背景技术Background technique

随着生活水平的提高和技术的成熟，智能家居系统日益普遍，但在实际应用中，大部分智能家居提供商使用的都是在互联网上部署云端服务器的方式来对家居设备进行统一的远程控制，将用户数据都集中储存在云端服务器里，一旦断网或云端服务器崩溃，所有家居设备将失去控制，给用户生活造成了极大麻烦。同时由于用户数据都储存在云端服务器，用户隐私容易发生泄漏或者恶意修改，更严重的是如果被漏洞攻击和远程劫持，远程操控用户的家居设备，可能会造成极大的隐私泄漏和人身安全。With the improvement of living standards and the maturity of technology, smart home systems are becoming increasingly common. However, in practical applications, most smart home providers use a method of deploying cloud servers on the Internet to perform unified remote control of home equipment. The user data is stored in the cloud server in a centralized manner. Once the network is disconnected or the cloud server crashes, all household equipment will lose control, causing great trouble to the user's life. At the same time, because user data is stored in the cloud server, user privacy is prone to leak or malicious modification. What is more serious is that if the user is attacked by a vulnerability and remotely hijacked, remote control of the user's home equipment may cause great privacy leakage and personal security.

近年来，随着区块链技术的快速发展，其分布式建立的信任机制，使数据具有不可更改和不可撤销的特点，具有极大的应用前景，同时由于区块链的私有链具有交易速度快、数据不公开隐私有保障、交易成本低甚至为零、不破坏原有产品的生态体系的优点，在银行清结算、证券交易、互联网金融、版权保护、互联网彩票、电子合同等领域得以广泛应用，而在智能家居领域暂无行业应用。In recent years, with the rapid development of blockchain technology, its distributed established trust mechanism makes data irrevocable and irrevocable, and has great application prospects. At the same time, the blockchain's private chain has transaction speed It is fast, data is not disclosed, privacy is guaranteed, transaction costs are low or even zero, and the advantages of the original product ecosystem are not damaged.It is widely used in bank settlement, securities trading, internet finance, copyright protection, internet lottery, electronic contracts Applications, but no industry applications in the field of smart home.

所述Hash值为采用哈希算法对任意内容计算出一个长度相同的特征值，区块链的哈希长度是256位，无论原始数据不管为何种，都可计算出唯一一个256位的二进制数字，而且可以保证，只要原始内容不同，对应的Hash值一定不同。因此，任一区块的区块体内的数据遭到改动，一定会导致该区块体的Hash值发生改变，然后影响到下一区块的区块体内记录的上一区块Hash值也发生改变，由此引起连锁反应，使得区块链主链中的数据一旦写入就不可更改、不可撤销。The Hash value uses a hash algorithm to calculate a feature value of the same length for any content. The hash length of the blockchain is 256 bits. No matter what the original data is, a unique 256-bit binary number can be calculated. And it can be guaranteed that as long as the original content is different, the corresponding hash value must be different. Therefore, if the data in the block body of any block is changed, the hash value of the block body must be changed, and then the hash value of the previous block recorded in the block body of the next block will also be changed. Changes cause a chain reaction, making the data in the main chain of the blockchain irreversible and irrevocable once written.
