Abstract
The present disclosure is directed to a system and method for remotely initializing at least one device in communication with a local host device utilizing an asymmetric cryptographic authorization scheme. According to various embodiments, at least one remote device sends an authorization request including a random value to the local host device. The local host device returns an approval response to the remote device, where the approval response includes the random value encoded utilizing a private key. The remote device is then initialized (e.g. powered on or placed in an active state) upon verification of the encoded random value utilizing a public key that is paired with the private key.
