Digital Trust - Trusted Computing and Beyond: A Position Paper

Abstract

Abstract-Along with the invention of computers and interconnected networks, physical societal notions like security, trust, and privacy entered the digital environment. The concept of digital environments begins with the trust (established in the real world) in the organisation/individual that manages the digital resources. This concept evolved to deal with the rapid growth of the Internet, where it became impractical for entities to have prior offline (real world) trust. The evolution of digital trust took diverse approaches and now trust is defined and understood differently across heterogeneous domains. This paper looks at digital trust from the point of view of security and examines how valid trust approaches from other domains are now making their way into secure computing. The paper also revisits and analyses the Trusted Platform Module (TPM) along with associated technologies and their relevance in the changing landscape. We especially focus on the domains of cloud computing, mobile computing and cyber-physical systems. In addition, the paper also explores our proposals that are competing with and extending the traditional functionality of TPM specifications.

Smart Home Devices: Promoting User Trust and Protecting User Data

“…They felt as if their physiological integrity was compromised because the telephone seemed to break down the walls between the public and private sphere, making them feel as if they were never truly alone even in their personal space (Rymarczuk, 2016). Because mistrust of new technology is seen even in contemporary times, there is a need to create trust between users and technology in the form of digital trust in order for new technology to be accepted by society as a whole (Akram & Ko, 2014).…”

“…Smart home systems usually consists of sensors, monitors and devices that communicate with one another to automate and control the home environment (Chifor et al, 2018;Mocrii et al, 2018;Shin et al, 2018;Silva et al, 2012;Wilson et al, 2017;Akram & Ko, 2014). Mocrii et al (2018) note that smart homes are not "automated" systems but rather "intelligent ones" because they encompass the bigger picture and can make predictions based on previous knowledge.…”

“…The IoT is made up of an interconnected network of devices with limited computing capabilities that have a cloud component to process data and send data to the users (Anthi, Ahmad, Rana, Theodorakopoulos, & Burnap, 2018;Chifor et al, 2018;Mocrii et al, 2018). Cloud technology makes SHT scalable and flexible, but because this technology is usually offered by third parties, it is less secure because data storage and processing is done off-site (Akram & Ko, 2014).…”

“…Yan, Kantola, & Zhang (2011) states that trust allows us to act under uncertainty. Looking at trust between humans and devices, Akram & Ko (2014) defines digital trust as "a trust based either on past experience or evidence that an entity has behaved and/or will behave in accordance with the self-stated behaviour." Through all of these definitions and conditions of trust, we can conclude that creating trust between users and machines happens over time through interacting with a product.…”

User-Centered Attestation for Layered and Decentralised Systems

“…The TCG coined term and the architecture itself is rather vague but decisively extends the adjective trusted, which should cause curiosity since intuitively only the TPM [11] should be trusted but not the entire platform. Recently, Akram et al [1] have adopted the term in a position paper on digital trust as their vision for trusted cloud computing using the architecture in Fig. 1.…”
