Abstract — In Cloud Computing environment, when clients or providers want to authenticate themselves to the cloud, they face some problems like the security level of their credential information to be stolen or by illegal using of their decrypted messages by attackers during the communication process. The service providers and clients delegate a third party to monitor and enforce the datacenter in the infrastructure level of cloud. However, the third party might not be a trusted enough for one of them or for both, so they need to manage their data by themselves. In this paper, I will go over one technique for each issue to solve the privacy problem. Web Service Security model for encrypted and decrypted messages, and Private Virtual Infrastructure model for monitoring the data over cloud.

Keywords — Cloud Computing, Cloud Security, Locator Bot, Virtual Private Infrastructure, Web Service Security.

Abstract — The enhancing cumbersome intricacy of wireless communications technologies and inclusion in a wide range of miscellaneous applications mean the related spectrum management issues are being more complex. Pursuant to this spectrum complexity relates equally to private and public sector use of the spectrum. Changes from an industrial to an informational based society and the associated demand for enhanced communications services push the need for seamless access further. It is likely that removing unnecessary regulatory distinctions between government and non-government spectrum will become increasingly important to maximize the overall benefit derived from use of the spectrum. Many applications of practical interest stem from the capability to monitor and store packet-level traces in a WiFi, WiMAX, 3G and 4G networks. In this approach, yields strong practical benefits, given the costs and complication of accessing network equipments, especially in the Radio Access Network as well as pondering of security. The author of this paper discusses the opportunities to exploit in and addresses challenges faced by the key players in South Asian region and seeks the spectrum commons approach in South Asian countries and concludes that, even in the face of enormous challenges, the potential benefits and opportunities are noteworthy adequate to necessitate grim thoughtfulness by telecommunications policy–makers in their function as spectrum managers.

Abstract — The brisk and mammoth yield of wireless mobile community, coupled with their demands for high speed, wideband, multimedia services, stands in clear contrast to the limited radio spectrum allocated in international agreements. Advanced mobile services combine the innovation potential of reckoning, data communications, and the wireless industry. So, Current Radio Spectrum Management (CRSM) [1] remains as a key challenge to the efficient engineering of mobile wireless networks. Different types of innovation scenarios can be distinguished, depending on the constellation of sunk cost and the cost of coordination between suppliers along the value chain. No single spectrum management framework supports all equally well, although spectrum use markets seem to be most broadly compatible. A mixed approach is possibly superior to any given individual class of spectrum management. Broadening the literature on spectrum policy, the author of this Paper focuses on implications and issues of Current Radio Spectrum Management regimes for rolling out in mobile services in Bangladesh with the current status of Radio Spectrum Management (RSM) polices and outline the key issues in RSM for next generation mobile wireless networks although the development of 3G in many countries new directions are being researched.

Abstract — Digital images are widely used media over the Internet for different purpose. Therefore, security becomes important in the transmission. This paper presents spatial domain multilevel image encryption algorithm based on Arnold cat's map. The algorithm divides the image into different size overlapping blocks along the levels of encryption. The block at level 1 begins at the center of the image and this block is iteratively enlarged in the next levels. In each level of the proposed algorithm, Arnold cat's map is implemented in each level on the block's pixels. Also, zigzag scan is applied on the whole image to further reducing the correlation between adjacent pixels. In order to achieve the diffusion, the pixel values are xored with different xor values begin at a value, which is generated randomly, beside control parameters and iteration number of Arnold cat's map, by using mid-product algorithm with the secret key as an initial seed. The results of experiments indicated that the proposed algorithm is highly decorrelated the adjacent pixels and it resists the statistical attacks. The values of ciphered image entropy are close to the ideal value. Furthermore, the proposed algorithm is very sensitive to key. It was concluded that the use of zigzag scan beside Arnold cat's map in spatial domain was very efficient to hide the statistical characteristics of the image.

Keywords - Image encryption; Arnold cat's map; Zigzag scan; mid-product.

Abstract — In the past few decades wireless networks have become increasingly popular, due to the wide availability and rapid introduction of wireless transceivers into a variety of computing devices such as PDAs, laptop and desktop computers. Global Positioning System (GPS) is used to determine position and speed of objects by using the satellite technology. Furthermore, Radio Frequency is another technology which is used to determine the objects' locations. In this paper we have presented an overview for using the previous technologies to track a stolen vehicle by using a system that is resulted from mixing all of those technologies in addition to proposed an enhancement idea that could help the resulted system to determine the cars' thieves by sending their photos to the security agency base to be recognized.
