Abstract
A method of remotely initializing at least one device is disclosed. The method includes initializing at a local host a cryptographic authorization sequence after receiving a secure input value. The method further includes receiving at a local host cryptographic controller a first authorization request from a first remote device. After a challenge-response authentication protocol, the first remote device is authenticated and receives a public key infrastructure certificate. The method includes receiving at a first remote cryptographic controller a second request from a second remote device. After a challenge-response authentication protocol, the first remote device is authenticated, but does not receive a public key infrastructure certificate. A system for remotely initiating at least one device is also disclosed.
