BLOCKCHAIN BASED ACCESS TO DEVICES ON A NETWORK WITH LOCAL TOKEN ACQUISITION
An access control method and system that uses tokens on a blockchain which are used for subsequent access to a local network. The tokens are authenticated on the local network using blockchain. A client device can present a token to the local network from anywhere in the world in order to access at least one device on the local network. In an example, the method includes presenting, to a node of the local network, the token; and receiving, from the node, successful authentication of the token. The method can include, after the successful authentication of the token, authorizing the client device to access a device on the local network or removing access to the device for the client device.
