摘　　要：区块链技术基于P2P网络技术,具有去中心化结构,用户拥有平等权利。每一个数据块中包含一次网络交易的信息,不可篡改、不可伪造。区块链技术在解决目前集中式物联网方式安全问题具有优势,可以协助解决物联网的安全及可扩展性的问题。在金融交易应用中,使用两个层级的安全机制,在认证和验证过程中分别使用RSA算法和哈希函数,来提高金融交易的信息安全性。Blockchain technology is based on P2P network technology with a decentralized structure and equal rights for users.Each data block contains the information of one network transaction,which cannot be tampered or falsified.Blockchain technology has advantages in solving the security problems of the current centralized IoT approach,and can assist in solving the security and scalability problems of IoT.In financial transaction applications,two layers of security mechanisms are used to improve the information security of financial transactions by using RSA algorithms and hash functions in the authentication and verification processes,respectively.
