This project aims at designing, implementing, and evaluating techniques to build autonomic Byzantine fault tolerant systems. This topic is of utmost relevance. Society depends more and more of internet based services that must be
protected from external attacks. There is anecdotical evidence that even non-critical systems, such as gaming platforms, may suffer severe attacks for almost frivolous reasons. For instance, in the recent Xmas of 2014, Playstation Online was unavailable for several days due to a denial of service which may have been associated with the release of a film (The Interview). Often, these attacks have severe consequences, such as leaking of confidential information, such as credit card information, clinical data, etc. Byzantine fault-tolerance can play a critical role in making these systems robust and adaptation is key to maintain the performance, respond to changes in the threat level, and to make attacks hardar (moving target defence). This project aims at contributing in this direction, by taking the following steps:
In summary, the major research results of the project will be:
