“…Denial of service (DoS) attack is a method used to disrupt legitimate users' access to the target network or website resources [33][34][35]. Usually this is achieved by overloading a target with a large amount of traffic (usually a web server), or by sending malicious requests that cause the target resource to malfunction or completely collapse [36][37][38][39][40][41].…”

Distributed storage can store data in multiple devices or servers to improve data security. However, in today's explosive growth of network data, traditional distributed storage scheme is faced with some severe challenges such as insufficient performance, data tampering, and data lose. A distributed storage scheme based on blockchain has been proposed to improve security and efficiency of traditional distributed storage. Under this scheme, the following improvements have been made in this paper. This paper first analyzes the problems faced by distributed storage. Then proposed to build a new distributed storage blockchain scheme with sharding blockchain. The proposed scheme realizes the partitioning of the network and nodes by means of blockchain sharding technology, which can improve the efficiency of data verification between nodes. In addition, this paper uses polynomial commitment to construct a new verifiable secret share scheme called PolyVSS. This new scheme is one of the foundations for building our improved distributed storage blockchain scheme. Compared with the previous scheme, our new scheme does not require a trusted third party and has some new features such as homomorphic and batch opening. The security of VSS can be further improved. Experimental comparisons show that the proposed scheme significantly reduces storage and communication costs.

“…Figure 8 shows the secure connectivity versus the key pool size P in the AP. ere are four solid curves in Figure 8, from bottom to top, corresponding parameters [l, M] of [5,125], [10,250], [15,375], and [20,500], respectively. It is observed that the probability of sharing key increases when the number of preloaded keys increases.…”

“…(27) [4,5,7], in this scheme, the sensor node does not prestore any keys or other key materials, which not only reduces the storage cost of the sensor but also improves the resilience against the sensor capture because the attacker cannot obtain any key that belong to a safe node despite capturing a sensor physically. erefore, our proposal has perfect resilience against the sensor capture; that is,…”

Because of the movements of sensor nodes and unknown mobility pattern, how to ensure two communicating (static or mobile) nodes authenticate and share a pairwise key is important. In this paper, we propose a mutual-authenticated key distribution scheme based on physical unclonable functions (PUFs) for dynamic sensor networks. Compared with traditional key predistribution schemes, the proposal reduces the storage overhead and the key exposure risks and thereby improves the resilience against node capture attacks. Mutual authentication is provided by the PUF challenge-response mechanism. However, the PUF response is not transmitted in plain forms so as to resist the modelling attacks, which is vulnerable in some existing PUF-based schemes. We demonstrate the proposed scheme to improve the secure connectivity and other performances by analysis and experiments.

“…to the Internet. As a result, many applications based on IoT like smart home, smart city, body networks and so on become popular and available which prompt the progress of the human society [2][3][4]. With the fast development of IoT technique [5][6][7], the data generated by IoT systems increases significantly so that traditional methods of data storage cannot match the requirements of data management for IoT systems.…”
