Abstract
At least one embodiment takes the form of a process carried out by a key-management infrastructure (KMI). The KMI receives first and second disassembly products of a high-security cryptographic key and provides the first and second disassembly products to a mobile radio for reassembly of the high-security cryptographic key. Providing the first disassembly product to the mobile radio includes providing the first disassembly product to the mobile radio over a local connection via a restricted-access key variable loader. Providing the second disassembly product to the mobile radio includes (i) generating a medium-security-encrypted second disassembly product at least in part by encrypting the second disassembly product based on at least one medium-security cryptographic key, and (ii) providing the medium-security-encrypted second disassembly product to the mobile radio over an air interface.
