Abstract
A process for cryptographic key generation and safekeeping is provided. A plurality of key agents are selected, each having a copy of the source code. One copy of the source code is loaded onto a secure computer system and is compared with at least one other copy of the source code to validate the loaded copy of the source code. Master key information and locking key information are generated by executing compiled source code. The master key information is then separated into a plurality of master key shares which are distributed to master key agents such that each master key agent possesses one master key share. The locking key information is separated into a plurality of locking key shares which are distributed to locking key agents such that each locking key agent possesses one locking key share. Then, the plurality of locking key shares and the plurality of master key shares are validated, and the secure computer system is securely shut down.
