Security andNetworkPerformance Evaluation ofKK'Cryptographic Technique inMobile AdhocNetworks

Inthispaper,we analyze theperformance,iswithout fixed boundaries. Asaresult, theboundary that security andattack aspects ofcryptographic techniquesseparates theinside network fromtheoutside worldbecomes andalsoinvestigate theperformance-security tradeoff for blurred. A malicious attacker canreadily becomearouter and mobileadhocnetworks. We propose KK' cryptographic disrupt network operations byintentionally disobeying the technique andanalyze thedominantissues ofsecurity,protocol specifications (11).Mainly, thedifficulties of attack andvarious information theorycharacteristics of dealing withsecurity issues inanadhocnetwork comefrom cipher textsforDES,Substitution andproposed KK' thekeymanagement andtrust relationship management. cryptographic technique.
