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 k i n d o f Key. D i s tr i bu t i on C en t er ( K D C) , w h e re the e key s o f a 11 the e 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
