1. A system of computing nodes comprising:

  • a first computing node comprising a first secure cryptoprocessor having out-of-band non-volatile first memory that stores a hardware-based first private key that is non-visible to a first operating system (OS) for the first computing node;

    a second computing node comprising a second secure cryptoprocessor having out-of-band non-volatile second memory that stores a hardware-based second private key that is non-visible to a second OS for the second computing node and that corresponds to a second public key; and

    at least one storage medium having instructions stored thereon to cause;

    the first computing node to;

    receive the second public key;

    determine a first session key and encrypt first information with the first session key;

    encrypt the first session key with the second public key;

    bind the encrypted first session key to the encrypted first information; and

    communicate the bound encrypted first session key and encrypted first information to cloud based storage; and

    the second computing node to receive and decrypt the bound encrypted first session key with the second private key, while the second private key is still located within the second cryptoprocessor, and the encrypted first information with the decrypted first session key.
