同态加密算法和区块链在建筑行业的应用

Application of Homomorphic Encryption Algorithm and Blockchain in Construction Industry

由于区块链中大量流通的交易信息数据公开透明,而且不可随意被篡改,区块链中所有的交易记录都是通过分析和计算,可以轻松地实现跟踪交易金额和交易地址,甚至还能直接从网络上查找得到真实用户的信息,造成用户信息及隐私被泄露,不利于对个人或者其他组织的合法隐私进行保护。因而,加密和保存区块链上所有数据信息对于区块链上所有用户安全和隐私得到保护是十分重要的。以当前区块链的架构设计及其加密原理,传统区块链的交易模式和加密方法已经失去了保护用户数据隐私的作用,用户在区块链中的所有交易和加密信息全部清晰可见,论文以全同态加密算法为基础,尝试把POS技术引入一种基于全同态加密的区块链协议,尝试与建筑业结合来研究如何保护数据隐私区块链的实际可行性。

Because a large number of transaction information data in the blockchain are open and transparent and can not be tampered with at will,all transaction records in the blockchain can easily track transaction amount and transaction address through analysis and calculation,and even can find real user information directly from the network,which causes the disclosure of user information and privacy,it is not conducive to the protection of the legitimate privacy of individuals or other organizations.Therefore,it is very important to encrypt and save all data information in the blockchain for the protection of all users'security and privacy.Based on the current blockchain architecture design and encryption principle,the traditional blockchain transaction mode and encryption method have lost the role of protecting the privacy of user data.All the transactions and encryption information of users in the blockchain are clear and visible.Based on the full homomorphic encryption algorithm,this paper attempts to introduce POS technology into a blockchain protocol based on full homomorphic encryption,This paper attempts to study the feasibility of how to protect the data privacy blockchain by combining with the construction industry.
