“…o‐PUF implementations are based on the combination of the coherent interaction of a laser beam with the randomness of a disordered physical medium. The medium could be a material containing randomly positioned micro‐structures that act as scatterers [2, 34], a sheet of regular paper [35], or an optical fibre [6, 36]. A laser source illuminates a transparent, inhomogeneous medium (PUF's token), the goal being to produce unique interference patterns (speckle) which are subsequently captured as images (responses).…”

“…In o‐PUF implementations, a number of the coherent light source parameters can be varied in order to create different challenges [34], such as the angle and number of incident beam(s), their wavelength [6, 36], the beam(s) diameter, the beam's spatial intensity profile etc. In this set‐up, the different challenges are created by varying the laser beam's spatial intensity profile, using the LCD screen.…”

“…To make matters worse, their quality is proportional to their size and price; the same applies for efficient true random generators. As shown in [6], optical PUFs (o‐PUFs) can be successfully employed as random number generators with performance proven using the NIST random number evaluation test suite and minimum entropy calculations. The generated bit‐strings can be used as symmetric keys or as random seeds for a pseudo‐random generator with no additional processing.…”

In an environment where cyber attacks are increasing, both in frequency and complexity, novel ways to shield data, users, and procedures have to be envisioned. Physical unclonable functions (PUFs) are the physical equivalent of one-way mathematical transformations with the exception that their inherent physical complexity renders them resilient to cloning. One interesting deployment scenario includes PUFs as random key generators. The deterministic nature of their operation alleviates the necessity to store the keys in non-volatile means. Along the same lines, blockchain is inherently resistant to modification of the data once stored while their overall security depends on the quality and secrecy of users' keys. Here, the authors propose a novel optical PUF implementation that can be combined with private blockchain modalities in order to cyber-harden Internet of things ecosystems. PUF-related experimental results are presented, alongside implementation scenarios.

“…eHealth research projects are conducted by large consortia formed of public-private partnerships that operate in multinational settings that are increasingly attempting to bring together large data sets utilising patient's computerised medical record data for cross-border applications. The EU-funded KONFIDO project (http:// konfidoproject.eu/) [8][9][10] presented in the present volume [7], aims to develop tools and procedures to create a scalable and holistic paradigm for secure inner and crossborder exchange of healthcare data in a legal and ethical way at both national and European level. KONFIDO requires assessing the ethical dimensions that concerns the collection, storage, transmission and dissemination of personal data.…”

Innovative eHealth technologies and solutions are changing the way healthcare is delivered, raising many challenges regarding the ethical concerns that need to be addressed. There is a growing demand for tools that enable the assessments of the ethical impact in order to assure compatibility or highlight areas of incompatibility. This paper aims to address the ethical challenges that will arise during KONFIDO EU-funded project. KONFIDO project aims to develop tools and procedures to create a paradigm for secure inner and cross-border exchange of healthcare data in a legal and ethical way at both national and European level. The paper proposes an ethical framework that consists of a set of ethical principles derived from recent literature and European regulation and a supporting checklist. The ethical framework represents a concrete and practical guidance for healthcare professionals and developers in order to build ethically acceptable KONFIDO solutions.

Allowing cross-border health-care data exchange by establishing a uniform QoS level of health-care systems across European states, represents one of the current main goals of the European Commission. For this purpose epSOS project was funded with the objective to overcome interoperability issues in patients health information exchange among European healthcare systems. A main achievement of the project was the OpenNCP platform. Settled over the results of the epSOS project, KONFIDO aims at increasing trust and security of eHealth data exchange by adopting a holistic approach, as well as at increasing awareness of security issues among the healthcare community. In this light, the paper describes the KONFIDO project's approach and discusses its design and its representation as a system of interacting agents. It finally discusses the deployment of the provided platform.
