Abstract

A decentralized and/or hybrid decentralized method for secure cryptography key storage referred to as Mutual Dependency Architecture (MDA) includes the steps of encrypting the cryptographic key using an unlock key; encrypting the unlock key using an encryption tool to create an encrypted seed; and storing the encrypted seed; wherein a user must have access to a first storage area in the device and to a second storage area external to the device in order to access the cryptographic key. In one embodiment, the encryption tool is a store key that is stored in unencrypted form in the first storage area, while the encrypted seed is stored in the second storage area. In another embodiment, the encryption tool is a Hardware Security Module (HSM) having an authentication key that is encrypted using a store key and stored in the second storage area, while the encrypted seed and the store key are stored in unencrypted form in the first storage area. The method can be used to build a fully encrypted and permanently secure network and/or internet of devices and/or things, and to exchange messages between devices on the network.
