Abstract

The invention relates to the technical field of smart city data integrity protection, and discloses a data integrity protection platform based on a smart city. The data integrity protection platform comprises a key service system, a data encryption module and a data integrity verification module, wherein the data encryption module encodes and encrypts the acquired data by adopting a secure hash algorithm to generate a digital abstract; the data encryption module encrypts a key to the key service system, and the data encryption module re-encrypts the digital abstract by using a private key to obtain a signature of the data; the data encryption module transmits the data and the signature to a smart city big data center at the same time; and the data integrity verification module compares thedecrypted digital digest with the digital digest generated by re-encrypting the received data, and if the decrypted digital digest is consistent with the digital digest generated by re-encrypting thereceived data, the data is not damaged or tampered and is complete. According to the invention, the problem of incomplete data in the process of smart city construction and information acquisition due to lack of a data integrity protection mechanism is solved.

Description

technical field [0001] The invention relates to the technical field of smart city data integrity protection, in particular to a smart city-based data integrity protection platform. Background technique [0002] The construction of smart cities in the digital economy era uses technologies such as the Internet of Things, cloud computing, and big data. While endowing objects with intelligence and convenient user experience, it also inevitably brings about data integrity issues, such as in the construction of smart cities and information collection. During the process, errors in hardware devices (such as sensors) will lead to loss or incompleteness of collected data; due to the isolation of information between industries or departments, information may also be lost during the process of information sharing. And there is no special verification link for key data. After the data has been tampered with, it cannot be found quickly, or even if it is found, the data cannot be restored...
