Confianza de grupo en sistemas distribuidos y sus relaciones con la seguridad de la información y la ciberseguridad

This thesis describes aspects regarding trust, reputation, information security and cyber security as connected subjects. It is the belief of this research that without trust it is not possible to address security in computational systems properly. One fundamental aspect is to use information system...

description This thesis describes aspects regarding trust, reputation, information security and cyber security as connected subjects. It is the belief of this research that without trust it is not possible to address security in computational systems properly. One fundamental aspect is to use information systems or to rely on them. One must trust the technology involved and consequently the entire system, without even knowing it in the rst place. Due to human characteristics, there is the tendency to trust that systems will keep our data secure. However, one basic problem is that trust and reputation deals with subjective evaluations. In many situations, information systems nowadays have distributed support. It means that there are a lot of parts that connect everything together, which is unknown to the ordinary users.
