A Versatile Stochastic Dissemination Model

This paper considers a highly general dissemination model that keeps track of the stochastic evolution of the distribution of wealth over a set of agents. There are two types of events: (i) units of wealth externally arrive, and (ii) units of wealth are redistributed among the agents, while throughout Markov modulation is allowed. We derive a system of coupled differential equations describing the joint transient distribution of the agents’ wealth values, which translate into linear differential equations when considering the corresponding means and (co-)variances. While our model uses the (economic) terminology of wealth being distributed over agents, we illustrate through a series of examples that it can be used considerably more broadly. Indeed, it also facilitates the analysis of the spread of opinions over a population (thus generalizing existing opinion dynamics models), and the analysis of the dynamics of a file storage system (thus allowing the assessment of the efficacy of storage policies).

µFuncCache: A User-Side Lightweight Cache System for Public FaaS Platforms

Building cloud-native applications based on public “Function as a Service” (FaaS) platforms has become an attractive way to improve business roll-out speed and elasticity, as well as reduce cloud usage costs. Applications based on FaaS are usually designed with multiple different cloud functions based on their functionality, and there will be call relationships between cloud functions. At the same time, each cloud function may depend on other services provided by cloud providers, such as object storage services, database services, and file storage services. When there is a call relationship between cloud functions, or between cloud functions and other services, a certain delay will occur, and the delay will increase with the length of the call chain, thereby affecting the quality of application services and user experience. Therefore, we introduce μFuncCache, a user-side lightweight caching mechanism to speed up data access for public FaaS services, fully utilizing the container delay destruction mechanism and over-booked memory commonly found in public FaaS platforms, to reduce function call latency without the need to perceive and modify the internal architecture of public clouds. Experiments in different application scenarios have shown that μFuncCache can effectively improve the performance of FaaS applications by consuming only a small amount of additional resources, while achieving a maximum reduction of 97% in latency.

InDaMul: Incentivized Data Mules for Opportunistic Networking Through Smart Contracts and Decentralized Systems

The rise of Internet-of-Things enables the development of smart applications devoted to improving the quality of life in urban and rural areas, thus fostering the creation of smart territories. However, some dislocated areas are underprivileged in providing such services due to the lack, inefficiency, or excessive cost of Internet access. Opportunistic networking techniques might aid in surmounting these problems. In this article, we propose a framework that relies on an untrusted Data Mule to carry data from an offline source to an online destination. In particular, we present a framework that enables the communication between different actors and a reward mechanism using Distributed Ledger Technologies, Smart Contracts, and Decentralized File Storage. The protocol involved in bringing a Client’s message online and getting back a response is thoroughly explained in all its steps and then discussed on the most important trust and security issues. Finally, we evaluate such a protocol and the whole framework through a series of communication latency tests, an analysis of the Smart Contract usage, and simulations in which buses act as Data Mules. Our results suggest the feasibility of our proposal in a smart territory scenario.

Literature Review: Penerapan Teknologi Informasi dalam Meningkatkan Kualitas Pelayanan Publik

The number of complaints submitted by the public about the poor process of public services provided is a problem that must be immediately addressed by the Government. Along with the current advances in information technology, many institutions or agencies have begun to overhaul work systems in order to improve the quality of service to the public. This research aims to identify the application of information technology in improving the quality of public services. This research uses descriptive qualitative methods and the research sources used are secondary data, namely studies of literature, articles, journals, regulations, and sites on the internet related to this research. Validity data in study using triangulation. This study uses the theory of service quality, namely tangibles, reliability, responsiveness, assurance, and empathy. The findings of this study are that the application of information technology in improving the quality of public services has not fully run optimally, this can be seen from the dimensions of physical evidence (tangibles) that have not utilized digitalization in optimizing technology so that it requires space and storage space to store files and documents that are increasingly mounting. reliability in technology-based services, information and communication networks is very dependent on the weather, because if there is heavy rain or thunderstorms, the quality of the network becomes weak and even stops so that the process of administering (managing and processing) data becomes slow and can cause inaccuracies, power responsiveness is still not optimal because the services provided are still slow and require a long time

Thr3ebay: E-commerce Dapp using Blockchain

Abstract: Blockchain has the potential to shake the foundation of e-commerce by enabling exchange relations that are trustless and operate without dedicated intermediaries or even central authorities in the case of permissionless blockchains. Furthermore, the exchange of information and value between companies and consumers might change considerably by enabling unified access to immutable data along the entire supply chain. In this paper, we build a Dapp called Thr3ebay which offers buyers and sellers a secure and transparent platform where transactions are conducted directly between participants, without the need for intermediaries. The platform also provides a userfriendly interface for managing wallets and identities, making it easy for users to buy and sell products on the blockchain. We then examine the potential benefits of building a Web3 e-commerce platform, such as increased security, transparency, and trust, as well as the challenges in terms of scalability, user adoption, and interoperability. Key feature of the Thr3ebay Dapp is its integration with various web3 technologies, including IPFS for decentralized file storage, and the Third-web SDK for user authentication and wallet management. The P2P Decentralized app has also developed a custom front-end for the platform using React, making it easy for users to interact with the marketplace. The purpose of building a Web3 e-commerce app is to create a more secure, transparent, and democratic platform for buying and selling goods and services online, while also providing greater trust and confidence for buyers and sellers

Rewarding Developers by Storing Applications on Non-Fungible Tokens

Non-fungible tokens (NFTs) are individual tokens with valuable information stored inside them over blockchain technology. They can be purchased and sold like other physical and virtual art pieces because their worth is mostly determined by the market and demand. The unique data of NFTs render it simple to verify and authenticate their ownership and transfer of tokens between owners. However, in Pakistan, developers cannot acquire different licences to accomplish their projects not because they cannot afford it, but because they cannot invest in every piece of software to accomplish each new sensitive task. Rather, they can render the product platform independent. Considering this technology, this paper provides IT professionals with a new NFT approach and business policies that solely belong to the information technology domain. In addition, this paper also introduces how NFT tokens can hold software applications. Since we can store files, we can let NFTs also store complete applications to help developers in further utilising virtuality and having the metaverse at their fingertips. Whenever they succeed in a project, they never receive rewards, and their skills only pay the bills. In a nutshell, this paper presents a prototype of NFTs that would be further polished to save and utilise applications in a decentralised manner while rewarding the developers.

Discrete Hyperchaotic S-Box Generation for Selective Video Frames Encryption

Cloud computing has become a significant technology with rapid popularization offering many services with highly effective computation and large-scale storage solutions. As multimedia files are growing explosively, securely storing them for authorized access is a major task. Concentrating on video file storage in a public cloud environment, the security and privacy of those outsourced videos are the major concerns. A selective frame encryption approach is proposed to encrypt the semantic elements of the selected frames of High Efficiency Video Coding (HEVC) compressed videos by storing them in the cloud. The semantic elements of HEVC videos are extracted and encrypted by a modified Advanced Encryption Standard (AES) operation in CFB mode with a Substitution-Box (S-Box). A dynamic, nonlinear 2D discrete hyperchaotic mapping-based S-box generation method is proposed to enhance security by providing good confusion, diffusion, and scrambling. The performance analysis of generated S-box and experimental results show that the proposed selective encryption highly resists attacks and encrypts with reduced time complexity.

SECURE FILE STORAGE ON CLOUD USING HYBRID CRYPTOGRAPHY

Our project aims to provide secure file storage for users on the cloud (specifically on AWS S3) by utilizing a hybrid cryptography approach. This involves encrypting files using both AES and RSA algorithms, with the user receiving the encryption key through email. To further enhance security, the key will be hidden behind an image or within a PDF document using steganography techniques. Additionally, the files stored in the S3 bucket will also be encrypted, but instead of encrypting the contents of the file, we will encrypt the file format itself. The file format can be decrypted using the GHE decryption key and software, which will be made available to end-users. Overall, our project aims to provide a robust and secure solution for cloud-based file storage.

File Encryption and Decryption Software

Since the advent of information technology (the internet) a few decades ago, there have been many changes made to the way information is shared and moved between people, between nations, and throughout the whole world. Information security experts are growing worried about how to solve the issue of information "theft," which has been for a long. Today, it is clear that information security is the solution due to the present spread of several recently developed cryptanalysis techniques. To create a file that can be hashed and firmly decrypted by reliable file storage software, our technique in this work is to use the encryption methods of AES and MD5 after a few steps in the encryption process. The key feature of our programme is the addition of those components throughout the encryption process to create a hashed result that is intertwined and immune to eavesdroppers' nasty techniques. Since any form of a file, including binary, text, and other types, may be effectively encrypted, the encryption results have demonstrated that the programme can provide a broad range of file encryption.

Analysis of Distributed File System Replication Using the NDLC Method with Hyper-V Virtual Simulation Machine

The need to access file sharing easily on an organization's computer network was increased. Users didn't have to worry about the number of file server addresses that can be accessed and are made with only one access address to use file sharing. The availability of data on the network to file storage availability in an organization was also essential. Data would be permanently lost, following a reason including hardware failure, or even accidentally deleted. It was important to ensure that there was a copy of the data. Achieving good data availability requires a system strategy built in the organization's data center. This research used Distributed File System Replication (DFSR) based on active directory domain services with Windows Server. The research method used NDLC (Network Diagram Life Cycle) method. This research was conducted through analysis with the Hyper-V virtual simulation machine. The results of the research with this simulation are that the Distributed File System (DFS) makes it easy for users to access file shares on several file server nodes using only one URL address. DFSR makes it easy for users to clone files automatically on multiple nodes file servers at other locations. DFSR, with its Share and Publish features, provide good data availability. If one of the file server nodes experiences an interruption, the file server nodes at another location would be taken over to provide the data. This system makes it easy for administrators to manage file servers

The Design and Implementation of a Secure File Storage on the Cloud using Hybrid Cryptography

In recent years, cloud computing has become a popular way of storing and sharing data. However, security concerns have been raised about the safety of sensitive information stored on the cloud. Hybrid cryptography, which combines symmetric and asymmetric encryption, has been proposed as a solution to these concerns. This paper proposes a new hybrid cryptography approach for secure file storage on the cloud regardless of the type of deployment model i.e., either public cloud, private cloud, or hybrid cloud. The proposed approach uses a combination of the Advanced Encryption Standard (AES) algorithm, Triple Data Encryption Standard (DES) algorithm, and Rivest cipher 6 (RC6) algorithms are used to provide block-wise security to data. LSB steganography technique is introduced for key information security.

New tool in python for spectroscopic data analysis: Application to variable stars data from the Oukaimden and OHP observatories

Recently we have carried out a campaign of measurements of variable star spectra at the Oukaimeden observatory since 2013. To analyze thousands of spectra, we developed a graphical interface using Python.The spectroscopic study of variable stars is based on the acquisition of data in the observatory, and their storage in Fits files. We treat this data digitally to make them exploitable and graphically representable, for this purpose we use special software or scripts developed by astrophysicists. To facilitate analysis and meet our needs, we developed a graphical interface using Python and used the Tkinter module to represent our spectroscopic data graphically. This interface can plot figures of our spectra in 1D curve, and as a superposition in 1D and 2D. Thus, this interface can determine the necessary parameters in the spectroscopic study of short-period variable stars; such as the pulsation phases, the Blazhko phase, the correction for the heliocentric velocity, etc. Moreover, we can use this interface to convert the pre-treated Fits files into text files as well as to create Excel tables containing the calculated parameters. This interface is easy and fast to use and can provide high-quality figures.By exploiting the potential of this graphical interface, we were able to carry out a study of the influence of the Blazhko effect on the Van Hoof effect which occurs between the metallic lines FeIλ4920.509 Å and FeIIλ4923.921 Å in RR Lyr.

Preserving Integrity of Evidence with Blockchain Technology in Cloud Forensics for Immigration Management

As the popularity of cloud computing increases, safety concerns are growing as well. Cloud forensics (CF) is a smart adaptation of the digital forensics model that is used for fighting the related offenses. This paper proposes a new forensic method relying on a blockchain network. Here, the log files are accumulated and preserved in the blockchain using different peers. In order to protect the system against illegitimate users, an improved blowfish method is applied. In this particular instance, the system is made up of five distinct components: hypervisor (VMM), IPFS file storage, log ledger, node controller, and smart contract. The suggested approach includes six phases: creation of the log file, key setup and exchange, evidence setup and control, integrity assurance, agreement validation and confidential file release, as well as blockchain-based communication. To ensure efficient exchange of data exchange between the cloud provider and the client, the methodology comprises IPFS. The SSA (FOI-SSA) model, integrated with forensic operations, is used to select the keys in the best possible way. Finally, an analysis is conducted to prove the effectiveness of the proposed FOI-SSA technique.
