Information Security-Based Nano- and Bio-Cryptography

Abstract

Information security can provide confidentiality, integrity, and availability for society to benefit efficiently from data storage and open networks. Free space communication networks suffer from adversaries who interfere with data on networked computers. Inventing new protection techniques has arisen to ensure integrity and authenticity of digital information. This chapter introduces Nano and Bio techniques in cryptography to enhance the information security systems. Tasks unfeasible on a classical computer can now be performed by quantum computers, yielding a big impact on online security. Threats of exponentially fast quantum algorithms on business transactions could be overcome by this new technology. Based on biological observations, the exploration of biometric cryptography and authentication to determine individuals' authenticity can be done through numeric measurements. This provides very reliable automated verification and strong protection against biometric system attacks.
