Providing Security for Digital Ecosystems with Adaptative Encryption

One of the most important issues for digital ecosystems is the encryption of sensitive data across the different ecosystems, as the heterogeneity in their nature, capabilities and necessities make it very difficult to find a solution that may be applied to all of them. There are not proposals that suit these specific needs of digital ecosystems, especially the flexibility, required for defining adequate security policies and favouring secure information exchange. In this paper we show how adaptative encryption can provide digital ecosystems with a flexible, while secure, means for protecting information.
