Nanotechnology is concerned with materials and systems whose structures and components exhibit novel and significantly improved properties. These physical, chemical, and biological properties, processes and phenomena are novel due to their nanoscale size in the range of about 10-9 to 10-7 m (1,000 times smaller than the diameter of human hair). The aim is to exploit these properties by gaining control of structures and devices at atomic, molecular, and supra-molecular levels and to learn to efficiently manufacture and use these devices. New behavior at the nanoscale is not necessarily as predictable as observed at large size scales. The most important changes in behavior are caused not by the order of magnitude size reduction, but by newly observed phenomena intrinsic to the nanoscale, such as size confinement, predominance of interfacial phenomena and quantum mechanics.

Several cryptographic algorithms were implemented using the public library Lib-Tom-Crypt and benchmarked on an ARM7-processor platform. The common coding schemes in use were ECC and RSA (asymmetric coding schemes), AES, 3DES and two fish (symmetric algorithms). The benchmark considered both code size and speed of the algorithms. The two asymmetric algorithms, ECC and RSA, are possible to be used in an ARM7 based access system. Although, both technologies can be configured to finish the calculations within a reasonable time-frame of 10 Sec.
