Traumatic and Psychological Implications of Armed Herdsmen Invasion of Southern Kaduna, Nigeria

The research is on traumatic and psychological implications of armed herdsmen invasion of southern Kaduna, Nigeria: A sample of 90 respondents drawn from the five local government areas affected by the activities of armed herdsmen was used for the study. The questionnaire was used as a major instrument for the collection of primary data from respondents; in-depth interviews were conducted to stimulate further information from respondents. Secondary data was sourced from books, journals, newspapers, and online peer-reviewed documents. The routine activity theory was adopted to explain armed herdsmen activities in the Southern Kaduna region of Kaduna State. Findings suggested that armed herdsmen activities have created traumatic and psychological implications on the people of Southern Kaduna who have now been found to live in perpetual fear. The study recommends that government be proactive in curbing the menace of armed herdsmen brigandage in Southern Kaduna and provide a more robust security network through the establishment of more military bases along the borders of the three local governments faced with the challenge of armed herdsmen invasion.

Modeling and Verification of IEEE 802.11i Security Protocol in UPPAAL for Internet of Things

IEEE 802.11i is the IEEE standard that provides enhanced MAC security and has been widely used in wireless networks and Internet of Things. It improves IEEE 802.11 (1999) by providing a Robust Security Network (RSN) with two new protocols: the Four-Way Handshake and the Group Key Handshake. These protocols utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys. In this paper, we carry out a formal modeling and verification approach based on timed automata for IEEE 802.11i protocol, using the UPPAAL model checker, to check correctness of the changes in IEEE 802.11i protocol and provide better security.

A Comparitive Analysis of Wireless Security Protocols (WEP And WPA2)

Wireless local area networks (WLANs) are become popular as they are fast, cost effective, flexible and easy to use. There are some challenges of security and for IT administrators the choice of security protocol is a critical issue. The main motive of this paper is to make the non-specialist reader knowledgeable about threats in the wireless security and make them aware about the disadvantages of wireless security protocols. WEP (Wired Equivalent privacy), WPA (Wi-Fi Protected Access) and RSN (Robust Security Network) security protocols are defined and examined here. This security protocols are compared with the common. This paper is a comparative analysis of WEP, WPA and WPA2. We have tried to perform and check authentication of all 3 protocols by implying the legendary attack vector scripts i.e. Air crack set of tools. The test was conducted on Back Track operating system which is considered as dedicated pentesting operating system. In the test result, we found out that WEP is the weakest, to which WPA was a temporary solution and WPA2 is a very solid and long term solution. This paper is a mixture of wireless security weaknesses and counter measures to the problems faced until recently. After reading this paper the non specialist reader will have complete review and awareness about the wireless security and vulnerabilities involved with it.

High Throughput– Resource Saving Hardware Implementation of AES-CCM for Robust Security Network

This paper presentsa new architecture andASICimplementation of high throughput of Counter with Cipher Block Chaining - Message Authentication Code(CCM) for robust security network such as gigabit wireless IEEE 802.11ac in case considering trade-off between throughput and resource saving. We propose a new architecture of AES-CCM core adopted in parallel which utilizes two separated AES forward cipher cores for MIC calculation in Counter (CTR) Mode and encryption or decryption data in Cipher Block Chaining (CBC) Mode. The implementation of AES-CCM core in Synopsys CMOS SAED90nm process achieves2.69Gbps of throughput at 264MHz clock frequency.The proposed architecture of AES-CCM corereduces latencyby one AES cycle in comparison with conventional architectures. In addition,the AES-CCM core supports bothgeneration-encapsulation and decryption-verifica-tionprocess with symmetrical data processing routine. We also introduce an implementation of reordering AES transformation method comes along with composite Sbox in order to gain maximal period of the composition and saving resources compared to original AES algorithm implementation.  .

Enhancement of Passive MAC Spoofing Detection Techniques

Failure of addressing all IEEE 802.11i Robust Security Networks (RSNs) vulnerabilities enforces many researchers to revise robust and reliable Wireless Intrusion Detection Techniques (WIDTs). In this paper we propose an algorithm to enhance the performance of the correlation of two WIDTs in detecting MAC spoofing Denial of Service (DoS) attacks. The two techniques are the Received Signal Strength Detection Technique (RSSDT) and Round Trip Time Detection Technique (RTTDT). Two sets of experiments were done to evaluate the proposed algorithm. Absence of any false negatives and low number of false positives in all experiments demonstrated the effectiveness of these techniques.

Holistic approach to Wep protocol in securing wireless network infrastructure

Constant increase in use of wireless infrastructure networks for business purposes created a need for strong safety mechanisms. This paper describes WEP (Wired Equivalent Privacy) protocol for the protection of wireless networks, its security deficiencies, as well as the various kinds of attacks that can jeopardize security goals of WEP protocol: authentication confidentiality and integrity. The paper, also, gives a summary of security improvements of WEP protocol that can lead to the higher level of wireless network infrastructure protection. Comparative analysis shows the advantages of the new 802.11i standard in comparison to the previous security solutions. A proposal of possible security improvements of RSNA (Robust Security Network Association) is presented.
