Trusted Communication in the Internet of Things: Applications of Blockchain and Quantum Technology

The rapid expansion and inherent resource limitations of Internet of Things (IoT) devices necessitate robust, future-proof security solutions, particularly against sophisticated data integrity threats and the imminent risk of quantum computing attacks. This paper provides a systematic literature review (SLR) of the architectural integration of blockchain with quantum technologies (quantum key distribution (QKD) and post-quantum cryptography (PQC)) for a two-stage trust model in IoT communication. This review summarizes existing methods and answers three key research questions. Permissioned blockchains primarily serve the purpose of trust management, ensuring the non-repudiation and immutability of data. Notably, there is a clear distinction in the application of quantum solutions: QKD is particularly well-suited for securing high-capacity backbone communications (server gateways), while PQC (especially lattice-based algorithms such as Kyber and Dilithium) is the most resource-efficient solution for IoT terminals. However, this integration also has significant drawbacks, such as high latency due to blockchain consensus mechanisms and increased memory and CPU requirements from PQC implementations. The main challenge is the lack of standardized protocols for integrating QKD key management with smart contract functionality. This review provides a comprehensive analysis of current architectures, assesses their performance trade-offs, and outlines a clear research agenda aimed at developing standardized hybrid protocols for future trusted IoT systems and optimizing resource-efficient, quantum-resistant consensus mechanisms.

Optimizing Radio Broadcasting in the Digital Age: Effective Planning and Management Strategies

In the contemporary digital era, radio stations are confronted with novel challenges and opportunities that require more effective planning and management strategies. This study explored the significance of comprehensive planning and management in optimising radio broadcasting, particularly in the context of evolving technology and shifting audience preferences. Through an analysis of case studies and current research, this study identifies the key components of broadcast management planning, including programming strategy, resource management, and budget management. In addition, it examines the challenges confronting radio stations in the digital age, such as their adaptation to new technologies, industry competition, and evolving audience preferences. Adopting a holistic stance, this study proffers pragmatic recommendations for radio stations to enhance their operational efficiency, content quality, and audience engagement. The findings of this study are anticipated to provide guidance to broadcasting professionals, enabling them to plan and manage their operations more efficaciously in the digital era.

Rediscovering Relevance: The Key Role of Websites in Maintaining Radio Station Popularity

 

In the age of algorithmic hegemony, traditional radio must contend with competition from music streaming services and independent podcasts. To survive and remain relevant, radio must conduct digital transformation by surfing on the wave of the Internet, and websites serve as the “anchor.” This study examines the extent to which websites promote and sustain radio stations. It focuses on three metropolitan stations in Indonesia: Sonora FM Jakarta, PRFM Bandung, and Suara Surabaya. Using a qualitative case study approach, data were collected with in-depth interviews with station managers, digital ethnography in a professional forum (FDR Indonesia), and content analysis of the stations’ digital properties. The study found that the website is not merely an option but a required “digital face” that enables a supportive symbiosis across platforms. By adding streaming radio, news archives, and podcasts on demand, stations turn passive audience members into active interactors. In conclusion, a radio station can best maintain its public and brand image by providing nonlinear material and hypermedia experience through a robust website.
