Key Management Service Procedures

Description

The step-by-step definitions of how each key-management operation runs across the ground and spacecraft ends, including the preconditions both sides must meet. Key activation, for instance, moves a pre-loaded key on both endpoints into the active state so it can begin protecting traffic, and it assumes the two ends already hold an identical set of keys to activate.

    SDLS key-management procedures (authenticated OTAR, the key lifecycle, key verification) govern how cryptographic material is changed, raising the bar against unauthorized key replacement; but an adversary holding master-key authority can replace keys through the legitimate process, so it addresses rather than interdicts.
