Intrusion Detection System based on Ant
Challenge of designing and building of the current Network Intrusion Detection System not only improves the ability for discriminating the improper internet behaviors, but also considers the plenty of computer resources which will be cost during the analysis of the network packets and behaviors. During the establishment of a fast intrusion detection system, the major purpose of the research is to intensify the data handling capacity when the network management system faces the mass network behavior. In the research, the modules stored in the network packets of the intrusion detection system are analyzed, and then the network flow data by applying the clustering algorithm based on the ant colony system is classified. Finally, a kind of algorithm which can remove repetitive computation is designed so that the flow can accelerated and the velocity can be distinguished. Experimental results show that the proposed fast clustering algorithm can significantly reduce the original computation time while sacrificing or promoting a very small accuracy, and then the computation speed of the intrusion detection system can be accelerated.
Comparative Study of Symmetric Key Algorithms-Des, AES and Blowfish
This paper presents a peer analysis in the field of encryption algorithms, concentrating on private key block ciphers which are generally used for bulk data and link encryption. We have initially surveyed some of the popular and efficient algorithms currently in use. This paper focuses mainly on the different kinds of encryption techniques that are existing, and comparative study together as a literature survey. This study extends to the performance parameters used in encryption processes and analyzing on their security issues. Cryptography is the practice and study of hiding information. Prior to the modern age, cryptography was almost synonymous with encryption i.e. the conversion of information from a readable state to unreadable state. In order to avoid unwanted persons being able to read the information, senders retain the ability to decrypt the information. There are three types of Cryptography. They are Asymmetric-key cryptography, symmetric key cryptography and hashing. Encryption methods in which both the sender and receiver share the same key are referred to as symmetric key cryptography. This paper provides a comparison between symmetric key algorithms such as DES, AES, and Blowfish. The comparison is made on the basis of these parameters such as block size and key size.
Analysis of Routing Algorithms based on the Natural Inspiration
Nature is a great and immense source of inspiration for solving hard and complex problems in computer science since it exhibits extremely diverse, dynamic, robust, complex and fascinating phenomenon. Nature inspired algorithms are metaheuristics that mimics the nature for solving optimisation problems opening a new era in computation. A new agent-based routing algorithm using optimisation techniques is implemented in this paper. The different optimisation techniques are warty frog fish, artificial ant, ant, ant lion, grey wolf, genetic algorithm (GA) are the combinations used in the packet delivery between the networks. The routing is a process of carrying the data from source to destination in the network. The output of these algorithms is determined by the simulation time. The experiments are implemented with the NS2 software platform, which is based on the basics of C, C++ and TCL scripting language. The results of the algorithm showed that the grey wolf optimiser (GWO) is much better than the other algorithms in the packet delivery between the networks.
