Abstract
Techniques for securing a coverage of a wireless system provided by a stationary or mobile node are disclosed. The node may be provided with at least one encryption key. The key may comprise an encryption function table having therein varying functions, such as time-varying physical layer functions, such as transmit power or beam shape/direction of the node. In accordance with the key, coverage associated with transmissions from the node may be varied.
Claims48
A method of securing coverage of a node, comprising:
- the node accessing a physical layer encryption key;
- and
- the node varying, in accordance with the key, coverage associated with transmissions from the node.
A method for accessing coverage of at least one node, comprising:
- a device transmitting identifier information to the at least one node;
- and
- upon authentication by the at least one node, the device receiving a physical layer encryption key comprising an encryption function table having therein time-varying physical layer functions of nodes of a wireless network.
A node for securing coverage of the node, comprising:
- means for accessing a physical layer encryption key;
- and
- means for varying, in accordance with the physical layer encryption key, coverage associated with transmissions from the node.
A mobile device for accessing coverage of at least one node, comprising:
- means for transmitting identifier information to the at least one node;
- and
- upon authentication of the mobile device, means for receiving a physical layer encryption key comprising an encryption function table having therein time-varying physical layer functions of nodes of a wireless network.
A computer program product, comprising a non-transitory computer-readable medium associated with a node in a wireless network, comprising:
- code for causing at least one processor associated with the node to access a physical layer encryption key;
- and
- code for causing the at least one processor to vary, in accordance with the physical encryption key, coverage associated with transmissions from the node.
A computer program product, comprising a non-transitory computer-readable medium associated with a mobile device in a wireless network, comprising:
- code for causing at least one processor associated with the mobile device to transmit identifier information to at least one node of the wireless network;
- and
- code for causing the at least one processor to, upon authentication of the transmitted identifier information by the at least one node, receive a physical layer encryption key comprising an encryption function table having therein time-varying physical layer functions of nodes of the wireless network.
A node for securing a wireless coverage provided by the node, comprising:
- an encryption module configured to receive a physical layer encryption key;
- and
- a transmitter configured to vary, in accordance with the physical layer encryption key, the wireless coverage associated with transmissions from the node.
A mobile device for accessing coverage of at least one node, comprising:
- a transmitter configured to transmit identifier information to the at least one node;
- and
- a receiver configured to receive, upon authentication by the at least one node, a physical layer encryption key comprising an encryption function table having therein time-varying physical layer functions.
