Abstract

本申请实施例涉及芯片安全技术领域，公开了一种密钥生成方法、获取方法、私钥更新方法、芯片和服务器。密钥生成方法，应用于芯片，芯片存储有内部密钥，包括以下步骤：获取第一随机数与第二随机数(101)；根据第一随机数与所述内部密钥生成芯片的初始私钥，并根据第二随机数与内部密钥生成芯片的更新私钥(102)；根据初始私钥生成与初始私钥对应的初始公钥，并根据更新私钥生成与更新私钥对应的更新公钥(103)；将初始公钥、更新公钥和第二随机数发送至服务器(104)，供服务器在接收到芯片的私钥更新请求时，将第二随机数发送至芯片，触发芯片的私钥更新，使得对芯片的私钥进行更新时，节省了较多的人力物力，更加安全可靠。
