A processing system with a trusted platform module (TPM) that supports the migration of digital keys. For example, when the processing system has the first configuration, the application in the processing system may create the first configuration key as the sub key of the TPM storage root key (SRK). The application can also create a subkey that updates the root user key associated with the update mechanism as the first configuration key. The application can also create a user key as the subkey for the updated root user key. When the processing system has a second configuration, the application can create the second configuration key as the subkey for the SRK. The application can request the migration permission to update the organization. In response to receiving a license from the update mechanism, a sub key that can migrate the root user key for second configuration is applied. Other embodiments are also described, and their rights are requested.
【技术实现步骤摘要】
【技术保护点】
一种用于迁移数字密钥的方法，所述方法包括：在具有第一配置的处理系统中，创建第一配置密钥作为所述处理系统中存储根密钥ＳＲＫ的后代密钥；创建根用户密钥作为所述第一配置密钥的后代密钥，所述根用户密钥包括经确认的可迁移密钥ＣＭＫ；在所述处理系统改变为第二配置之后，创建第二配置密钥作为所述ＳＲＫ的后代密钥；向更新机构发送关于将所述根用户密钥迁移到所述第二配置密钥的许可请求；以及响应于接收到来自所述更新机构的许可，迁移所述根用户密钥为所述第二配置密钥的后代密钥。
