Smart city is a concept of digitalizing the ecosystem to solve many urban area issues such as crime reduction, transportation, waste management, and governance. However, the security and threat-related issues are still neglected. This paper presents a secure smart city framework using an identity-based signature (IBS) scheme. It is challenging to employ IBS for a smart city (a large network size) due to its key escrow nature. So, we first proposed an identity-based signature scheme that mitigates the trust on a single private key generator (PKG) by employing multiple authorities to preserve the privacy of user’s private key via threshold cryptography. The system also offloads the key protection overhead to the multiple edge gateway, making the system as efficient as the generic IBS. We demonstrate the proposed scheme is secured against the following required attacks: forgeable attack, user slander attacks, and key abusing attacks assuming the computational Diffie-Hellman problem (CDHP) in the random oracle model (ROM). Additionally, the proposed system allows the recipient to verify multiple message-signature pairs at the least cost. The performance analysis determines the optimal signature size and least computational cost compared to related systems making the proposed system suitable for implementing a secure smart city.

Blockchain being a leading technology in the 21st century is revolutionizing each sector of life. Services are being provided and upgraded using its salient features and fruitful characteristics. Businesses are being enhanced by using this technology. Countries are shifting towards digital currencies i.e., an initial application of blockchain application. It omits the need of central authority by its distributed ledger functionality. This distributed ledger is achieved by using a consensus mechanism in blockchain. A consensus algorithm plays a core role in the implementation of blockchain. Any application implementing blockchain uses consensus algorithms to achieve its desired task. In this paper, we focus on provisioning of a comparative analysis of blockchain’s consensus algorithms with respect to the type of application. Furthermore, we discuss the development platforms as well as technologies of blockchain. The aim of the paper is to provide knowledge from basic to extensive from blockchain architecture to consensus methods, from applications to development platform, from challenges and issues to blockchain research gaps in various areas.

Blockchain technology, the fundamental technology of Bitcoin, is featured with high transparency, decentralization, traceability, tamperproof nature, and anonymousness. In this thesis, a case study of the traceability of agricultural products is to explain a traceability solution of agricultural products supply chain based on blockchain and IPFS. The latter one is used to store large quantities of transactions data; and the former one is used for the safety of data storage and circulation. And consumers can know the quality of agricultural products in the shortest time through the evaluation function. As shown in the experiment, the solution is more efficient and secure compared with existing supply chain traceability methods, meeting the traceability requirements of security, transparency, and reliability. Furthermore, the traceability, safety, and performance of the scheme are also analyzed here.
