A Controller-Based Architecture for information Centric Network Construction and Topology management

China Communications 2018年第7期15卷 131-145页

作者： Zeinab Zali Massoud Reza Hashemi Ilaria Cianci Alfredo Grieco Gennaro Boggia Department of Electrical and Computer Engineering Isfahan University of Technology DEI Dep.of Electrical and Information Engineering

information-Centric Networking(ICN) has recently emerged as a result of the increased demand to access contents regardless of their location in the network services. This new approach facilitates content distribution as a service of the network with lower delay and higher security in comparison with the current IP network. Applying ICN in current IP infrastructure leads to major complexities. One approach to deploy ICN with less complexity is to integrate ICN with Software Defined Networking(SDN). The SDN controller manages the content distribution, caching, and routing based on the users' requests. In this paper, we extend these context by addressing the ICN topology management problem over the SDN network to achieve an improved user experience as well as network performance. In particular, a centralized controller is designed to construct and manage the ICN overlay. Experimental results indicate that this adopted topology management strategy achieves high performance, in terms of low failure in interest satisfaction and reduced download time compared to a plain ICN.

Various methods have been suggested for detecting injection vulnerabilities in web-based applications by now. However, some injection vulnerabilities are not only web-based but also occur in stand-alone applications, i. e., SQL injection and OS command injection. Detecting the injection vulnerabilities in these applications is a challenge when their source code is not *** this paper, we present a smart fuzzing method for detecting SQL injection and OS command injection vulnerabilities in the executable codes of stand-alone applications. Our fuzzer employs the concolic（concrete + symbolic） execution method to calculate symbolic path constraints for each executed path in the executable code of the target program. Also, it calculates vulnerability constraints for each executed path to determine what input data makes the intended vulnerabilities active in that path. The calculated constraints are used to generate new test data that traverse as many execution paths as possible and detect the vulnerabilities in each executed path. We have implemented the proposed smart fuzzer as a plug-in for Valgrind *** implemented fuzzer is tested on different groups of test programs. The experiments demonstrate that our fuzzer detects the vulnerabilities in these programs accurately.

This work defines an entropy-based measure aimed to establish the compression limits of wavelet-based image coding. This measure serves to appraise the efficiency of current codecs, determining whether there is margin for their improvement or not. Also, it may help to design new compression schemes that target a particular type of images and/or compression rates, and may assess the decorrelation efficiency of different transform strategies.

Multipurpose watermarking based on blind vector quantization (BVQ)

Journal of information Hiding and Multimedia Signal Processing 2011年第3期2卷 236-246页

Several different digital watermarking methods have been researched and proposed in the last ten years. However, most of the proposed methods focused on a single purpose. Recently, some multipurpose watermarking methods have been proposed, but most of them were focused on combining copyright protection and integrity verifi- cation. In this paper, we propose a multipurpose watermarking method that provides copyright protection, integrity verification, and simultaneous identification of malicious and non-malicious attacks. Additionally, a novel mechanism called blind vector quan- tization (BVQ), which is used to generate authentic information and to verify that the received image is authentic, is also proposed. These capabilities allow improved transmis- sion performance relative to the performance of traditional watermarking methods based on vector quantization. The results obtained in our experiments verified the beneficial effects of the proposed method. © 2011 ISSN 2073-4212.

This paper presents a new method that solves a mixed constraints problem by transforming it into a mixed integer programming problem. The method builds the connection between the feasibility of a mixed constraint problem and the solution to a mixed integer programming problem. The correctness of this method is proven. This method will be beneficial for the further integration of constraint programming and optimization methods.

In the last decade, the request for Internet access in heterogeneous environments keeps on growing, principally in mobile platforms such as buses, airplanes and trains. Consequently, several extensions and schemes have been introduced to achieve seamless handoff of mobile networks from one subnet to another. Even with these enhancements, the problem of maintaining the security concerns and availability has not been resolved yet, especially, the absence of authentication mechanism between network entities in order to avoid vulnerability from attacks. To eliminate the threats on the interface between the mobile access gateway (MAG) and the mobile router (MR) in improving fast PMIPv6-based network mobility (IFP-NEMO) protocol, we propose a lightweight mutual authentication mechanism in improving fast PMIPv6-based network mobility scheme (LMAIFPNEMO). This scheme uses authentication, authorization and accounting (AAA) servers to enhance the security of the protocol IFP-NEMO which allows the integration of improved fast proxy mobile IPv6 (PMIPv6) in network mobility (NEMO). We use only symmetric cryptographic, generated nonces and hash operation primitives to ensure a secure authentication procedure. Then, we analyze the security aspect of the proposed scheme and evaluate it using the automated validation of internet security protocols and applications (AVISPA) software which has proved that authentication goals are achieved.

Personal computers and the Internet are used in different areas and are easier to use. Most data is easy to transmit and duplicate in digital format, and being tampered with and stolen easily leads to issues for content owners and service providers. The Paper describes a secure (tampering-resistant) method for watermarking images for protection and authentication and digital media like audio, video, and multimedia data, and a combination of singular value decomposition (SVD) and Discrete wavelet transform (DWT) for insertion watermark by MATLAB to increase accuracy, simplicity, and flexibility Readability, secure robustness, and imperceptibility the visibility of the image. The proposed algorithm consists of three main steps: Firstly, we decomposed the original image into four sub-bands and the original watermark. Secondly, embed the watermark in the LL sub-band by replacing the singular value for the watermark. Finally, embed a watermark in the other three sub-bands by adding LL values for a watermark in each sub-band in the original image. © 2024 IEEE.
