Huckleberry Finn - Escape From a Cruel and Oppressive Society America... land of the free and home of the brave; the utopian society which every European citizen desired to be a part of in the 18th and 19th centuries. The revolutionary ideas of The Age of Enlightenment such as democracy and universal male suffrage were finally becoming a reality to the philosophers and scholars that so elegantly dreamt of them. America was a playground for the ideas of these enlightened men. To Europeans, and the world for that matter, America had become a kind of mirage, an idealistic version of society, a place of open opportunities. Where else on earth could a man like J. D. Rockefeller rise from the streets to become one of the richest men of†¦show more content†¦Too precious and dear to let go, the South held on to this institution until the Thirteenth Amendment was signed in by Lincoln in 1865. In this hypocritical society is where The Adventures of Huckleberry Finn finds itself. Mark Twains The Adventures of Huckleberry Finn is an epic story of the journey of a redneck boy and a runaway slave, escaping the grips of society in the hope of a chance at the freedom they long for so dearly. The novels author, Mark Twain, also grew up in this society. Samuel Clemens, Twains birth name, led a life that had a great influence on the works that he produced later in his life. Born in Florida, Missouri, Clemens childhood was filled with adventures much like those found in both The Adventures of Tom Sawyer and The Adventures of Huckleberry Finn. Following his childhood experiences, Clemens worked on steamboats on the Mississippi River up until the river was closed during the Civil War. The war opened his eyes to the issue of slavery, which shows up in many of his works, including Huckleberry Finn. Huckleberry Finn takes place when slavery was very much a part of Southern culture and society, nearly thirty years prior to the Civil War. Since the institution of slavery was such a stronghold of Southern society during Huckleberry Finn, Hucks helping bring Jim to freedom makes him an outlaw.

Wimax Networks for Data Encryption Standard -myassignmenthelp

Question: Discuss about theWimax Networks for Data Encryption Standard. Answer: Introduction: WiMAX or Worldwide Interoperability for Microwave Access is a coalition of the wireless industry for the advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks. WiMAX (Pareit et al., 2012) is commonly known as 4G network and is a wireless wide area network (WAN) that can cover the area same as DSL lines but without wires. 3DES (Data Encryption Standard) (Singh, 2013) and AES (Advanced encryption standard) (Ahmad Ismail, 2016) is used by WiMAX to encrypt the data transferred on the network. The 3DES uses three different keys to encrypt the data. Each data is of the length of 56-bits each. In some softwares the performance becomes slow due to the use of this three keys. The 3DES is becoming obsolete due to its slow performance and the limit of length of the keys. Advanced Encryption Standard (Rewagad Pawar, 2013) is the main tool used for encryption in WiMAX technology. Encryption key of 128-bit, 192-bit and 256-bit is supported by the advanced encryption s tandard. AES is a popular algorithm which was built from CCMP. 3DES is much slower than AES. Advanced Encryption standard is much more easy to implement and a very little memory is used. However, AES does not require dedicated processors on board the BS, and m their might be a risk of not being used by all end-user terminals. Initially this helps in considering the fact that 3DES still remains a vital encryption tool on the WiMAX (Dadhich, Narang Yadav 2012) network in spite of the presence of advanced encryption standard. Disadvantages of WAPN technology: The most common WAPN technology are the Bluetooth and the ZigBee network. Both this technology faces the same difficulty as that of the security issues faced by the wireless technology. Problems faced by Bluetooth technology are listed below: Eavesdropping This is a process by which an attacker can sniff into the air of Bluetooth transmission and exploit the right vulnerabilities, read or listen to the data(Saliou et al.).That means someone is conversing using a Bluetooth headset then someone can potentially listen to it. Bluesnarfing This is a process in which an attacker can pair to a device and once devices are paired, access and steal information from the Bluetooth device becomes very easy. The pairing is usually done without the knowledge of the user, which possiblyresults in stolen contact information, photos, videos, calendar events, and more(Ketari Khanum, 2012). Blue bugging- An attacker caneasily remote control the various aspects of the users device. Sending of outgoing calls and texts, forwarding of incoming calls and texts, change of settings, and watching of screens and keypresses and many other things(Rawat Bhattacharya, 2016). Denial of servicein this process an attacker can put unwanted stuffs in the users device, block the communications, drain the battery of the device, or even crashes the device. Problems faced by ZigBee technology: Sniffing: there are many networks which do not use proper encryption as a result the attackers take advantage to sniff all the communications with the proper use equipments. in this attack all the information from a network is collected, which is possible in a network which implements the standard generic security level protocols for communication(Olawumi et al., 2014). Replay attack: This type of attack is a key based attack where the attacker records the approved traffic on a network and paly it later which causes a malicious effect. This attacks are straight forward for ZigBees which do not implement a do not implement any encryption for the communication(Vidgren et al., 2013). Physical Attacks: this type of attacks are most common and involves the tampering of ZigBee devices by locating it. Hard coded encryption keys which are loaded in the RAM are often employed by radios operating in the ZigBee network once the device is powered.as the devices in the network are disturbed and flashed so there remains a possibility of replacing the keys becomes less and having known the issues the attackers can set up special serial interfaces in order to intercept the encryption key in the ZigBee device when the power rises from flash to RAM(Ramsey, Mullins White, 2012). Denial of Service-There are many other methods along with the one mentioned above thereby making ZigBee network unsafe. Signal jamming, reflexive jamming, maximization of frame counter are some other problems faced by the network(Bahl, Sharma Verma, 2012). Energy Harvesting Faisal Karim, and Sherali Zeadally. "Energy harvesting in wireless sensor networks: A comprehensive review." Renewable and Sustainable Energy Reviews 55 (2016): 1041-1054. This article discusses about the energy harvesting techniques used in daily lives. Energy harvesting is one of the emerging technology related to applications on indoor and outdoor environment. The demands for energy harvesting as increasing with the advancement of microelectronics and MEMS. This rep article also discusses about the problems and applications of energy harvesting. This has gained the attention of various stallholders which involves designs and implementation of this technology to face the energy demands of future wireless sensor networks. Moreover, this article focuses on the techniques required to meet the future energy demands of the WSNs. Specifically, this focuses on the classifications of the schemes used on energy harvesting techniques in WSNs. The article has thoroughly reviewed the classes and sub classes of energy harvesting techniques and the harvester mechanism along with the efficiency of the harvester. For each category the harvester hardware system has d ifferent design and has different harvesting capabilities. The different designs of the harvester determine the efficiency of the harvester. A survey has been conducted on various models aimed to predict the future energy cycles. The survey has proved that only few predictions technique has been used still far to in the area of modeling which states that the state-of-the-art is still immature. It has also been found that several open research challenges still need to be addressed in the future which includes the need to focus on the miniaturized generic harvesters. This can later be used in different environments with dynamic energy sources. The major reason for deploying energy harvesting technique is due to the major problem faced by WSN regarding energy. In cases if the energy of a sensor node depletes then it no longer plays its role unless and until a new source of energy is used or some harvesting technique has not been introduced to fulfill the energy gap. Ulukus, Sennur, et al. "Energy harvesting wireless communications: A review of recent advances." IEEE Journal on Selected Areas in Communications 33.3 (2015): 360-381. 4. This article summarizes the application of energy harvesting in a broad area of wireless communication network. This article has covered a variety of topics which includes the information-theoretical and physical layer of performance limit to the scheduling policies and medium access control protocol. This article also discusses about the emerging model of energy transfer and cooperation that occurs with the information transfer of the wireless network. The article has also presented a model of total energy consumption. The threats faced by energy harvesting from physical and practical concerns has made this technique face new challenges. Taking practical conditions mathematical formulas are designed which increases the set of possibilities. The discussion of the energy and information transfer provides exciting possibilities that can be adapted in the future to adapt the network operations with improved performance.
