Trust Relationships

Protection is one of the key factors to be considered in application development. Every application should follow some security mechanisms to be free from fraudulent users. One of the important criteria to ensure security is Access control. [4]The reliability and security of the cloud and user are assured and effectively guaranteed during its interaction in the cloud computing environment. But these traditional models were unable to determine the vulnerability and ambiguity created by these open conditions. So the main focus throughout the evolution of new access control methods is on creating a mutual trust relationship between both interaction parties. The paper proposes a mutual access control model which is trust-based (MTBAC). Trust relationships between both interaction bodies are secured by mutual trust mechanisms. This model takes both the cloud service node’s trustworthiness and user’s action trust into consideration.

Enforcement and trust are opposite concepts in information security. This chapter reflects on the paradigm shift from traditional concepts of access control and policy enforcement toward de-centralised methods for establishing trust between loosely connected entities. By delegating parts of enforcement tasks to trusted elements dispersed in a system, the system can establish transitive trust relationships. This is the most advanced evolution of the organisational method of separation of duties within IT security. The technological basis for trust in systems – trusted computing platforms – is described on conceptual levels allowing comparison with other top-level security concepts and mapping to application domains. Important applications in modern information systems and networks are exhibited.

In the Qur'an we find different concepts of trust situated within different ethical discourses. A rather unambiguous ethico-religious discourse of the trust relationship between the believer and God can be seen embodied in conceptions of tawakkul. God is the absolute wakīl, the guardian, trustee or protector. Consequently He is the only holder of an all-encompassing trusteeship, and the normative claim upon the human being is to trust God unconditionally. There are however other, more polyvalent, conceptions of trust. The main discussion in this article evolves around the conceptions of trust as expressed in the polysemic notion of amāna, involving both trust relationships between God and man and inter-human trust relationships. This concept of trust involves both trusting and being trusted, although the strongest and most explicit normative claim put forward is on being trustworthy in terms of social ethics as well as in ethico-religious discourse. However, ‘trusting’ when it comes to fellow human beings is, as we shall see, framed in the Qur'an in less absolute terms, and conditioned by circumstantial factors; the Qur'anic antithesis to social trust is primarily betrayal, ‘khiyāna’, rather than mistrust.
