In the beginning of this article, we survey the security solutions of seven FI architectures, namely XIA, RINA, NENA, SONATE, Mobility-First, NDN, and SONATE, based on literatures, prototypes, and demonstrations. It has been found that none of the architectures can fulfill all of the security goals: confidentiality, authentication, integrity and availability. Further in this article, we focus on eXpressive Internet Architecture (XIA) as it is the most secure and open-source Content-Centric Network (CCN). CCN is claimed by the Future Content Networks (FCN) Group to be the Future Internet. However, XIA does not have any mechanisms to mitigate the replaying attack, thus, this article proposes and implements a solution to mitigate it. Several existing solutions have been analyzed to derive the requirements for the proposed solution. By implementing the proposed protocol, XIA is now able to mitigate all of the reviewed network attacks. The evaluation shows that the proposed solution is more secure and less complex over the existing solutions.

Meanwhile, FSO communication has been regard as an attractive solution to bridging the gap between the wireless communications and optical fiber communications. However, a significant performance degradation in FSO communication system due to the atmospheric turbulence impairs the transmission performance improvement. FSO system employing the spatial diversity technique can be used to mitigate the effect of turbulence and improve the transmission performance. In this paper, a novel analytical approach is presented to evaluate the transmission performance of OFDM-FSO system with diversity reception considering effect of channel correlation.Adetailed mathematical model for OFDM-FSO system over turbulent channel modeled by correlated Log-normal distribution is provided.

It is like opening one’s network doors of say home, companies and organizations to the world where it increases efficiency but at any case should not compromise security by exposing sensitive information, presenting tremendous challenge towards access control and identity management in FI. A well-managed identity management system should provide necessary tools for controlling user access and access to critical information. A fitting example will be the IoT (Internet of Things) where every object will be smart and will take advantage of cloud for storage and processing power. In this paper we provide an introduction to Identity and access management in FI followed by a simplified architecture of the FI and its components. We then proceed by providing a short description about the frequent threats to data stored on cloud along with possible mitigation techniques to the threats.We also provide a comparative study of existing work on access control and propose a method to overcome the limitation of the existing techniques where sensitive organizational information (access policy) is exposed to the cloud. We address this issue in IAMFI by extending the Attribute based encryption Journal of ICT, Vol. 2 1, 1–36. doi: 10.13052/jicts2245-800X.211 c © 2014 River Publishers.

Terminals generally adopt flat rate tariff and the traffic is increasing rapidly. To solve this problem, new technology developments and new spectrum resource allocations and assignments are intensively executed. However in quite near future, traffic will overcome this action.This paper proposes the traffic offloading to microcells and give numerical guideline of offloading ratio that minimize the total radio base station cost under the existing spectrum resource allotment. First, offload guideline is derived based on the Japanese congested area case study in Shibuya ward, and this guideline is translated and generalized to global circumstances. Using the guideline, the required offloading year is calculated for the high population cities or wards in the world. From the results of the analyses, it is shown that the traffic offloading to microcell is necessary in near future. This result is valuable and inevitable to minimize increasing spectrum allotment to the existing mobile service. To monitor the offload ratio, it is better to analyze social bigdata and the carrier’s bigdata. In the final part, example of Draft Question for ITU-R is proposed.","PeriodicalId":394466,"journal":{"name":"J.
