Abstract: Disclosed is a method for providing a public key for authenticating an integrated circuit. In the method, the integrated circuit obtains a hardware key and an integrated circuit identifier. The integrated circuit generates a derived key based on the hardware key using a key derivation function (KDF) shared with a manufacturing machine. The integrated circuit generates a private key and a corresponding public key using the derived key as an input to a deterministic function. The integrated circuit then provides the public key and the integrated circuit identifier to a partner service for authentication of the integrated circuit using an anonymized credential database to be provided to the partner service by a manufacturer.

Abstract translation: 公开了一种用于提供用于认证集成电路的公钥的方法。 在该方法中，集成电路获得硬件密钥和集成电路标识符。 集成电路使用与制造机器共享的密钥导出功能（KDF），基于硬件密钥生成派生密钥。 集成电路使用派生密钥作为确定性函数的输入生成私钥和相应的公钥。 然后，集成电路将公钥和集成电路标识符提供给合作伙伴服务，以便使用由制造商提供给合作伙伴服务的匿名凭证数据库来对集成电路进行认证。
