+MindArmour differential privacy module Differential-Privacy implements the differential privacy optimizer. Currently, SGD, Momentum and Adam are supported. They are differential privacy optimizers based on the Gaussian mechanism. 
+This mechanism supports both non-adaptive and adaptive policy. Rényi differential privacy (RDP) and Zero-Concentrated differential privacy（ZDP） are provided to monitor differential privacy budgets. The architecture is shown as follow：

+## 简介
+
+MindArmour可用于增强模型的安全可信、保护用户的数据隐私。
+
+模型安全主要针对对抗样本，包含了4个子模块：对抗样本的生成、对抗样本的检测、模型防御、攻防评估。对抗样本的架构图如下：
+

+
+隐私保护支持差分隐私，包括动态或者非动态的差分隐私SGD、Momentum、Adam优化器，噪声机制支持高斯分布噪声、拉普拉斯分布噪声，差分隐私预算监测包含ZDP、RDP。差分隐私的架构图如下：

+
+## 开始
+
+### 环境依赖
+
+MindArmour使用MindSpore加速计算，因此请先安装MindSpore，其余依赖包含在`setup.py`里。
+
+### 安装
+
+#### 源码安装
+
+1. 从Gitee下载源码。
+
+```bash
+git clone https://gitee.com/mindspore/mindarmour.git
+```
+
+2. 编译安装MindArmour。
+
+```bash
+$ cd mindarmour
+$ python setup.py install
+```
+
+#### `Pip`安装 
+
+1. 从[MindSpore官网](https://www.mindspore.cn/versions/en)下载whl格式的安装包，然后执行如下命令：
+
+```
+pip install mindarmour-{version}-cp37-cp37m-linux_{arch}.whl
+```
+
+2. 执行如下命令，如果没有报错`No module named 'mindarmour'`，则说明安装成功。
+
+```bash
+python -c 'import mindarmour'
+```
