Cryptography in Computer System Security

A Review on Distributed System Security using Elliptic Curve Cryptography

Most of the security architecture uses public key cryptosystems for authentication and to secure the communication that takes place on distributes sites. Now a day’s identity based cryptography and certificate-less public key cryptography are used for enhancing the security. Certificate-less based cryptography has reduced the certificate necessity for key distribution and reducing the problem o...

Enhanced Security System Using Symmetric Encryption and Visual Cryptography

With the rapid development of internet, transfer of data reliably and securely has become one of the challenges. In this paper we have introduced a novel visual cryptographic technique. This method is applicable for both Bitmap Color and Grayscale images. This method uses the concept of Residual Number System (RNS) based on Chinese Remainder Theorem (CRT) for share creation and share stacking o...

Enhancement of Security in Visual Cryptography System using Genetic Algorithm

Visual Cryptography (VC) is a special type of encryption technique where an image or document is encrypted by breaking it down into shares. These shares are then printed on transparencies. Decryption is done by superimposing the shares. Thus one can visually decode the secret image without computation. However, this property makes VC insecure as a third party can easily retrieve the secret info...
