Phishing is one of the most widely-perpetrated forms of cyber attack, used to gather sensitive information such as credit card numbers, bank account numbers, and user logins and passwords, as well as other information entered via a web site. The authors of A Machine-Learning Approach to Phishing Detetion and Defense have conducted research to demonstrate how a machine learning algorithm can be used as an effective and efficient tool in detecting phishing websites and designating them as information security threats. This methodology can prove useful to a wide variety of businesses and organizations who are seeking solutions to this long-standing threat. A Machine-Learning Approach to Phishing Detetion and Defense also provides information security researchers with a starting point for leveraging the machine algorithm approach as a solution to other information security threats.

In the past decade, the number of wireless devices has grown exponentially. Decades ago, all systems were wired computer systems. Wireless technology was not accessible in mobile and portable devices until in recent years, and has followed a variety of methods for encryption and resource management. The purpose of the research in Optimizing IEE 802.11i Resources and Security Essentials is to determine the issues of the performance in current encryption methods in AES-CCMP in different types of devices and handle it so that an optimized resource usage would be achieved with the required security. Two modes for 802.11i for two different groups of devices is suggested and evaluated with the current encryption method for AES-CCMP to compare the performance. Almost every organization in today's world relies on wireless networks to transmit information, and much of that information should be kept secure. Banking, healthcare, and the military are all vital industries that rely on wireless security for a huge section of their operations. Security experts of today and tomorrow will learn a lot from Optimizing IEE 802.11i Resources and Security Essentials, and it can be used for master level in computer science, information security, wireless network security and cryptography.

The title explain new technique of secured and high capacity optical communication signals generation by using the micro and nano ring resonators. The pulses are known as soliton pulses which are more secured due to having the properties of chaotic and dark soliton signals with ultra short bandwidth. They have high capacity due to the fact that ring resonators are able to generate pulses in the form of solitons in multiples and train form. These pulses generated by ring resonators are suitable in optical communication due to use the compact and integrated rings system, easy to control, flexibility, less loss, application in long distance communication and many other advantages. Using these pulses overcome the problems such as losses during the propagation, long distances, error detection, using many repeaters or amplifiers, undetectable received signals, pulse broadening, overlapping and so on. This book show how to generate soliton pulses using ring resonators in the micro and nano range which can be used in optical communication to improve the transmission technique and quality of received signals in networks such as WiFi and wireless communication.

Nonlinear behavior of light such as chaos can be observed during propagation of a laser beam inside the microring resonator (MRR) systems. This Brief highlights the design of a system of MRRs to generate a series of logic codes. An optical soliton is used to generate an entangled photon. The ultra-short soliton pulses provide the required communication signals to generate a pair of polarization entangled photons required for quantum keys. In the frequency domain, MRRs can be used to generate optical millimetre-wave solitons with a broadband frequency of 0–100 GHz. The soliton signals are multiplexed and modulated with the logic codes to transmit the data via a network system. The soliton carriers play critical roles to transmit the data via an optical communication link and provide many applications in secured optical communications. Therefore, transmission of data information can be performed via a communication network using soliton pulse carriers. A system known as optical multiplexer can be used to increase the channel capacity and security of the signals.

Nowadays big organizations have complex administrative structure with scattered offices to face with serious problems related to key management like financial and security problems that based on symmetric encryption system. This project proposes an efficient solution related to symmetric key crypto system so that with solving this problem the organization can have a secure, affordable, efficient, easier and faster symmetric key crypto system. In symmetric key cryptography with the less key size have more secure in comparison to asymmetric cryptography. Therefore using symmetric key cryptography is more secure and Advantageous. The speed of processing symmetric cryptography is higher than asymmetric cryptography. The purpose of this project is to product the software who all of the employees in the organization can have the secret symmetric key cryptography so that they can communicate to each other with the secret key. However, the security of symmetric key cryptography is higher than asymmetric key cryptography. Among of many algorithm available, key derivations algorithm which used in this project is very important for symmetric cryptosystems because one key can be derived to the others. This Method is chosen by key derivation one-way function and implemented by Delphi programming language. Each organization which uses this implemented method the manager of the organization can generate the secret key for all of the employees and its employees has the symmetric secret key and if the employees need to communicate with each other their request should be sent to the manager. This project has been done in three phases and one of the outcomes of this project is a application which generates random key, according to hierarchy of organization.
