Design of Blockchain Transaction Data Privacy Protection System Based on Homomorphic Encryption

为了解决由于数据识别效果较差引起的加密效率低的问题,提出基于同态加密的区块链交易数据隐私保护系统设计。系统的硬件设备包括处理器和数据采集器,利用数据采集器对需要加密的交易数据进行捕捉,并在处理器中进行匹配,实现对加密数据的精准识别。处理器运用同态加密算法建立相应的加密及解密机制,对采集器捕捉到的交易数据进行加密。测试结果表明,设计系统可以实现对交易数据的快速加密和解密,具有较高的运行效率。

In order to reduce the problem of low encryption efficiency caused by the poor data recognition effect,a blockchain transaction data privacy protection system design based on homomorphic encryption is proposed.The hardware devices of the system are the processor and the data collector.In the software,the data collector is used to capture the transaction data that needs to be encrypted,and the processor is matched to realize the accurate identification of the encrypted data.The processor uses homomorphism The encryption algorithm establishes a corresponding encryption and decryption mechanism to encrypt the transaction data captured by the collector.The test results show that the design system can realize fast encryption and decryption of transaction data,and has high operating efficiency.
