Abstract

A smart device uses information technology to integrate and manage physical, social, and business infrastructures data in order to provide better services to its dwellers while ensuring efficient and optimal utilization of available resources. With the proliferation of technologies such as Internet of Things (IoT), cloud computing, and interconnected networks, for securing smart devices, they can deliver a lot of innovative solutions. Despite a number of potential benefits, digital disruption poses many challenges related to information security and privacy. Here, this project proposes a security framework that integrates the blockchain technology with smart devices to provide security to smart devices.

Introduction

I. INTRODUCTION

The project aims to prevent security hacks on smart devices by using blockchain technology. The blockchain ensures that only registered or access-granted users' data is securely stored, and the data cannot be tampered with, such as adding new fingerprints or modifying it. Smart contracts are written and deployed into the blockchain, which act as the rules or functionality of the devices, and once deployed, they cannot be modified. Blockchain has several properties that make it difficult to modify data, and data can only be modified by "Data Miners" who solve a resource-consuming cryptographic puzzle called Proof of Work (POW). However, this may not be a 100% correct solution as blockchain is a relatively recent technology, and it can only be implemented through cryptocurrency. This means that users must have cryptocurrency to access the device, which may not be feasible for all users. Nevertheless, the project is attempting to implement another way of providing a solution using blockchain technology. In summary, the proposed security framework integrates blockchain technology with smart devices to ensure that only authorized users can access and modify the data. The use of blockchain ensures that the data is secure and tamper-proof, and smart contracts ensure that the device functions according to the rules set forth in the blockchain. While there may be limitations to implementing blockchain technology due to its recent development and reliance on cryptocurrency, this project demonstrates the potential for using blockchain technology to secure smart devices.

II. LITERATURE SURVEY

1. Sunny King: In a blockchain, not everyone can modify the data as specific nodes called miners are responsible for mining blocks. To mine a block, miners solve complex cryptographic puzzles with rewards for solving them. To maintain the security property of Nakamoto's Bitcoin, a prime chain is linked to the block hash. The prime chain acts as an adjustable-difficulty proof-of-work in a Bitcoin-like cryptocurrency. The solving of the puzzle requires finding a 64-digit hexadecimal number, which makes it very difficult to guess. This time-consuming process results in more time required for modifying IoT data, providing improved security compared to Nakamoto's original Proof of Work technique.
2. Ali Dorri, Salil S. Kanhere, Raja Jurdak: Integrating Blockchain into IoT poses significant challenges, including resource-intensive proof-of-work computations, slow transaction confirmation times, and limited scalability due to network-wide broadcasting. To address these challenges, the Diffie-Hellman algorithm can be employed. Devices can establish secure communication by generating shared keys based on a generalized side. While this approach offers consistent performance overhead, its scalability is dependent on the number of clusters involved. Although there are no major constraints, it may still fall short of meeting the desired processing speed for transactions.
3. Andrey Bogdanov, Miroslav Kneževi?, Gregor Leander, Deniz Toz, Kerem Var?c?, Ingrid Verbauwhede: In this approach, secure communication is achieved by using a shared key for all transactions. Lightweight hashing algorithms are utilized to detect any modifications in transaction content during transmission. All transactions involving the smart home are stored in a local private blockchain. When attempting to guess a number, the emphasis is on utilizing the region and computational power efficiently. The hash function employed adheres to the standard security requirements, providing a 2n/2 collision resistance and preimage resistance. Even a minor change in the data will result in a completely different and unpredictable hash value, making it difficult to compute the hashed number quickly. While this lightweight technique may not possess the same strength as well-known alternatives like SHA hashing, it is implemented to ensure uniqueness and provide an additional layer of security.

III. PROPOSED SYSTEM

The proposed system aims at addressing the high cost of transaction fees associated with hosting smart devices on a blockchain by leveraging the Inter-Planetary File System (IPFS) as a distributed file system. IPFS offers a cost-effective solution by decentralizing data storage and sharing. This approach not only reduces expenses but also enhances security by fragmenting data into multiple blocks, making it challenging for unauthorized individuals to manipulate or access the information. Additionally, IPFS employs content-addressing to ensure data immutability, assigning a unique identifier to each file within a global namespace. This system, combined with the utilization of SHA-256 cryptographic hashing, guarantees the confidentiality and integrity of the stored data. By incorporating IPFS into IoT data storage, we can achieve an efficient and secure solution that surpasses traditional blockchain-based methods.

Here are some advantages of the proposed system:

1. Immutability: Once data is added to the blockchain. It cannot be changed or deleted without the consensus of the network. This ensures that data is tamper-proof and provides high trust.
2. Increased Efficiency: Blockchain eliminates the need for intermediaries, which can help reduce transaction cost and processing times. Additionally, smart contracts can automate many processes, further increasing efficiency.
3. Decentralization: Blockchain technology enables a decentralized network, which means that no single entity controls the system. This provides increased security and resilience, as well as more democratic decision-making.
4. Content Addressing: Establish Each file in IPFS is given a unique content-addressed hash that allows the system to easily locate and retrieve the file from any node on the network.
5. Distributed File System: IPFS creates a global, decentralized file system by connecting all computing devices to a peer-to-peer network.

IV. METHODOLOGY
