Randomness lays the foundation for information security. Quantum random number generation based on various quantum principles has been proposed to provide true randomness in the last two decades. We integrate four different types of quantum random number generators on the Alibaba Cloud servers to enhance cybersecurity. Post-processing modules are integrated into the quantum platform to extract true random numbers. We employ improved authentication protocols where original pseudo-random numbers are replaced with quantum ones. Users from the Alibaba Cloud, such as Ant Financial and Smart Access Gateway, request random numbers from the quantum platform for various cryptographic tasks. For cloud services demanding the highest security, such as Alipay at Ant Financial, we combine the random numbers from four quantum devices by XOR the outputs to enhance practical security. The quantum platform has been continuously run for more than a year.

随机性是信息安全的基础。在过去的二十年中，已经提出了基于各种量子原理的量子随机数生成以提供真正的随机性。我们在阿里云服务器上集成了四种不同类型的量子随机数生成器，以增强网络安全。后处理模块集成到量子平台中以提取真正的随机数。我们采用改进的身份验证协议，其中原始伪随机数被量子数替换。来自阿里云的用户，例如蚂蚁金服和智能接入网关，从量子平台请求随机数来执行各种加密任务。对于安全性要求最高的云服务，比如蚂蚁金服的支付宝，我们通过对输出进行异或来组合来自四个量子设备的随机数以增强实际安全性。量子平台已经连续运行了一年多。
