Implementation of security model in cognitive networks

摘要

The paper will describe various types of security issues which include confidentiality, integrity and availability of data. There exists various threats to security issues traffic analysis, snooping, spoofing, denial of service attack etc. This paper focuses on symmetric and asymmetric cryptography. A new model is proposed RES(Requirement Encryption Standard) which combines various security parameters. There exists various security models in modern cryptography. However there still exists various security threats. RES is a new proposed model which overcomes various security active and passive attacks.
