一种量子网络的可信数据区块链存证方法

Trusted Data Blockchain Certificate Storage Method Based on Quantum Network

区块链因其无法更改、全程留痕的特性被广泛应用于交易、版权和产品溯源存证中,随着区块链的大规模商用,在数据上链的环节中数据被篡改成为一种新型攻击方式。基于量子通信技术的安全性,介绍了使用量子网络技术解决在网络层传输数据时可能被篡改的防御方法,该量子网络技术不仅可以提高数据上链和安全性,还可以提高上链效率。

Blockchain is widely used in transactions,copyrights and product traceability certificates due to its inherent characteristics of unchangeable and traceability.With the large-scale commercial usage of the blockchain,data tampering in the link of data chain has became a new type of attack.This paper introduces the defense method of using quantum network technology to prevent the possible tampering when transmitting data at the network layer,and it will be used in the Tianquan blockchain content traceability platform,which is self-developed by Nanjing Broadcasting group.
