A Lightweight Security Protocol for NFC-based Mobile Payments

© 2016 Published by Elsevier B.V. In this work, we describe a security solution that can be used to securely establish mobile payment transactions over the Near-Field Communication (NFC) radio interface. The proposed solution is very lightweight one; it uses symmetric cryptographic primitives on devices having memory and CPU resources limitations. We show that our approach maintains the security of NFC communications and we further demonstrate that our solution is simple, scalable, cost-effective, and incurs minimal computational processing overheads

DocCert: Nostrification, Document Verification and Authenticity Blockchain Solution

Many institutions and organizations require nostrification and verification of qualification as a prerequisite for hiring. The idea is to recognize the authenticity of a copy or digital document issued by an institution in a foreign country and detect forgeries. Certificates, financial records, health records, official papers and others are often required to be attested from multiple entities in distinct locations. However, in this digital era where most applications happen online, and document copies are uploaded, the traditional signature and seal methods are obsolete. In a matter of minutes and with a simple photo editor, a certificate or document copy may be plagiarized or forged. Blockchain technology offers a decentralized approach to record and verify transactions without the need for huge infrastructure investment. In this paper, we propose a blockchain based nostrification system, where awarding institutions generate a digital certificate, store in a public but permissioned blockchain, where students and other stakeholders may verify. We present a thorough discussion and formal evaluation of the proposed system.Comment: The Fifth International Conference on Blockchain Computing and Applications (BCCA 2023), held in Conjunction with Kuwait Fintech and Blockchain Summit 2023, 24,26 Oct 2023, Kuwait City, Kuwai

Privacy-Preserving and Efficient Aggregation for Smart Grid based on Blockchain

In this paper, we address the problem of privacy-preserving of the consumer’s energy measurements in the context of the SG. To this end, we present a blockchain-based approach to preserve the privacy for smart grid users and to detect data forgery, replay attacks, and data injection attacks

Long-term integrity and non-repudiation protocol for multiple entities

© 2017 Smart cities aim at developing new applica-tions and architectures to improve the quality of urban services. However, privacy and security are still two of the technical issues that remain unsolved. The reason is that traditional solutions such as Public Key Infrastructures (PKI) were created to ensure some security services such as non-repudiation and data integrity. PKI enable the use of digital certificates and public key cryptosystems and require the cooperation among multiple entities to verify the certificates validity and to maintain a certificate revocation list. Due to the latest development in quantum computing, PKI-based solutions will not be able to provide continuous data integrity and non-repudiation. In fact, the techniques used by today PKI-based solutions to sign docu-ments are not future-proof. To address these drawbacks, we propose an efficient, lightweight non-repudiation protocol for multiples entities that makes use of Merkle tree and of a Hash function that is future-proof. In contrast to PKI-based solutions, we demonstrate the efficiency of our proposed approach in terms of its low transmission and message overheads, and ability to maintain continuous data integrity and non-repudiation for smart cities’ applications and services

Urban sensing: Towards security efficient sensing network scheme

© 2019 IEEE. The recent advancements in information and communication technologies are tackling problems in cities that do strive for urbanization; from economy and transportation, to sustainable and luxury life style. The concept of smart cities is being widespread and several suggested sensing paradigms are currently adopted. Participatory sensing applications offer plenty advantages over the traditional networking sensors, however; its applicability is highly dependent on the voluntary participation of its owners which can be strictly bounded by security challenges. This paper highlights the security concerns in the context of urban sensing scheme and their direct implications on the embracement of such a paradigm. Moreover, it surveys suggested countermeasures to overcome the possible exposure of user\u27s private information. The research\u27s findings formulate the required knowledge upon which more robust and rigid urban sensing scheme can be visualized
