Hybrid Security Mechanism to Enhance the Security and Performance of IoT System

Research has centred on the security of IoT system by orchestrating cryptography, packet filtering, user defined port and packet compression mechanism. It has been espied that there have been numerous researches that have posed security by making use of cryptography approach. But this approach is not checking the intruders or unauthentic data transmission. It only safeguards the data from getting into wrong hands. It makes data non comprehensible for unauthorized person but could not protect it from being ruined or altered. On other hand packet filtering and IP filtering has deterred such intruders but cryptography was overlooked. Some researchers did integrate aforementioned approaches but the overall performance was degraded. One of the major reasons for the reduction of performance is that a lot of time is consumed in transmission of data when cryptographic and packet filtering operations are performed together. Thus, the proposed research is making use of packet compression technique along with packet filter and cryptographic approach. Moreover, adding an extra layer of security, the proposed work made use of user defined ports because predefined ports might be accountable for unsecure transmissions.
