Noise-Based Physical Layer Encryption
Introduction AlphaEta™ Encryption:
| AlphaEta™ is a novel method of encryption that utilizes quantum noise to augment the security of the best state-of-the-art cryptographic algorithms. In AlphaEta™ true noise acts to further “scramble” the signal in an unpredictable way which enhances the normally deterministic pseudo-random scrambling of traditional cryptography systems. Despite the use of such advanced techniques, the systems remain practical and can be integrated into traditional communication networks. |

Our systems make use of fundamental, and thus unavoidable, noise called quantum noise. Quantum noise is not normally a factor in radio-frequency communications such as cell phones, but does comes into play at optical frequencies. Our high-speed encrypted optical communication systems automatically force this noise to interfere with an eavesdropper’s observation in such a way as to make the job of attacking the secure channel much more difficult. AlphaEta encrypts optical signals directly at the physical layer- manipulating the raw optically transmitted bits. This adds a new, and qualitatively different, layer of security to optical communication systems.
While low speed randomization, such as the use of random number generators, are often used in cryptographic algorithms for security purposes, NuCrypt exploits optical noise to automatically provide high speed randomization of every single data bit. Our systems use commercially available off-the-shelf components and are compatible with current optical infrastructure, such as dense wavelength division multiplexing (DWDM). They allow for ultrahigh secure optical encryption which can protect data transmitted at very high rates over long distances. This makes our AlphaEta™ encryption method the first practical physics based ultrahigh security encryption system available. Note that in addition to our optical systems, we have also engineered ultra-secure radio-frequency transceivers by incorporating a small quantum noise source into the transmitter. The ease with which AlphaEta can be brought into the RF domain clearly demonstrates the flexibility and practicality of the technology.
