项目背景

WeDPR

WeDPR是一系列即时可用场景式隐私保护高效解决方案套件和服务(参见WeDPR白皮书),由微众银行区块链团队自主研发。方案致力于解决业务数字化中隐私不“隐”、共享协作不可控等隐私保护风险痛点,消除隐私主体的隐私顾虑和业务创新的合规壁垒,助力基于隐私数据的核心价值互联和新兴商业探索,营造公平、对等、共赢的多方数据协作环境,达成数据价值跨主体融合和数据治理的可控平衡。

WeDPR具备以下特色和优势:

  • 场景式解决方案:已基于具有共性的场景需求,提炼出公开可验证密文账本、多方密文决策、多方密文排名、多方密文计算、多方安全随机数生成、选择性密文披露等高效技术方案框架模板,可应用于支付、供应链金融、跨境金融、投票、选举、榜单、竞拍、招标、摇号、抽检、审计、隐私数据聚合分析、数字化身份、数字化资质凭证、智慧城市、智慧医疗等广泛业务场景。
  • 即时可用:高性能、高易用、跨平台跨语言实现、不依赖中心化可信服务、不依赖可信硬件、支持国密算法标准、隐私效果公开可验证,5分钟一键构建示例应用。
  • 透明可控:隐私控制回归属主,杜绝数据未授权使用,在『数据可用而不可见』的基础上,进一步实现数据使用全程可监管、可追溯、可验证。

WeDPR全面拥抱开放,将陆续开源一系列核心算法组件,进一步提升系统安全性的透明度,提供更透明、更可信的隐私保护效果。WeDPR-Lab就是这一系列开源的核心算法组件的集合。

WeDPR-Lab-Core v1.5.0版本开源主要内容如下:

  • 多方密文决策ACV核心算法,支持全密文决策、全流程可验证的多方隐私决策。

  • ACV场景式解决方案的一个交互式样例,实现以下主要功能:

    • 密文空白选票的颁发

    • 决策密文选票的生成

    • 密文决策过程的零知识证明生成与验证

    • 密文决策结果的汇总

    • 汇总过程的零知识证明生成和验证

    • 决策结果的验证

  • Rust SDK,封装底层算法,提供易用、易扩展、跨语言的编程接口;

  • 其他基础工具代码。

WeDPR-Lab-Core v1.4.0版本开源主要内容如下:

  • 将WeDPR-Lab Crypto v1.1.0新增的零知识证明的聚合验证算法运用于VCL公开可验证密文账本。

  • 聚合验证算法在VCL中应用后的具体效果是:

对于多组密文记录及其加和关系证明(或乘积关系证明),无需针对每个加和证明(或乘积证明)分别进行验证,而只需执行一次聚合验证,就可对所有加和证明(或乘积证明)进行验证。

聚合验证算法通过减少开销较大的椭圆曲线点运算的个数,将VCL中对应零知识证明批量验证的效率提升了近60%。

WeDPR-Lab-Core v1.3.0版本开源主要内容如下:

  • 密钥生成及管理的核心算法,包括:

    • 密钥助记词的生成

    • 基于助记词的密钥生成

    • 基于分层结构的密钥派生

  • Rust SDK,封装底层算法,提供易用、易扩展、跨语言的编程接口;

  • FFI接口,支持交叉编译跨语言、跨平台所调用的FFI适配接口;

  • 其他基础工具代码。

WeDPR-Lab-Core v1.2.0版本开源主要内容如下:

  • 选择性认证披露SCD核心算法,支持多种断言证明的高效稳定实现;

  • SCD场景式解决方案的一个交互式样例,实现以下主要功能:

    • 选择性披露证书颁发

    • 零知识断言披露证明

    • 零知识断言披露验证

    • 选择性属性明文披露和验证

  • Rust SDK,封装底层算法,提供易用、易扩展、跨语言的编程接口;

  • FFI接口,支持交叉编译跨语言、跨平台所调用的FFI适配接口;

  • 其他基础工具代码。

WeDPR-Lab-Core v1.1.0版本开源主要内容如下:

提供更为丰富的密码学算法组件,具体包括:

  • 密码算法组件

    • 签名验证

    • 哈希算法

    • 公钥加解密ECIES

  • FFI接口,新增支持交叉编译、跨语言、跨平台所调用的FFI适配接口。

WeDPR-Lab-Core v1.0.0版本开源主要内容如下:

  • 公开可验证密文账本VCL的一个交互式样例,实现以下主要功能:

    • 密文金额发行

    • 密文金额四则运算关系验证

    • 密文金额范围验证

  • 三类零知识证明算法的高效稳定实现,包括

    • 密文加和关系证明

    • 密文乘积关系证明

    • 密文范围证明

  • Rust SDK,封装底层算法,提供易用、易扩展、跨语言的编程接口;

  • FFI接口,支持交叉编译跨语言、跨平台所调用的FFI适配接口;

  • 其他基础工具代码。

我们期望能够通过代码开源的方式:

  • 有效降低使用隐私保护算法组件的技术门槛;
  • 减少业务系统集成隐私保护特性的开发成本;
  • 助力全行业伙伴安全、合规地开展数据业务。

欢迎社区伙伴参与WeDPR-Lab的共建,一起为可信开放数字新生态的构建打造坚实、可靠的技术底座。

安装

安装Rust环境

安装nightly版本的Rust开发环境,可参考Rust官方文档

下载WeDPR-Lab源代码

使用git命令行工具,执行如下命令。

git clone https://github.com/WeBankBlockchain/WeDPR-Lab-Core.git

接口文档

生成并查看Rust SDK接口文档

在本项目的根目录(即WeDPR-Lab-Core目录)中,运行如下命令。

cargo doc --no-deps

以上命令将根据代码中的注释,在target/doc子目录中,生成的SDK接口文档。

进入target/doc文档目录后,会看到所有SDK相关的包名(包含WeDPR-Lab和其他依赖包),进入其中任意一个包名的目录,用网页浏览器打开其中的index.html文件,便可查看WeDPR-Lab相关的接口说明。
