Spanish researchers have created real-life scenarios to assess the confidence of smart devices.
Researchers from the Network, Information and Computer Security Lab (NICS) group of the University of Málaga (UMA) have developed a computer system that establishes the necessary guidelines to build trust in the Internet of things, that is, for users to perceive the interactions between objects and people or directly between two objects as secure connections.
The experts have designed a framework composed of a set of tools and resources applicable to an operating system that allows Internet service developers to create reliable software applications.
The objective of this primary research study is to guide in the development of a concrete methodology to implant confidence and to make users feel more protected against the threats of the network, as informed by Fundación Descubre in a statement.
To do this, experts have developed generic software that can be adapted to any digital system and based on mathematical models that, depending on the case, use numeric calculation formulas or qualitative indicators.
“This type of connection is a further step towards the digitization of the physical world and must gather a series of guarantees that certify the security and privacy of its use, so as to generate models of trust that have been lacking until now,” he explained to the Foundation Discover the researcher of the University of Malaga and responsible for this study, Carmen Fernández-Gago.
Trust is a requirement that the user does not perceive, but is always evaluated. “In search engines for accommodation or hotel services, for example, they quantify this parameter through an internal system. In that case, the service that calculates the stars that a hotel or restaurant receives would be the service of trust. Mathematics or a qualitative algorithm that measures the degree of consumer satisfaction, “said the researcher.
The trust has evaluated it about two additional concepts: privacy and identity. “In the case of privacy, the more information is known about an entity to know it better and to be able to trust it, the more your privacy is violated, so an adequate balance between all these concepts is fundamental in the frame of reference that we propose, “he said.
Along with security, privacy, and identity, trust is an essential condition of the Internet of things. “Traditional security mechanisms,” he continued, “are not sufficient in a global system where data theft and the elimination of information is constant. However, trust management systems can help in these cases and ensure the success of this new Internet “.
All these proposals are published by the journal Information Sciences in the article entitled ‘Modeling trust dynamics in the Internet of Things,’ where the researchers also explain their studies on the current privacy problems of this technology. At the same time, they analyze the emergence and evolution of new privacy risks on the Internet.
