摘要： A method for securely exchanging public key certificates in an electronic device (400) using a single or dual level of public key includes obtaining a replacement public key certificate (401) to replace an original public key certificate. The replacement public key certificate is signed (403) using the private key of the original public key certificate. The signature of the original public key certificate is validated (407) and the replacement public key certificate is written to memory where the original public key certificate cannot again be used as a default. Thus, the method of the invention uses either a single signature or combination of double signatures to permit transfer of signing authority to an independent third party. Once the original secondary public key is overwritten, the manufacturer's original secondary public key may no longer be used and the process is irreversible.
摘要翻译：一种使用单级或双级公开密钥在电子设备（400）中安全地交换公共密钥证书的方法包括：获取替换公开密钥证书（401）以替换原始公共密钥证书。使用原始公钥证书的私钥对替换公钥证书进行签名（403）。原始公共密钥证书的签名被验证（407），替换公钥证书被写入到原始公开密钥证书不能被再次用作默认的存储器中。因此，本发明的方法使用单个签名或双重签名的组合来允许将签名授权转移给独立的第三方。一旦原始的二级公钥被覆盖，制造商的原始二级公钥可能不再被使用，并且该过程是不可逆转的。
