Analysis of Different Cryptosystems Using Meta-heuristic Techniques

چکیده
With the increasing usage of internet, the need of securing the information is also getting more important. The most widely used technique to make the information secure is cryptography. Cryptanalysis is a method to break the unreadable cipher text without having the key. This paper describes a method of deciphering encrypted messages of Vigenere cipher cryptosystems, Simple substitution cryptosystems and LFSR based cryptosystems by some nature inspired meta-heuristic techniques like swarm intelligence and evolutionary techniques.

A Comparison between Different Meta-Heuristic Techniques in Power Allocation for Physical Layer Security
Node cooperation can protect wireless networks from eavesdropping by using the physical characteristics of wireless channels rather than cryptographic methods. Allocating the proper amount of power to cooperative nodes is a challenging task. In this paper, we use three cooperative nodes, one as relay to increase throughput at the destination and two friendly jammers to degrade eavesdropper&rsqu...

In this study, given the sequence dependent setup times, we attempt using the technique of Response Surface Methodology (RSM) to set the parameters of the genetic algorithm (GA), which is used to optimize the scheduling problem of n job on 1 machine (n/1). It aims at finding the most suitable parameters for increasing the efficiency of the proposed algorithm. At first, a central composite d...
متن کاملApplication of Particle Swarm Optimization and Genetic Algorithm Techniques to Solve Bi-level Congestion Pricing Problems
The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...
متن کاملOptimizing the warranty period by cuckoo meta-heuristic algorithm in heterogeneous customers’ population
Warranty is now an integral part of each product. Since its length is directly related to the cost of production, it should be set in such a way that it would maximize revenue generation and customers’ satisfaction. Furthermore, based on the behavior of customers, it is assumed that increasing the warranty period to earn the trust of more customers leads to more sales until the market is sat...
