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
