    App->>+LicenseFile: 读取license文件
    LicenseFile-->>-App: 返回license数据

    App->>+Validator: Base64解码(license.licenseData)
    Validator-->>-App: 获取原始数据

    App->>+Validator: Base64解码(license.signature)
    Validator-->>-App: 获取签名值

    App->>+Validator: 计算SM3(原始数据)
    Validator-->>-App: 生成待验签摘要

    App->>Validator: 用内置公钥验证签名
    alt 签名有效
        Validator->>Validator: 标记为可信数据
    else 签名无效
        Validator->>App: 立即终止启动
    end

    Validator->>+Validator: 验证有效期:
    Note over Validator: now >= validFrom &&<br/>now <= validTo

    Validator->>+Hardware: 获取设备指纹
    Hardware-->>-Validator: 返回MAC/CPUID等

    Validator->>Validator: 校验硬件信息(可选)

    alt 所有验证通过
        Validator->>App: 允许应用启动
    else 任一失败
        Validator->>App: 终止启动并报错
