1. A method for providing system security and access based on multi-dimensional location characteristics, comprising: collecting contextual information characterizing a specific location during a first time period utilizing a contextual data collection device (CDCD), wherein the contextual information indicates specific characteristics of the location and is collected at the location, and wherein the contextual information includes range information from a single perspective to at least two key materials located at the specific location, and wherein the contextual information further includes measured effect data acquired using dual frequency measurements of dielectric content of intervening material, wherein the measured effect data is a measured effect of the intervening materials on radio frequency (RF) signals received at the CDCD from a remote RF source; creating a contextual location fingerprint (CLF) based on the collected contextual information, wherein the CLF is a data space of values mapped over specific period of time; collecting new contextual information at a location occupied by a device to be verified during a second time period, wherein the new contextual information includes range information from the single perspective to at least two of the key materials located at the specific location; and comparing the new contextual information to the CLF and authenticating the device when the new contextual information is within predefined parameters of the CLF.
3. A method as recited in claim 1 , further comprising the operation of establishing a token, wherein the token is a private session key.
