NCP Network Crypto Protocol(Implementation).

Abstract

There has always been ·a lot of mystique- and media hype surrounding cryptography. In distributed systems, objects are scattered to different places. This makes the security issues more difficult. Another problematic field in distributed systems security is authentication . The decision that should be made is whether the security should be enforced centrally or locally . In centralized security enforcement, there could be some kind of Key Distribution Center (KDC), where the keys of all the devices are stored . The Key Distribution Center acts as a Trusted Third Party (TTP) that users can use to authenticate themselves and other users, and to get secure connections everywhere In the network. There could be a trusted Certification Authority (CA), which issues key certificates and a Certification Distribution Center (CDC), which stores all the certificates issued by the Certification Authority. Our aim is to design and develop Symmetric Cryptographic system with KDC and CA Server
