Abstract

An embodiment of the invention allows a user to back-up/store data to a cloud-based storage system and synchronize that data on the user's devices coupled to the storage system. The devices have secure out-of-band cryptoprocessors that conceal a private key. The private key corresponds to a public key that is used to encrypt a session key and information, both of which are passed to and through cloud based storage, all while remaining encrypted. The encrypted material is communicated from the cloud to another of the user's devices where the encrypted material is decrypted within a secure out-of-band cryptoprocessor (using the private key that corresponds to the aforementioned public key) located within the device. The embodiment allows for secure provisioning of the private key to the devices. The private key is only decrypted within the cryptoprocessor so the private key is not “in the open”. Other embodiments are described herein.
