Blockchain for IoT Security and Privacy: The Case Study of a Smart HomeKishor Datta Gupta
Internet of Things (IoT) security and privacy remain
a major challenge, mainly due to the massive scale and
distributed nature of IoT networks. Blockchain-based approaches
provide decentralized security and privacy, yet they involve
significant energy, delay, and computational overhead that is
not suitable for most resource-constrained IoT devices. In our
previous work, we presented a lightweight instantiation of a
BC particularly geared for use in IoT by eliminating the Proof
of Work (POW) and the concept of coins. Our approach was
exemplified in a smart home setting and consists of three main
tiers namely: cloud storage, overlay, and smart home. In this
paper we delve deeper and outline the various core components
and functions of the smart home tier. Each smart home is
equipped with an always online, high resource device, known
as ”miner” that is responsible for handling all communication
within and external to the home. The miner also preserves
a private and secure BC, used for controlling and auditing
communications. We show that our proposed BC-based smart
home framework is secure by thoroughly analysing its security
with respect to the fundamental security goals of confidentiality,
integrity, and availability. Finally, we present simulation results
to highlight that the overheads (in terms of traffic, processing
time and energy consumption) introduced by our approach are
insignificant relative to its security and privacy gains.

IoT and Blockchain are two evolving technologies which are gradually realizing immense potential to be a decisive part of future of mankind ecosystem. Blockchain and IoT, both are envisaged to bring in a plethora of advantages including better control, communication, transparency and more significantly realizing digital trust without any third party intervention. Both of these technologieshave immense potential for exploitation in a smart nation concept. The advantages being realized are potent enough for definite implementation ahead but they come with an austere package of security concerns which if not taken care at the design stage can lead to pandemonium beyond control because of the billion plus connected things. Even atdesign stage, one can appreciate that it will be envisaging beyond control to close all security vulnerabilities and zero day’s exploits of future. But then Blockchain is an inexpugnable solution to shut all these securities imperils. This paper builds upon the advantages of the union of these two evolving technology behemoths, their union and solutions vide Blockchain to the challenges in the way ahead

IoT and Blockchain Challenges and RisksAhmed Banafa
The biggest challenge facing IoT security is coming from the very architecture of the current IoT ecosystem; it’s all based on a centralized model known as the server/client model. All devices are identified, authenticated and connected through cloud servers that support huge processing and storage capacities. The connection between devices will have to go through the cloud, even if they happen to be a few feet apart. While this model has connected computing devices for decades and will continue to support today IoT networks, it will not be able to respond to the growing needs of the huge IoT ecosystems of tomorrow.
Understanding the different building blocks of IoT, identifying the areas of vulnerability in each block and exploring technologies needed to counter each of the weaknesses are essential in dealing with the security issue of IoT.

IBchain: Internet of Things and Blockchain Integration Approach for Secure Co...AlAtfat
Introducing IBchain, a new blockchain architecture with the Internet of Things (IoT), could be an
attractive framework regarding improvements in connectivity implementation through the smart cities.
Instead of meriting innovation and security, the IoT links people, sites, and products and provides
opportunities. Everything that transfers information to the IoT system is integrated by advanced
microchips, sensors, and actuators in actual things. The analytical ability of the IoT converts observations
into actions, impacting business advancements and significant ways of activity. IoT enables connected
objects to transmit information to personal blockchain systems to create tamper-resistant transaction
records. The information from sensors and microchips is progressing rapidly with blockchain ledgers,
making them more portable and relevant for immediate conversations. In IBchain methodology, the smart
objects are permissible to connect securely with other smart objects in diverse situations. IBchain creates
an innovative blockchain-based processing configuration through the IoT. The IBchain could analyze
blockchain to the main expertise or supports the IoT validation and trustworthiness. It reinforces
blockchain and cloud to build an empowering IoT ubiquitous situation for secure communication among
the smart devices.
Blockchain can be used across the whole manufacturing industry to address all different types of projects and stakeholders. Its value to the manufacturing vertical is promising as Industry 4.0 continues to grow.
Blockchain-based Security Mechanisms for Internet of Medical Things (IOMT)IJCNCJournal
Traditional standards and security protocols are recognized as unable to solve the security, privacy, and availability of services of the Internet of Medical Things (IoMT) ecosystem, especially during the Coronavirus (COVID-19) pandemic. Blockchain technology has then emerged as a distributed ledger technology that can manage many intelligent transactions and ensure greater security in data management. The Blockchain-based security mechanisms with specific adaptation and additional layers of authentication and verification can offer a complete resources' management system. It has demonstrated it’s superlatively as the core component of the Bitcoin cryptocurrency. In this paper, we propose a ThreeTier Blockchain Architecture in a hierarchical clustering network, with a lightweight authentication system-based API Gateway model that provides network and communication security. Reasonable implementation is proposed and the obtained results demonstrate that our approach shows satisfactory performances in terms of transfer time, energy consumption, and CPU impacts. The traffic analysis also shows that the proposed model can meet the requested security, integrity, and confidentiality of user data.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

applications
Higher cost due to maintain centralized data centers and
cloud services
Due to network traffic lags and system down times could
occur.
5. Decentralizing Methods
1. Architectural decentralization: What is the number of the physical computers
present in the network? How many of them can breakdown at the same time without
jeopardizing the entire system?
2. Political decentralization: How many parties control the computers that are part of
the system?
3. Logical decentralization: Can the data structure and interface, function the same
way independently, if the system is split into two parts
6. Advantages and Disadvantages in
