Location-Enabled Security Services in Wireless Network
First Claim
1. A method of providing location enabled security services in a wireless network, said method comprising the steps of:
- receiving a network access request from a node requesting access to said wireless network;
calculating a probability level for a position for said requesting node using position information claimed by said requesting node and position information about said requesting node derived from signal measurements for said requesting node received by at least one existing authorised node in said wireless network; and
denying access for said requesting node to said wireless network if said probability level does not satisfy a specified threshold condition for network security.

Abstract
A method (300), an apparatus (100), and a computer program product for providing location enabled security services in a wireless network are disclosed. In the method, a network access request from a node requesting access to the wireless network is received (304). A probability level for a position for the requesting node is calculated (310) using position information claimed by the requesting node and position information about the requesting node derived from signal measurements for the requesting node received by at least one existing authorised node in the wireless network. Access for the requesting node to the wireless network is denied (314) if the probability level does not satisfy a specified threshold condition for network security (312). Access for the requesting node to the wireless network is granted (318) if the probability level does satisfy the specified threshold condition (312).

17. A method of determining a secure routing path through a wireless network, said method comprising the steps of:
-
determining local propagation parameters; determining either a standard error ellipse or a nuisance error ellipse at a claimed position of a node requesting access said wireless network; granting said requesting node and all existing authorised nodes of said wireless network broadcast privileges if a probability level for a position for said requesting node dependent on the error ellipse satisfies a specified threshold condition, said probability level calculated using claimed position information provided by said requesting node and position information about said requesting node derived from signal measurements for said requesting node received by at least one existing authorised node in said wireless network; and denying broadcast privileges to said requesting node and at least one existing authorized node within a hearing ellipse relative to said requesting node if said probability level for said position for said requesting node fails to satisfy said specified threshold condition. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
