基于AES算法的智能家电信息安全的应用

Information Security of Intelligent Home Appliances Based on AES

文章针对智能家电在进行数据传输过程中存在用户信息泄露和遭受恶意篡改的风险,分析了用户隐私信息泄露的途径和不同加解密算法在智能家电中的应用情况。并以经典的对称加密算法AES为例,本文分析了AES各模式的工作特点,并通过将AES算法移植进linux系统进行测试分析,优选出AES-128bit-CTR模式为最佳工作模式。

In view of the risk of user information disclosure and malicious tampering in the process of data transmission of smart home appliances,this thesis analyzes the ways of user infbnnation privacy disclosure and the application of difierent encryption and decryption algorithms in smart home appliances.Taking the classical symmetric encryption algorithm AES as an example,the algorithm is separately extracted from the OpenS SL function library and transplanted to the STM32 single-chip,and the performance of the algorithm is tested by using the Visio Studio2017+Qt software to develop the test interface algorithm.The factors that affect the time-consuming encryption and decryption of user information data are analyzed from two aspects ofkey length and grouping mode.The test analysis shows that the key length is proportional to the time-consuming,and the balance of CTR mode is better than the others.
