Presentation done at the BIC event at São Paulo, 2013. As part of it’s long term strategy for building international cooperation, the BIC project is setting up an in-country Extended Working Group (EWG) in Brazil comprised of key members of the Brazilian research community engaged in research in all areas related to Trustworthy ICT and international cooperation. The launch meeting of the Brazil EWG was held on 22nd October, 2013, at the Instituto de Tecnologia de Software (ITS) in São Paulo, Brazil.

3. Very Brief History
‣ 2008: Started Future Internet activities @ Inatel.
‣ 2009: Studying.
‣ 2010: First NovaGenesis design principles and choices.
‣ 2011: Finished draft architecture.
‣ 2012: Started proof-of-concept implementation. Refinement of
choices.
‣ 2013: Test scenario over Mobile Future Internet (MOFI) from
ETRI, CNU, and KNU - South Korea.

4. NovaGenesis Overview




Entities and content naming employs natural language and selfcertifiable 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.

5. NovaGenesis Overview





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).

8. Testing Scenario: Joint Services and Content Orchestration
‣ Clients e servers discover each other, publish SLAs and
exchange named-content based on user policies.
‣ Provides check for content provenance, integrity, and coherence
of content.
‣ MOFI provided transparent connectivity change.

9. Testing Scenario: Joint Services and Content Orchestration
‣ Content publishing round trip time
‣ Content subscription round trip time

10. Security Aspects

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.

11. Security Aspects

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.

12. Of course, we are looking for collaboration to
address these challenges on Future Internet!
Thank you!
