| Apache Teaclave (incubating) 0.2.0 发布 |
| </h1> <div class="publish-date-author">March 2, 2021 · Mingshen Sun</div></header> <div itemprop="articleBody" class="content__default"><p><a href="/blog/2021-03-01-announcing-teaclave-0-2-0/">English</a> | <a href="/blog/2021-03-01-announcing-teaclave-0-2-0-cn/">中文</a></p> <p>Apache Teaclave (incubating) 是一个隐私安全计算平台，为隐私数据计算赋能。基于硬 |
| 件安全能力，Teaclave 确保敏感数据在可信域外和离岸场景下安全可控的流通和处理，无 |
| 需担心隐私数据泄露和滥用。 Teaclave 同时支持多方参与的联合计算，打破企业和组织中 |
| 的数据孤岛。Teaclave 于 2019 年由百度捐赠进入 Apache 基金会孵化器。在 2020 年 10 |
| 月发布第一个开源社区版本。</p> <p>Teaclave 使用 Intel SGX， 提供基于硬件隔离、内存加密、远程证实等安全技术保护数据 |
| 隐私计算任务。 Teaclave 平台提供了函数即服务（function-as-a-service）接口，降低 |
| 了使用门槛。平台中也实现了众多内置函数，例如机器学习算法，多方联 合求交，加解密 |
| 计算等等常用功能。更重要的是，开发者还可以使用 Python 自由编写函数来操作隐私数据， |
| 在中平台执行。最后，为了避免内存安全漏洞带来的安全风险，Teaclave 还使用内存安全 |
| 编程语言 Rust 编写。</p> <p>2021 年 3 月 2 日，我们迎来了 Teaclave 第二个社区版本的发布 0.2.0。在这一版本中， |
| 我们重点放在提供更多的内建函数，不同语言的客户端 SDK，更方便的 docker 部署环境， |
| 命令行接口，文档等等。</p> <h2 id="teaclave-0-2-0-亮点介绍"><a href="#teaclave-0-2-0-亮点介绍" class="header-anchor">#</a> Teaclave 0.2.0 亮点介绍</h2> <p>在 0.2.0 中，我们添加了多种语言的客户端 SDK，现在我们提供了 Python、Rust、C、 |
| Swift 四种语言的接口，在 Teaclave Meetup #2 中，我们已经介绍了不同语言 SDK 的组 |
| 织结构和框架。简单来说，我们使用 JSON 序列化/反序列化的方式作为多语言的边界。下 |
| 图描述了这几种语言 SDK 的关系，以及一些事例的接口。</p> <p><img src="/assets/img/teaclave-client-sdks.27efa590.png" alt="Teaclave Client SDKs"></p> <h2 id="teaclave-0-2-0-版本详情"><a href="#teaclave-0-2-0-版本详情" class="header-anchor">#</a> Teaclave 0.2.0 版本详情</h2> <p>详细来讲 0.2.0 包括一下修改以及新功能：</p> <h3 id="functions"><a href="#functions" class="header-anchor">#</a> Functions</h3> <ul><li>增加内置的 PCA (Principal Component Analysis) 函数</li> <li>添加泄漏密码查询内置函数 (#447)</li></ul> <h3 id="sdk"><a href="#sdk" class="header-anchor">#</a> SDK</h3> <ul><li>增加 Rust 客户端 SDK (#455)</li> <li>增加 C 客户端 SDK (#470)</li> <li>增加 Swift 客户端 SDK，也就是 iOS framework</li> <li>修改 SDK 中接口的 CMAC 格式为 byte array</li></ul> <h3 id="docker"><a href="#docker" class="header-anchor">#</a> Docker</h3> <ul><li>增加 <code>teaclave-file-service</code> 容器作为示例程序的远程文件系统 (#446)</li> <li>修复在仿真模式下的 docker compose 文件 (#462)</li></ul> <h3 id="cli"><a href="#cli" class="header-anchor">#</a> CLI</h3> <ul><li>增加 <code>attesation</code> 的子命令，可以展示当前 SGX 平台的远程认证报告</li></ul> <h3 id="文档"><a href="#文档" class="header-anchor">#</a> 文档</h3> <ul><li>增加 codebase 中的文档</li> <li>增加在 Azure Confidential Compute VM 中部署 Teaclave 的文档介绍</li></ul> <h3 id="其他"><a href="#其他" class="header-anchor">#</a> 其他</h3> <ul><li>在 binder 模块中增加 input/output buffer 的检查以及测试</li> <li>使用 Github Action 进行 PR 的编译、测试以及格式检查</li> <li>文档的打磨</li></ul> <h2 id="如何下载"><a href="#如何下载" class="header-anchor">#</a> 如何下载</h2> <p>Teaclave 0.2.0 版本可以在官网下载页面找到（注意验证 PGP 签名和 hash）。</p> <h2 id="快速入门"><a href="#快速入门" class="header-anchor">#</a> 快速入门</h2> <p>如果您想尝试使用 Teaclave，我们提供了一个简单的上手文档（<a href="https://teaclave.apache.org/docs/my-first-function/" rel="noopener noreferrer">https://teaclave.apache.org/docs/my-first-function/</a>）来执行一个打印 hello world 的函数。</p> <p>简单来说，你可以通过以下命令使用 docker 编译 Teaclave：</p> <div class="language- extra-class"><pre class="language-text"><code>$ cd incubator-teaclave |
| $ docker run --rm -v $(pwd):/teaclave -w /teaclave \ |
| -it teaclave/teaclave-build-ubuntu-1804-sgx-2.9.1:latest \ |
| bash -c ". /root/.cargo/env && \ |
| . /opt/sgxsdk/environment && \ |
| mkdir -p build && cd build && \ |
| cmake -DTEST_MODE=ON .. && \ |
| make" |
| </code></pre></div><p>然后使用 <code>docker-compose</code> 在仿真模式下执行 Teaclave 的所有服务：</p> <div class="language- extra-class"><pre class="language-text"><code>$ (cd docker && docker-compose -f docker-compose-ubuntu-1804-sgx-sim-mode.yml up --build) |
| </code></pre></div><p>最后，就可以在 examples 目录下使用 Python 调用 echo 函数打印 "Hello, Teaclave!"：</p> <div class="language- extra-class"><pre class="language-text"><code>$ cd examples/python |
| $ PYTHONPATH=../../sdk/python python3 builtin_echo.py 'Hello, Teaclave!' |
| [+] registering user |
| [+] login |
| [+] registering function |
| [+] creating task |
| [+] approving task |
| [+] invoking task |
| [+] getting result |
| [+] done |
| [+] function return: b'Hello, Teaclave!' |
| </code></pre></div><p>如果你想深入的了解 Teaclave 的内部设计和实现，我们还有更多设计文档、API 文档、代码库文档等你发现。</p></div></article></div> <div class="footer"> |
| Apache Teaclave (incubating) is an effort undergoing incubation at The Apache |
| Software Foundation (ASF), sponsored by the Apache Incubator. |
| Incubation is required of all newly accepted projects until a further review |
| indicates that the infrastructure, communications, and decision making process |
| have stabilized in a manner consistent with other successful ASF projects. While |
| incubation status is not necessarily a reflection of the completeness or |
| stability of the code, it does indicate that the project has yet to be fully |
| endorsed by the ASF. |
