A Simple Fast And Memory Efficient Algorithm For Secure Wireless Sensor Networks Essay

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

There are many aspects to security and applications, from secure commerce and payment to private communications and protecting passwords. Cryptography, is the practice and study in securing communication between parties in the presence of potential adversaries (Yousuf, N.D.). This report focuses on modern methods of cryptography its operation, strengths and weaknesses, its application techniques in computing and some other aspects where cryptography deemed essential as discussed in this report.

Wi-Fi can be found anywhere in this day in age, you can walk into almost any establishment and you’ll be sure to find their Wi-Fi, accessible from anywhere within their spaces. Each data packet being transmitted through the air, whether containing private, sensitive or insensitive information, is available for an attacker to capture. To fight against this, there have been some standards that have come out through the years to guard and protect data, such as WPA. All standards have been created to replace the preceding one due to vulnerabilities found in the engineering of them. Still to this day, not every standard is fully secure, attackers still find

Protecting information and critical infrastructure in a cohesive way that quantifies policies and procedures is imperative for implementing a proactive privacy risk management plan. In doing so, you gain the necessary framework and principals to share essential operational data for use in cybersecurity while focusing on policy cohesiveness between intra government agencies, the private sector, and securing critical infrastructures. (Claffy & Kenneally, 2010).

Sending data over a network without third party intervention, and sniffing attacks, is somewhat impossible nowadays with attackers lurking over the networks sniffing the data causing privacy problems especially when the data is being transferred over a decentralized military network which is highly confidential. The idea of this project is to provide a secure means for transmission of data between different DTNs without allowing attackers to sniff data in the network by providing encrypted transmission channel and further securing it with key attributes. This is the initial idea of the proposed project and will update it further.

This topic deals more about the methods and technologies in tandem for en-hancing overall security of any embedded device . At places one can notice that the topics discussed earlier could have criss-crossed here, but here the same discussion is more looked from the prism of overall security rather than arbitrarily which was the case earlier.

I have read the Guide to Avoiding Plagiarism published by the student affairs office. I understand what is expected of me with respect to properly citing sources, and how to avoid representing the work of others as my own. The material in this paper was written by me, except for such material that is quoted or indented and properly cited to indicate the sources of the material. I understand that using the words of others, and simply tagging the sentence, paragraph, or section with a tag to the copied source does not constitute proper citation and that if such materiel is used verbatim or paraphrased it must be specifically conveyed (such as through the use of quotation marks or indentation) together with the citation. I further understand that overuse of properly cited quotations to avoid conveying the information in my own words, while it will not subject me to disciplinary action, does convey to the instructor that I do not understand the material enough to explain it in my own words, and will likely result in a lesser grade on the paper.

The large and growing number of internet and wireless communication users has led to an increasing demand of security measures and devices for protecting the user data transmitted over the unsecured network so that unauthorized persons cannot access it. The increasing need for Secured data communication has led to development of several cryptography algorithms [31]. Cryptography uses the encryption algorithm and a key to send confidential data through an insecure channel[26] There are mainly two types of encryption algorithms, private key (also called symmetric key) and public key. Private key algorithms involve only one key, both for encryption and decryption whereas, public key algorithms involve two keys, one for encryption and other for decryption [29]. The public key algorithm is complex and has very high computation time. Private key algorithm is simple and therefore, it is more suitable for faster implementation [30].

Since, Elliptic Curve Cryptography (ECC) introduced independently in 1985, by Neal Koblitz and Victor S. Miller. ECC Algorithms widely start uses in 2004 to 2005. ECC has become another way to provide security as Public Key Cryptosystem and it has been introduced in many popular standards such as E.g. RSA, ECDH. ECC provide top level of security with a shorter key size. This Research Paper presents all type of Popular Attacks on Elliptic Curve Cryptosystems.

Wireless Sensor Networks (WSNs) present universally and growing rapidly due to its unique features, such as their less weight, cheap, and wireless nature. However, due to its highly constrained computational and energy resources this network is exposed to numerous attacks that affect its security. So, it is important to address these security issues from the beginning of the system design. but, due to inherent resource and computing constraints, security in sensor networks poses diverse challenges than traditional network security so, designing security protocols for all layers in this kind of a network becomes an compelling need. In this paper, we studied several existing WSN security protocols and data link layer security algorithms, which ensures a safe communication link between neighboring nodes by supervising the medium access and handling the errors. The purpose of this paper is Not Only Studying and explaining the strength and limitations of the existing energy efficient security protocols of the data link layer but also and determine the crucial security requirements which should be taken into consideration for design of future of data link security protocols.

Now-a-days, communication had become a major role within the people. Communication is done by a medium with sender and receiver. In internet the way of communication takes place by medium of wired and wireless. There is a rapid growth in both wired and wireless infrastructures. It makes use of the customers for the internet connection in many possible ways .In most of the places wireless internet has been used. Most of the wireless spontaneous network is not secure because it is not a planned network and network boundaries are defined poor, due to the lack of centralized server in the network. Usually wireless networks perform both communication and measurement in a given network.

Abstract— Crucial methods are employed to deploy the majority networks to acquire the data. Modern improvements stores, transfer data at higher rate. Traditional methods which provide security to the information. Using single encryption algorithms are more prone to issues and these are implemented without knowing its shortcomings. This proposed algorithms provides new step to avoid shortcomings. We resemble some famous algorithms as follows. Firstly, we create a new algorithms, In order to provide security issue and time constraint of operation. Secondly, We combine AES using multiplexing of keys, Improvement of DES key size and blowfish algorithm, then we encrypt data using the proposed algorithm. This can enhance the security and complicates the Encryption. In this paper we provide both the encryption and decryption that supports in real time application and algorithm has a practical value.5

Backward secrecy: a joining sensor ought not have the capacity to peruse any already transmitted message. The various threats and attacks in WSN can be classified into [4] following three categories as shown in figure-5.

Designing a foolproof security for ad hoc network is a challenging task due to its unique characteristics such as, lack of central authority, frequent topology changes, rapid node mobility, shared radio channel and limited availability of resources

The domain naming server is a very important component which virtually plays a key role in every internet transaction. DNS plays role of a distributed database that helps in convenient storing and retrieving of data records. DNS now works well and it is also sometimes mentioned that any new changes added to the present DNS may contribute to interruption to its functionality and can also contribute towards additional complexity which is undesirable current networks and future networks rely essentially on DNS and it is important that DNS should be much secured. The DNS can be easy attacked and such attack can cause dire consequences so it specifies the importance to use the secured version of DNS to avoid such consequences. To employ such a version involves more cost. Domain Names are converted into the corresponding IP address by using the Domain Naming Server. There are threats to DNS system like packet interception, query predication and cache poisoning. Data integrity and Data origin authentication are the two essential security requirements to have a secure DNS. We present a survey paper in which we observe the possible attacks on DNS and found that Public key cryptography (PK-DNSSEC) and Symmetric key cryptography (SK-DNSSEC) are the two approaches for secured DNS. SK-DNSSEC cryptography is good for recursive name servers and PK-DNSSEC cryptography is better for referral and authoritative name servers. PK-DNSSEC is suitable for static data and when data is
