Sustainability perspectives towards distributed MIMO for 6G systems

Speaker: Sara Willhammar, EIT

Abstract: This talk presents early results of an exploratory work and a high-level conceptual framework aiming at providing a structured way of how to qualitatively integrate sustainability perspectives in technology development. We analyze aspects of 6G systems in terms of environmental, social and economic sustainability, from the dimensions of ?sustainable 6G? and ?6G for sustainability?. This sustainability framework is then applied to distributed MIMO, one of the candidate technologies for 6G, to outline challenges and opportunities that should be considered in the development of the technology to be used for 6G systems. 

Speaker Bio: Sara Willhammar is a Postdoc at the Department of Electrical and Information Technology at Lund University, Sweden. She received her dual Ph.D. degree in Electrical Engineering from Lund University, Sweden and KU Leuven, Belgium in 2022, and her M.Sc. degree in Electrical Engineering from Lund University, Sweden, in 2017. Her research interests are within channel measurements, characterization and modeling for next generation wireless systems. She also has an interest in the broader field of wireless communication in terms of exploring sustainability perspectives in the development of such systems.

Trusted Third Parties (TTPs) are a standard building block in secure systems and are used in many cryptographic protocols. A TTP is an entity which facilitates interaction between the users in a system. As the name suggests, TTPs are trusted, and can thus be relied on to perform critical parts of a protocol without need for external scrutiny. Due to this property, they can serve the role of making protocols easier to design, maintain and participate in.

Since TTPs are trusted, they often have access to some of the most sensitive information in a system; e.g., in backup systems, or when used for privileged roles such as certificate authorities. If a TTP is not as trustworthy as assumed, the consequences can be severe. This is often the case in practice, where multiple examples of failures among high-profile TTPs exist. For example, data leaks are common news and certificate authorities have been caught issuing incorrect certificates. This illustrates the problem that the trustworthiness of a TTP is often more of a convenient assumption than a system property motivated by properly investigated system mechanisms.
