一、AES加密功能在物联网行业中的应用

AES加密功能在物联网行业中有着广泛的应用。随着物联网技术的不断发展,越来越多的设备连接到互联网上,这也增加了数据泄露和网络攻击的风险。为了保护物联网设备和传输的数据的安全,AES加密技术被广泛应用于以下几个方面:
  • 数据传输加密:物联网设备之间传输的数据可以使用AES加密算法进行加密,确保数据在传输过程中不被窃取或篡改。
  • 身份验证:AES加密技术可以用于物联网设备的身份验证过程,确保只有合法的设备可以接入物联网网络。
  • 安全存储:物联网设备上存储的数据可以使用AES加密算法进行加密,确保数据在设备丢失或被盗时不会被泄露。
总的来说,AES加密技术在物联网行业中的应用可以提高设备和数据的安全性,保护用户的隐私和权益。

二、AES加密功能的行业知识介绍

1.AES加密算法定义

AES加密算法(Advanced Encryption Standard)是一种对称加密算法,也称为高级加密标准。它是由美国国家标准与技术研究院(NIST)于2001年发布,作为DES加密算法的替代方案。AES加密算法使用128位、192位或256位密钥对数据进行加密和解密,具有高强度、高速度和易于实现等优点。

2.AES加密算法的原理是什么?

密钥扩展
根据AES密钥长度进行密钥扩展,生成多个轮密钥。
初始轮
将明文数据分成128位块,并与第一个轮密钥进行异或操作。
多轮加密
重复进行多轮加密操作,每轮操作包括四个步骤:
字节替换:将每个字节映射到另一个字节,使用S-Box进行替换。
行移位:对每个128位块的行进行循环左移,第一行不移动,第二行左移1个字节,第三行左移2个字节,第四行左移3个字节。
列混淆:对每个128位块的列进行混淆,使用固定矩阵进行乘法运算。
轮密钥加:将每个128位块与下一个轮密钥进行异或操作。
最终轮
最后一轮加密后,将128位块与最后一个轮密钥进行异或操作。
输出
输出所有块的加密结果作为密文。

3.AES加密算法的安全性如何?

密钥长度
AES加密算法支持128位、192位和256位密钥长度,密钥长度越长,加密强度越高,可以有效抵御暴力破解和其他攻击。
算法的强度
AES加密算法采用了高度复杂的算法,包括字节替换、行移位、列混淆等多重操作,使得攻击者很难找到有效的攻击路径。
随机性和扩散性
AES加密算法具有良好的随机性和扩散性,能够抵御差分密码分析和其他密码分析攻击。
算法的公开性
AES加密算法是一种公开的加密算法,任何人都可以使用和实现,这也促进了算法的安全性和可信度。

4.AES加密算法的优点是什么?

安全性高
AES加密算法是一种安全性较高的加密算法,能够有效抵御暴力破解和其他攻击。
加密速度快
AES加密算法的加密速度相对较快,尤其是对于128位密钥长度的加密,可以在硬件上实现高速加密。
硬件实现方便
由于AES加密算法采用了固定的算法结构,因此可以在硬件上实现高效加密。
兼容性好
AES加密算法已经被广泛应用,许多软件和硬件设备都支持该算法。
可扩展性强
AES加密算法的密钥长度可选128位、192位和256位,可以根据安全需求选择密钥长度。
开放性好
AES加密算法是一种公开的加密算法,任何人都可以使用和实现。

5.AES加密算法的缺点是什么?

算法复杂度高
AES加密算法的加密过程需要进行多次复杂的操作,包括字节替换、行移位、列混淆等多重操作,因此算法复杂度较高。
密钥管理困难
AES加密算法需要使用较长的密钥长度,密钥管理较为困难,需要特殊的管理措施来保证密钥的安全性。
密文长度固定
AES加密算法的密文长度固定,无法根据明文长度动态调整,可能会对某些应用场景造成限制。
密文块的处理
由于AES加密算法是基于块密码算法,因此对于大文件的加密需要分块处理,可能会导致加密速度变慢。
可重放攻击
在某些情况下,攻击者可以通过重放加密数据来实现攻击,这是AES加密算法的一个安全漏洞。

2.基于红豆平台调用AES加密组件的demo示例:

2.1 创建一个Demo
复制20.2_at_xtu示例工程,到同一个文件夹下,修改文件名为22.1_aes_cipher,如图:
2.2 修改makefile
增加文件组件所在目录头文件路径,和源文件路径,以及一些宏定义,如图:
2.3 增加头文件
使用代码编辑器,将新建的工程文件加入代码编辑器中,打开main.c,修改main.c,加入am.h头文件,如图:

2.4 修改代码
示例使用的是板载5x6卡,用户的硬件可能是使用外置卡,或者是三合一全网通卡,因为硬件上三种卡使用的模组SIM卡接口不一样(外置卡SIM1,5x6卡和三合一卡SIM2),所以,需要通过一个全局变量来制定SIM卡硬件接口。
在Phase2Inits_exit 调用文件组件提供的对外API,如图:
修改main函数中,实现加密解密API调用
2.5 编译
在SDK根目录打开命令行,输入命令.\build.bat -l .\amaziot_bloom_os_sdk\sample\libraries\22.1_aes_cipher\

2.6 生成固件
参考入门中开发工具,生成工具。
2.7 查看现象
固件下载到模组,设置参数连接服务器,发送透传数据,查看服务器数据是否按照配置上报。
配置为AT+FMCFG=1,上报为十六进制数据。配置AT+FMCFG=2,上报JSON数据(注意配置为2,只支持字符串透传,十六进制尽量配置为1)

四、如何了解更多AES加密功能
