Judicial electronic evidence system and method based on alliance chain and homomorphic encryption

Abstract

The invention relates to a judicial electronic evidence system based on an alliance chain and homomorphic encryption. The judicial electronic evidence system comprises a key generation center KGC, a cloud platform CP, a computer server CSP, an evidence storage user side and a notary side. The secret key generation center is connected with the certificate storage user side and the notary side. The cloud platform is connected with the computer server side, the evidence storage user side and the notary side. According to the system and method, the problems that after a traditional centralized judicial electronic evidence system is attacked by a hacker, data is prone to being lost and tampered are solved, and secret calculation can be provided under the condition that privacy of the data and user information in the judicial electronic evidence system is protected.

Description

technical field

[0001] The invention relates to the field of data encryption, in particular to a judicial electronic evidence system and method based on alliance chain and homomorphic encryption. Background technique

[0002] With the emergence of the cloud computing platform, more and more enterprises and individuals hope to use this emerging technology to migrate a large amount of data to the cloud platform. With the rapid development of science and technology, the amount of data is growing at an increasingly rapid rate . A large amount of new data is generated all the time, but many old data face the risks of easy data loss, high storage costs, and easy data tampering, and there is a need for long-term safe and reliable storage. With the development of digitization, and the increasing trend of organizational policies and laws and regulations to preserve data for a specific period of time, there is a growing need for long-term data storage solutions.
