According to a study by the German Federal Printing Office (2022), every European lives with 90 digital identities on average, and the trend is rising. The German government has launched the innovation competition “Digital Identities Showcase” to select and promote identity projects for data security and sovereignty. The funding amount is 50 million EUR to develop software, research practical use cases and implement them by 2024. Of course, this large sum presupposes acceptance for the use of such digital identities, especially against the backdrop of critical opinions from the media and society, as already outlined in a Canadian study. However, there is little academic research on blockchain technology, but almost no article on the use of digital identities based on blockchain technology. This paper conducts a quantitative study on the social acceptance of digital identities using a questionnaire-based survey with 324 German participants on the social acceptance of the use of digital identities. The result of the study is that social acceptance of the use of digital identities is significantly influenced by demographics, citizens’ experience with blockchain products, affinity with financial products and privacy concerns.

Internet of Things connects the physical and cybernetic world. As such, security issues of IoT devices are especially damaging and need to be addressed. In this treatise, we overview current security issues of IoT with the perspective of future threats. We identify three main trends that need to be specifically addressed: security issues of the integration of IoT with cloud and blockchains, the rapid changes in cryptography due to quantum computing, and finally the rise of artificial intelligence and evolution methods in the scope of security of IoT. We give an overview of the identified threats and propose solutions for securing the IoT in the future.

“…This technique allows users to share information among nodes in the network that do not trust each other [ 12 ]. The attractive features of blockchain, such as transparency, privacy, and accountability [ 25 ], make it reliable for a variety of applications related to secure communication [ 9 , 26 ], smart contracts [ 27 ], healthcare [ 28 , 29 , 30 ], supply chain management [ 31 , 32 ], industries [ 33 ], and other financial services. Blockchain technology came to the mainstream with its most prominent application, namely the cryptocurrency Bitcoin [ 34 , 35 , 36 ].…”

The deployment of optical network infrastructure and development of new network services are growing rapidly for beyond 5/6G networks. However, optical networks are vulnerable to several types of security threats, such as single-point failure, wormhole attacks, and Sybil attacks. Since the uptake of e-commerce and e-services has seen an unprecedented surge in recent years, especially during the COVID-19 pandemic, the security of these transactions is essential. Blockchain is one of the most promising solutions because of its decentralized and distributed ledger technology, and has been employed to protect these transactions against such attacks. However, the security of blockchain relies on the computational complexity of certain mathematical functions, and because of the evolution of quantum computers, its security may be breached in real-time in the near future. Therefore, researchers are focusing on combining quantum key distribution (QKD) with blockchain to enhance blockchain network security. This new technology is known as quantum-secured blockchain. This article describes different attacks in optical networks and provides a solution to protect networks against security attacks by employing quantum-secured blockchain in optical networks. It provides a brief overview of blockchain technology with its security loopholes, and focuses on QKD, which makes blockchain technology more robust against quantum attacks. Next, the article provides a broad view of quantum-secured blockchain technology. It presents the network architecture for the future research and development of secure and trusted optical networks using quantum-secured blockchain. The article also highlights some research challenges and opportunities.
