Classification: CPC H  G | IPC G  H

Claim 17:
18. A system comprising:
a processor circuitry; and
a memory circuitry to communicate with the processor circuitry, the memory circuitry comprising instructions to delay production code signing for a heterogeneous artifacts of a pre-production version of a software package by directing the processor circuitry to:
generate a transient code signing key pair (TKP) and a transient intermediate code CA key pair (CKP);
issue a transient code signing CA Certificate for the TKP (TCACert), wherein the TCACert is signed with a CKPPriv;
sign each code artifact in a signing session with a TKPpriv;
embed a TCAcert in the software package;
approve production release of a production version of the software package;
delay-issue a CKPcert by using a product root CA public key; and
publish a CKPcert at a pre-defined location pointed-to by TCAcert embedding.
