In this book, research work in symmetric domain of cryptography is preferred over asymmetric cryptography domain at FPGA PLATFORM. To minimize the attacks like brute force attacks, linear and differential attacks over the system or the network, the approach adopted in this research work, verifies and conforms the increased level of security in comparison to previous approaches and also keeping in mind the resource consumption. The idea behind is to achieve "OPTIMIZATION" simultaneously increasing the security so that it can be used in different domains whether being at the network,...

Biometrics is the most widely used area which helps in identifying a person via his behavioral and physiological properties. The most matured and accepted biometric system is the fingerprint recognition system. It has been proved that fingerprint is the most accurate biometric trait as compared to other traits. Fingerprint contains complex patterns of stripes, called ridges. There exists some gap between the ridges, called valleys. The pattern is unique for a particular finger. Even two fingers of a same person have different patterns. In fingerprint matching system, we compare these patterns...
