Network Security Approaches in Distributed Environment

What is it about?

Distributed computing is one of the thrust areas in the field of computer science, but when we are concerned about security a question arises, “Can it be secure?” From this note, the authors start this chapter. In the distributed environment, when the system is connected to a network, and the operating system firewall is active, it will take care of all the authentication and access control requests. There are several traditional cryptographic approaches which implement authentication and access control. The encryption algorithms such as Rijndael, RSA, A3, and A5 is used for providing data secrecy. Some of the key distribution techniques have been discussed such as Diffie Hellman key exchange for symmetric key, and random key generation (LCG) technique is used in red-black tree traversal which provides the security of the digital contents. The chapter deals with the advanced versions of the network security techniques and cryptographic algorithms for the security of multimedia contents over the internet.
