Claim 13:
14. A proximity based authentication method for communicating an encrypted file from a cloud component to a client device, the method comprising:
associating a gateway with a particular location;
communicatively coupling the gateway to the cloud component, wherein the gateway includes a gateway short-range wireless radio;
establishing, by the gateway, a short-range wireless communication channel with the client device;
communicatively coupling the client device to the cloud component, wherein the client device includes a client device short-range wireless radio;
communicating, by the client device short-range wireless radio over the short-range wireless communication channel, with the gateway when the mobile device is in proximity of the gateway;
receiving, at the client device, a gateway authentication key over the short-range wireless communication channel, in which the client device communicates the gateway authentication key to a cloud component database;
receiving, at the gateway, a client authentication device key over the short-range wireless communication channel, in which the gateway communicates the client authentication device key to the cloud component database;
authenticating, at the cloud component, the particular location of the client device when the cloud component receives the gateway authentication key from the client device;
receiving, at the client device, the gateway authentication key over the short-range wireless communication channel the client device communicates the gateway authentication key to the cloud component database;
generating, by the cloud component, the encrypted file from a data file;
communicating, by the cloud component, the encrypted file to the client device;
generating, by the cloud component, a decryption key material;
communicating, by the cloud component, the decryption key material to the gateway; and
communicating, by the gateway short-range wireless radio, the decryption key material to the client device over the short-range wireless communication channel to enable the client device to decrypt the encrypted file.
