A primary platform (PP) can (i) support a first set of cryptographic parameters and (ii) securely download an unconfigured secondary platform bundle (SPB) that includes a configuration package (SPB CP). The SPB CP can establish a secure session with a configuration server (CS). The CS can select operating cryptographic parameters supported by the first set. The SPB CP can derive an SPB private and public key. The PP can use the selected operating cryptographic parameters to securely authenticate and sign the SPB public key. The CS can (i) verify the PP signature for the SPB public key and (ii) generate an SPB identity and certificate for the SPB and (iii) send the certificate and SPB configuration data to the SPB CP. The SPB CP can complete configuration of the SPB using the SPB identity, certificate, and configuration data. The configured SPB can authenticate with a network using the certificate.
