Cognitive Security in Software Define Network Layer

Network Layer Security

INTRODUCTION Modern computer networks are characterized by layered protocol architectures, allowing network designs to accommodate unlimited applications and interconnection techniques. This layered approach allows protocols to become modularized; that is, developed independently and put together with other protocols in such a way as to create one complete protocol. The recognized basis of prot...

Cognitive Radio Network: Security Enhancements

Reference to the latest developments the spectrum shortage problems are because of the wireless communication. For the future networks the most practical, scientific and systematic challenges is the use of licensed or unlicensed wireless networks with opportunistic use of the spectrum with, without and limited rules. Since different wireless networks are using different frequency bands. So ther...

Network Effects in the Security Software Market ∗

The market for security software has witnessed an unprecedented growth in recent years. A closer examination of this market reveals certain idiosyncrasies that are not observed in a traditional software market. For example, it is a highly competitive market involving many vendors. Yet, the market coverage seems relatively low. Prior research has not attempted to explain what makes this market d...

Trust Management and Network Layer Security Protocols

Ipsec – a Network Layer Security Protocol

IP Security originated from conception of IPv6, a proposed extension to IPv4, wherein IP addresses would be expanded from 32 to 128 bits and a heightened level of security at the network layer would be achieved. The latter issue was dropped into the hands of the Internet Engineering Task Force in order for this security protocol to become standardized. During this process, it was discovered tha...
