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.

Abstract: Mutual dependency between two devices is established by creating mutual dependency tokens containing stateful information to be stored on the issuing device and the client device. The tokens can be used for both web/application-level authentication and network-level authentication. Tokens for IP or MAC addresses can be created and stored in a modified route table, allowing for the creation of private virtual subnets.

Abstract: An apparatus for treating plant diseases and infestations includes a closed receptacle configured to contain a plant and/or produce, and at least one ultraviolet light source mounted in the receptacle and configured to direct ultraviolet light at the plant. The receptacle is provided with latches and position sensors that prevent the ultraviolet source from being activated if the receptacle is open or is not securely supported on a surface.
