HANDOVER BETWEEN OPERATORS OF A COMPUTER

Patentradars sammanfattning

This invention discloses an arrangement and method for transferring operational control of a computer between operators using a secret manager containing three compartments: an integrity compartment (one slot per logical storage partition holding integrity secrets), an identity compartment (two operator-identity slots, the first exclusively for a permanent 'first operator'/manufacturer), and a handover compartment (a single-use handover secret). Handovers between any two business operators must always route through the first operator, enforcing isolation and auditability. The system uses only symmetric algorithms and one-way hash functions, making it quantum-resistant, and supports operation in fully network-isolated environments via removable physical storage media. A factory reset erases all non-first-operator data, restoring the computer to the manufacturer's initial state.
