Webcryptography schemes can be studied, to a large extent, by suitable geometric models, belonging to the important field of finite geometries. This book provides an update survey of the state of the art of finite geometries and their applications to channel coding against noise and deliberate tampering. The book is divided into two sections,
WebVisual Cryptography (VC) is a powerful technique that combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares that are able to be stacked together so as to approximately recover the original image. VC is a unique technique in the sense that the encrypted message can … WebDES is a block cipher, which divides the plain text into 64-bit blocks and encrypts each block. The basic concept is as follows: At the time DES was released, it was a marvelous invention. Even today the algorithm is still sound. However, the small key size, 56 bits, is not good enough to defend against brute-force attacks with modern computers.

The history of cryptography began thousands of years ago. Cryptography uses a variety of different types of encryption. Earlier algorithms were performed by hand and are substantially different from modern algorithms, which are generally executed by a machine. Historical pen and paper ciphers used in the past are sometimes known as classical ciphers. They include:
