Enhancing Security with Nanotechnology

Nanotechnology is useful not only for harnessing physical techniques in security applications but also to help researchers use physics theories to prove applications' security strength. Security strength depends on an adversary's inability to perform an operation that valid users can easily perform. Nanotechnology can help resolve the challenge of devising a means to execute this principle and accurately evaluate the adversary's limitations. The idea of enlisting physics theories to devise security applications and prove their strength isn't new. For example, quantum cryptography - which many consider as a revolutionary information security technology -facilitates secure ways to exchange secret keys. Theories from physics, not mathematics, provide the foundation to implement the application and prove its security strength
