Nowadays, cloud-based storage systems play a vital role in IoT data storage, processing, and sharing. Despite its contribution, the current cloud-based architecture may cause severe data leakage or jeopardize user privacy. Meanwhile, the cloud-based architecture heavily relies on a trusted thirdparty auditor (TPA). Moreover, the TPA runs in a centralized control manner. However, the TPA may not be an entirely trustworthy entity, and a single point of failure might cause the centralized system to collapse. Fortunately, with the advent of blockchain technology, the decentralized storage model has gained popularity. A decentralized storage system successfully eradicates the rule of TPA, solves the problem of a single point of failure, and has many advantages over a centralized control architecture, such as low storage prices and high throughput. This study offers a blockchain-based decentralized distributed storage and sharing scheme that provides end-to-end encryption and fine-grained access control. In our proposed IoTChain model, fine-grained permission is based on attribute-based access control (A-BAC) policy by employing the Ethereum blockchain as an auditable access control layer. Smart contracts are tailored for the IoTChain model, which combines the Ethereum blockchain and the interplanetary file system (IPFS). We used an advanced encryption standard (AES) for encryption and the Elliptic Curve Diffie-Hellman Key Exchange Protocol for secret key sharing between data owners and users. Also, the proof-of-work (PoW) consensus mechanism is replaced with a proof-of-authority (PoA) to minimize system transaction fees and boost system throughput. Additionally, our proposed solution has been tested on Ethereum's official test network, Rinkeby, and the results demonstrate that our approach is realistic and economical on the IoT data.

In satellite communication systems, satellite power and processing capacities are limited, which means that storage and security are also constrained. Satellite communication channels are extremely vulnerable to hackers and external interference signals. Protecting satellite networks from illegal information access and use can be extremely challenging. In this paper, an architecture composed of satellite and ground equipment is developed that integrates communication network authentication and privacy protection structures. In the proposed scheme, the communication, registration, authentication, and revocation of information are achieved through stages to improve communication security. The satellite forwards the collected information to a ground base station, which has a strong data processing capacity. The ground base station records all the key parameters in the distributed blockchain, and all malicious node certificates are removed from the system. To further enhance data transmission security, the key is transferred using an asymmetric encryption algorithm. To measure the robustness of using the proposed network architecture, under the same attack condition, an invulnerability analysis is performed. After conducting simulation experiments, the results show that the proposed scheme greatly improves communication security and protection.INDEX TERMS satellite communication system; communication network authentication; privacy protection scheme; ground base station I. INTRODUCTIONWith the rapid development of computer networks and communication technology, satellite communication has become one of the most important and promising transfer information technologies given its intrinsic advantages of long-range mobile communication, cost-effectiveness of multicast and broadcast systems, wide coverage area, and high flexibility. Satellite communications systems enable the sending and receiving of information worldwide, offering internet access, television, telephone, radio, and other civilian and military operations, the satellite network communication framework structure is shown in FIGURE. 1. The advent of HTS (high-throughput satellite) systems has greatly enhanced technical capabilities and offered wideband services at lower costs. Significant improvements are expected on the forthcoming mega-constellations in low Earth orbits that will deploy thousands of satellites, providing full earth coverage to minimize delays in addition to wide bandwidth. The use of satellites, given these characteristics, can increase efficiency in providing large sets of services and applications that are security-sensitive, such as telemedicine, banking, search and rescue, sensor networks, and content delivery network feed, which generate approximately 90% of the total traffic. However, in many cases, the security of satellite communication has been seriously compromised, resulting in covert dangers [1]. In satellite communications (and even in

In wireless sensor networks (WSN), data aggregation is a widely used method. Security issues like data integrity and data confidentiality became a significant concern in data aggregation when the sensor network is deployed in a hostile environment. Many researches may carry out several works to tolerate these security issues. However, there were some limitations like delay, the arrival rate of packets, and so on. Hence, to overcome the existing problems, this approach offers a blockchain-dependent data aggregation scheme in WSN. The main intention of the proposed work is to generate a certificateless key generation so that the proposed system's secrecy rate is improved. The use of blockchain is employed for security purposes, and it enables the user to acquire the information stored internally in an effortless manner. Initially, deployment of sensor and base station (BS) is carried out, followed by node registration at which the public/private keys are generated. The computation of private hash values is carried by performing certificateless key generation. After that, the formation of blockchain is made using the PoW (Proof of Work) detection algorithm followed by the aggregation of data. In the data aggregation process, Elgammal based cryptographic approach is introduced to acquire member data, perform aggregation logic, and transfer the aggregated data. Finally, cluster-based routing is established with the use of Knapsack based cluster routing strategy. The performance investigation of the proposed system is estimated and the outcomes attained are compared with the existing techniques in terms of arrival rate, average delay, and the delay ratio of the packets. The investigation illustrates that the suggested approach is better than the traditional techniques.
