Abstract Recently, Internet‐of‐Things (IoT) based applications have shifted from centralized infrastructures to decentralized ecosystems, owing user data's security and privacy limitations. The shift has opened new doors for intruders launch distributed attacks in diverse IoT scenarios that jeopardize the application environments. Moreover, as heterogeneous autonomous networks communicate, intensify, which justifies requirement of trust a key policy. blockchain‐based solutions been proposed...
Road accidents and traffic congestion severely impact road safety, resulting in significant loss of life property. Therefore, there is a need for safety management. The wireless networks connected vehicles called Vehicular Adhoc Networks (VANETs) are designed to improve the management on highways with comfort drivers passengers. However, develop an authentication scheme that can protect privacy secure them against attacks such as insider repudiation attacks. In this article, we present...
In wireless sensor networks, secure data aggregation protocols target the two major objectives, namely, security and en route aggregation. Although of reverse multi-cast traffic improves energy efficiency, it becomes a hindrance to end-to-end security. Concealed aim preserve privacy readings while performing However, use inherently malleable homomorphism makes these vulnerable active attackers. this paper, we propose an integrity preserving protocol. We symmetric key-based homomorphic...
Recently, blockchain-based IoT solutions have been proposed that address trust limitation by maintaining data consistency, immutability, and chronology in environments. However, ecosystems are resource-constrained low bandwidth finite computing power of sensor nodes. Thus, the inclusion blockchain requires an effective policy design regarding consensus smart contract environments heterogeneous applications. Recent studies presented as a potential solution IoT, but view to meet end...
In this paper we have proposed digital watermarking scheme for halftone images based on visual cryptography scheme.The does not embed the watermark directly image instead will be divided into parts called as shares.The only protects but also provides an effective copyright protection scheme.At time of embedding verification share is generated and at extraction master using (2, 2) scheme.Verification are used to extract pattern.The experimental results show that robust transparent against...
Due to the renewable and natural energy resources, there exist many opportunities use smart grids meters that enhance efficiency. With increasing supply requirements of energy, grid models have been proposed in literature. One most popular is centralized sharing model. However, model vulnerable reliability issues such as a single point failure. model, maintaining trust becomes challenging issue. In this article, we propose blockchain-based trading solve namely, failure, load balancing, price...
In healthcare systems, users require keys and certificates to communicate share electronic health records (EHRs). The traditional EHR sharing system typically involves a single centralized trusted third-party (STTP) for authentication, auditing, key generation, storing managing patients' EHRs. To securely collect EHRs from multiple hospitals, perform cryptographic operations. operations that are generated by STTP. However, compromised or malicious STTP can disclose the users' information is...
