DESCRIPTION
Presentation done at the Research Brazil Ireland (RBI) event in São Paulo. RBI brings together Irish third-level institutions and research centres as a consortium—at national level—to drive a coordinated national approach to promote Ireland´s scientific and technological reputation in Brazil and to highlight Ireland’s attractiveness as an international research partner. The Irish Minister for Education and Skills, Ruairí Quinn T.D., will be the keynote speaker to be followed by eminent Irish and Brazilian researchers showcasing successful collaborative projects to-date in the fields of Science and Engineering. This will be an important opportunity to learn about research developments in Ireland and Brazil and how European funding through the EU Horizon 2020 programme can be leveraged by Brazilian and Irish researchers. All participants will be invited to an informal networking event in the evening, organized by Enterprise Ireland. Facilities will be on offer on the morning of October 22 for continued collaborative discussions between Irish and Brazilian researchers.

“Clean slate” architecture to the new new generation of converging information technologies.
Distributed systems cooperate each other towards self-organizingall architectural functionalities.
Employs a bottom-up approach where complex distributed systems are formed by the cooperation of simple ones.
Complex protocols like TCP are fragmented on a population of cooperating services - combined at runtime.
The main novelty is on how the Future Internet ingredients are integrated.
NovaGenesis Overview (1/4)
Entities and content naming employs natural language and self-certifiable names (hash codes).
All functionalities are seen as services, including network protocols.
Name bindings are stored on distributed hash tables, representing all kind of relationships among named-things.
Name bindings are published and subscribed, enabling distributed search, discovery, negotiation, and contracting of services and content.
NovaGenesis Overview (2/4)
Substrate resources are exposed to software by proxies, which represent them regarding resource life-cycling and orchestration.
All the communication is done by message scheduling and exchanging, with dynamic headers.
All the service contracts can capture intrinsically the required quality, security, privacy, reputation, etc.
The services will employ a decision cycle to meet objectives traced by human and machine operators.
They compete each other to better satisfy contracts (evolutionary pressures) and optimize the usage of substrate resources (evolution environment).
NovaGenesis Overview (3/4)
NovaGenesis Overview (4/4)
Requirements and challenges:
- Message/data integrity and confidentiality.
- Rendezvous among publishers and subscribers.
- Security, privacy, and trust of entities/content life-cycling.
- Trust network formation, assertion, and management.
- Identity, privacy, and reputation management.
- Unbiased contract, reputation, and trust evaluation.
- Build-in police definition, enforcement, and conflict resolution.
- History preservation versus cleaning.
- Revoking of published bindings, data, permissions, etc.
Security Aspects (1/2)
Requirements and challenges (continuing):
- Distributed key generation and cryptography.
- Voting and coordination of entities towards social security.
- Distributed/hierarchical certification chains.
- Management of different hash algorithms and sizes.
- Deterministic building of binary executables.
- Management of copies and clones.
- Scalability, resilience, “on the fly” algorithm changing.
