In this paper, we present a novel lightweight protocol for data integrity in wireless sensor networks. Our protocol is based on leapfrog strategy in which each cluster head verifies if its previous node has preserved the integrity of the packet using the secret key it shares with two hop up tree node. The proposed protocol is simple. The analysis and simulation results show that the protocol ne...

The acquisition of massive remote sensing data makes it possible to deeply fuse and artificial intelligence (AI). mobility cost advantages new platforms in the Internet Things (IoT) make them ideal for continuous deployment rather than traditional airborne platforms. However, devices are vulnerable malicious attacks privacy leaks when sharing due complex architecture heterogeneity IoT lack a un...

Ever since lightweight cryptography emerged as one of the trending topics in symmetric key cryptography, optimizing implementation cost MDS matrices has been center attention. In this direction, various metrics like d-XOR, s-XOR and g-XOR have proposed to mimic hardware cost. Consequently, efforts also made search for optimal dimensions relevant cryptographic applications according these metric...

regarding the increasing demand for lightweight concrete especially lightweight structural concrete, and safety requirements underlined in 2800 iranian standard, research to achieve the optimized results in lightweight concrete production seems inevitable. since, one of the commonly used methods for producing the light eight concrete, utilizes the light weight aggregates with significant role i...

Data protection is an increasingly important issue in today’s communication networks. Traditional solutions for protecting data when transferred over a network are almost exclusively based on cryptography. As a complement, we propose the use of multiple physically separate paths to accomplish data protection. A general concept for providing physical separation of data streams together with a th...

Voluntary peer collaboration is often assumed in media access, route discovery, packet forwarding, and upper-layer protocols designed for wireless ad hoc networks. This assumption has been seriously challenged when peers are autonomous, selfish, ormalicious in large-scale, heterogeneous networks. In this paper, based on the latest advances in identity-based cryptography, we design a lightweight...

In 2013, Rostami et al. proposed a pairing protocol to authenticate device programmers to Implantable Medical Devices (IMDs) based on (lightweight) public-key cryptography and a commitment scheme. Their solution is built upon “touch-to-access”, a novel access-control policy where a device programmer can access an IMD only if it can touch the patient’s skin to measure his heart rate. In this pap...
