SSH-DAuth: Secret Sharing based Decentralized OAuth using Decentralized Identifier

Published in , 2023

OAuth2.0 is a Single Sign-On approach that helps to authorize users to log into multiple applications without re-entering the credentials. Here, the OAuth service provider controls the central repository where data is stored, which may lead to third-party fraud and identity theft. To circumvent this problem, we need a distributed framework to authenticate and authorize the user without third-party involvement.

A Novel Approach to Build Privacy and Trust in Vehicle Sales Using DID

Published in , 2023

Decentralized identity solutions, built on the concept of Self-Sovereign Identity (SSI), have gained a competitive edge over existing identity management (IM) systems. This paper discusses the significance of decentralized identifier (DID) and verifiable credential (VC) in a peer-to-peer application for selling and managing pre-owned vehicles. The application uses Ethereum’s ERC-1056 lightweight DID standard.

Evaluation of Wireless Access Point Security and Best Practices for Mitigation

Published in , 2022

The necessity for safeguarding wireless networks has increased due to an increase in the number of associated cyber-attacks on unsecured and weak wireless networks. It is critical for individuals, homeowners, and businesses to protect their wireless networks from external hackers. Wardriving is the act of an attacker foraging for wireless networks while driving a vehicle or while using a laptop or a smartphone. It is an efficient method for gathering information about nearby Wireless Access Points (WAPs), which aids in the analysis of a particular WAPs weakness.

Open-Source Cryptocurrency Forensic Framework

Published in , 2022

In 2008, an unnamed person or group with the pseudonym ‘Satoshi Nakamoto’ introduced Bitcoin through a Whitepaper “A Peer-to-Peer Electronic Cash System”. Since then, both the number of users and the value of Bitcoin have grown. Bitcoin also introduced the concept of Blockchain Technology, which has now broadened to cover industries such as supply chain management, crowdfunding, open governance, education credentialing, health care, digital rights management, and Automotive

Distributed Identity and Verifiable Claims Using Ethereum Standards

Published in , 2022

Identity management is an inevitable part of the proper delivery of schemes and services to individuals by the government and private organizations. Identity management encompasses the creation and maintenance of identity. It ensures that the right entity gains access to the right resources at the right time for verification. It also involves providing high security, privacy, productivity, and enhanced user experience.

Blockchain Framework for Social Media DRM Based on Secret Sharing

Published in , 2020

Huge adoption of the Internet into our daily lives generates at least few MBs of data. Social media in modern age enabled every single user with a smartphone and Internet to be a marketer, journalist, publisher and content creator. Ensuring protection and copyright of social media data like images, videos and audios are extremely demanding. Copyright infringement happens easily, and protecting the content for its originality and authenticity should be simplified.

Blockchain for the Internet of Vehicles

Published in , 2019

Recent advancements in the Internet of Things and mobile internet helped the development of traditional Vehicular Adhoc-NETwork (VANET) based systems into the Internet of Vehicles (IoV). Vehicles in IoV make decisions based on the information from other vehicles and roadside infrastructure. This information helps them make critical decisions and alert the user about unpredictable situations. Security and privacy concerns in vehicles are increasing, hence it is important to address these issues, thus preventing malicious nodes transmitting falsified information or tampering critical communication data.

Blockchain based Waste Management

Published in , 2019

The environment is the most sought-after topic for discussion in global forums because of the alarming threat it faces. Waste Management is one of the major challenges after global warming that affects the environment and harmony of nature. Government and non-governmental organisations are working towards solutions for better waste management. Though in present-day technology is part of waste management, it is not an integral part of waste management in many countries. Current technology only helps in reducing manual intervention by automating waste collection and transportation. It also helps in the disposal of non-useful waste and recycles/reuse useful waste by converting them into raw materials. People are the major part of the waste management cycle, so without their involvement, it is extremely difficult to make any technology-based system successful. People’s involvement in waste management would increase if they are incentivized for proper segregation of wastes, reusing, recycling, disposal and even for spreading awareness. The supportive technology should automatically monitor waste management cycle, record important actions and react accordingly.
