eTrustworthiness of a software system is an NFR that has become of prime importance in the modern distributed and decentralized systems. Trustworthiness can be regarded as a combination of other NFRs such security, dependability, reli-ability, and so on. We should emphasize that trust is a much broader issue than just security [2]. A system can be secure but still not trustworthy if it cannot recover from failures or is not reliable in producing results. A trusted system has been described as one that is responsible for enforcing security, and consequently the security of the system depends on its flawless operation [3]. In an idealized scenario, a trustworthy system is one on which the user(s) can completely rely. It would be secure, reliable, dependable and robust, and at the same time research literature is almost completely devoid of the relation-ship of key architectural dimensions (software components, connectors, and configurations [10]) to a system’s trustworthi-ness. This paper presents an initial study targeted at relating a soft-ware system’s architecture and its trustworthiness. In support of this, we identify a set of trustworthiness dimensions and briefly survey how they have been addressed in existing research. In the process, we argue that “trustworthiness ” is a more broadly encompassing term than the more frequently used “security”, and that the two are closely interrelated. Finally, we try to relate, and study the impact of, the dimen-sions of trustworthiness to those of software architectures.Leveraging Architec
