The dynamic interaction and collaboration of the loosely coupled entities play a pivotal role for the successful implementation of a Digital Ecosystem environment. However, such interaction and collaboration can only be promoted when information and resources are effortlessly shared, accessed, and utilized by the interacting entities. A major requirement to promote an intensive sharing of resources is the ability to secure and uphold the confidentiality, integrity and non-repudiation of resources. This requirement is extremely important in particular when interactions with the unfamiliar entities occur frequently. In this paper, we present a distributed mechanism for improving resource protection in a Digital Ecosystem environment. This mechanism can be used not only for any secure and reliable transaction, but also for encouraging the collaborative efforts by the Digital Ecosystem community members to play a major role in securing the environment. Public Key Infrastructure is also employed to provide a strong protection for its access workflows.
