AT32讲堂 | 雅特力AT32 MCU的随机数生成
概 述
产品和生态系统安全性的需求比以往任何时候都更加重要。真随机数是所有安全系统的核心,其质量会影响设计的安全性。
因此在没有内置硬件TRNG的AT32的微控制器系列中,如何提高随机数的有效,来符合应用的需求。底下提供两种方法:
提高乱度的方法之一,使用ADC的误差。AT32的微控制器内置最多三个高级12位片上SAR模拟数字转换器(ADC)并提供自校准功能,保证12位ADC静态准确度(accuracy)可达10位以上。这误差可以拿来计算随机数的来源。
提高乱度的方法之二,使用上电时SRAM内容的不确定性。SRAM不保证上电时的内容值,每次上电后,内容也是不容易预测的。我们可以利用这个特性,拿来增加随机数的乱度。
利用ADC的误差来源产生随机数的方法
本章介绍了使用软件触发方式触发ADC,配置普通信道和DMA。根据随机数需要的位数来配置信道数,一次转换最多到16信道,将16信道转换的数值可组合计算成一个32位的随机数。底下是DMA和ADC的配置代码。
● DMA配置函数代码
●ADC配置函数代码
可以看到,代码中并没有对ADC做自校准,转换时间也使用最短的,这种情况下,ADC的准确度会是最差的,有助于乱度的提升。
●ADC随机数取得代码
利用上电时SRAM的内容来计算随机数的方式
这范例只是简单的利用累加来获得一个随机数
●SRAM配置函数代码
随机生成应用指南
以上两种方式建议应用在上电后执行,因为SRAM内容在运行后会初始化,ADC也会有其他应用上的需求,上电后执行并获得一个随机数,将这个随机数当成Seed,之后可以利用标准C函式库中提供的随机数生成器,产生后续的随机数。
SRAM的方式限定在POR后使用。如果只是一般的reset,SRAM会维持内容,造成产生的随机数都是相同。
ADC的方式则没有限制,但是因为使用ADC外设的资源,推荐放在开机时执行,不会影响后续的ADC应用。
范例运行和分析
本篇应用笔记适用于AT32各系列MCU,只要有ADC外设皆可适用。范例固件AN0175_SourceCode_V2.0.0运行在AT32403A AT-START版上,透过 PuTTY(免费开源终端仿真器)等终端仿真应用程序,将数据存储在工作站上。在工作站上编译NIST统计测试集程序包,以生成可执行程序。接下来运行NIST统计测试集程序分析数据以及统计测试。
以下是使用范例固件AN0175_SourceCode_V2.0.0在上电后会产生的一个随机数,在收集约319万笔随机数后,进行NIST统计测试。
