polarization

What is it?

Polarization describes the orientation of a signal being transmitted from a source to a destination. It is best understood in the field of optical communications. In optical fiber, polarization can be affected by non-uniform characteristics which cause birefringence that delays the propagation of light differently in one orientation over another. This can happen, for instance, when a fiber is extruded in a way that causes the core to be oval, rather than circular in cross section. In the RF world, the same phenomenon occurs when a wireless signal reflects off of a material with a different dielectric constant. In both cases, the altering effects are called polarization mode dispersion.

The amazing thing

Here’s the amazing thing. The polarization mode dispersion is frequency dependent. This means wireless signals are altered differently for different frequencies. So, a signal sent in a band of frequencies, which covers most wireless communications, presents a line segment defining the changing angles for each frequency in the band. Through patented technology, this may be used as a fingerprint for any wireless device.

The impact

With a stable fingerprint for every wireless device, one can protect all fixed wireless devices just by passively looking for the naturally occurring fingerprint in the signal. This can be done at the input of an access point, in parallel with its normal demodulation circuitry. Bu the time the access point has completed demodulating the incoming packet, Endpoint technology has the answer to its authenticity.

What does it replace?

Nothing. The technology may be employed in parallel with existing security mechanisms. For sensors in which there is no security software, Endpoint technology becomes its primary protection. For devices with sophisticated security software, Endpoint technology adds a layer of security that is done in parallel. Endpoint technology adds no latency while providing superior cybersecurity.

Whatever your current access point provides as security is unaffected by the addition of Endpoint technology. Other than the ability gained to authenticate the devices you want to communicate with, the operation is completely hands off.

For artificial intelligence cybersecurity applications, Endpoint technology offers a new data point of information on persistent attempts from an unknown source to access the network. This information is often obscured by the attacker using a known MAC address, password and encryption key learned from sniffing wireless signals. But, no more. Endpoint Security has the solution to this elusive attack.

Peace of mind

Stop chasing the perpetrator! We chase the perpetrator when we rely on software solutions that recognize attacks. We constantly update our databases of known attacks. We write software for the edge devices. But, with software comes vulnerability and when the attacker learns the new vulnerabilities, what do we do? We write more software, continuing the cycle. It is time to get out in front of the perpetrator; stop them from entering the network in the first place. Endpoint technology is the way to do just that.
