A CHANNEL ANALYSIS IN NETWORK SECURITY - USING A COVERT APPROACH
Raman Kumar, Harsh Kumar Verma · International Journal on Information Sciences and Computing · 2008
Due to rapid development in the field of communication technologies, security has become the major issue in transformation level data and off-line data.It has further increased the need for online security and authentication for secure information exchange using covert channel and a modified model for data security with data hiding.The objective of this work is to implement a model for network security, using covert channels as a secure environment and covert protocol as a new standard for communication between multi parties but without disclosing the client's details.The most important services to secure communication system are authentication, integrity and confidentiality.In this paper, we also propose a model for construction of secure network computation.Our construction is in the standard model and does not require random oracles.In order to achieve this goal, we introduce a number of new techniques.
