  1. Annual review ROME 2012 WP4 - Network

  2. Work package - objectives • Task 4.1 Smart SPD driven transmission • SE; SG; THYIA; TUC; UNIGE • Task 4.2 Distributed self-x models • ATHENA; THYIA, TUC, UNIGE, UNIUD, SE • Task 4.3 Reputation-based resource management technologies • HAI; SE, TECNALIA, INDRA, MGEP, TUC, UNIROMA1 • Task 4.4 Trusted and dependable Connectivity • ISL; SE, SCOM, TECNALIA, HAI, MGEP, THYIA, TUC

  3. Smart SPD-driven transmission • Goal: providingreliable and efficient communications even in critical (physical) channel conditions • Adaptive and flexible algorithms for dynamically configuring and adapting various transmission-related parameters • Based on the Software Defined Radio (SDR) or Cognitive Radio (CR) technology • Shall be SCA-compliant • Security-aware framework • Deployment ofdifferent state-of-the-art technologies for detecting and countering reconfigurability-related and cognitive capability-related security issues and attacks

  4. Smart SPD-driven transmission (2) Software Communications Architecture (source: SCA 4.0 specification)

  5. Smart SPD-driven transmission (3) Security-aware framework (source: nSHIELD deliverable 2.4)

  6. Smart SPD-driven transmission (4) Trusted Network Routing Service (source: nSHIELD deliverable 2.4)

  7. Distributed self-x models • Goal: Providing network transmission technologies to support the dependable self-x technologies at the node level by means of Cognitive Radio technologies • Self-x refers to: • Self-(re)configuration • Self-management • Self-supervision • Self-recovery • Evaluation of risks has been performed so far, with the following types of attacks identified and analyzed: • Side channel attacks • Denial-of-Service (DoS) attacks

  8. Reputation-based resource management technologies • Goal: Using information of nodes’ past behaviours in order to estimate the current trustworthiness level • Reputation and trust based Intrusion Detection Systems for WSN • New distributed approach (vs. centralized in pSHIELD) • Agent based detection minimises the communication needs • Both anomaly and specification-based detection • Anomaly detection using a simpler model (to reduce CPU and power consumption) • Coupled with specification based detection to enhance efficiency

  9. Reputation-based resource management technologies (2) • Distributed detection • Node monitors local activities • If not sure about nature of an activity, node contacts other nodes in the neighbourhood • Reputation and trust of node set according to local and neighbour information • When anomalous activities are flagged locally, this information is broadcasted to the rest of nodes

  10. Trusted and dependable connectivity • Goal: assuring communicationsintegrity to the maximum possible extent • Regarded at two levels: • Trusted Network Routing Service • Possibility of choosing between different routing schemes, based on the input of the reputation-based scheme • Secure Data Exchange/Communication Service • Encryption schemes to enable protection (and integrity) of data • CRC encoding and checksum techniques to verify data integrity • Authentication schemes to verify identity of sender/receiver

  11. Applications and scenarios • AirBand - group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation • ESs are usedtoperformthecommunications, forexample, VOR uses radio beacons • nSHIELD couldbe usedbyalltheapplicationsusingAirbandfrequencies (VOR, ATIS, ASOS, ILS…) toprovide SPD capabilities in theircommunications • GSM-R - network for railway communication based on GSM technology but uses specific frequency spectrum • Already has several SPD featuresimplemented, such as: • Availabilityrequirement using full redundancy of radio coverage and all network elements • Securityand integrity requirements encrypting the information (a Key Management Service distributes encryptationkeys) • Security measures inheritedfrom GSM techonology

  12. Applications and scenarios (2) • Machine Redable Travel Documents (MRTD) – travel documents equipped with a smart card processor to perform biometric identification (face identification) of the holder • The new passport design is intended to serve two purposes: • The biometric information can be used to verify the identity in the border control • Cryptographic technologies can be used to ascertain the integrity and originality of passports, thus preventing high quality passport forgeries

  13. Contributions • Marko Cesena – SELEX ELSAG • Krešimir Dabčević, Lucio Marcenaro – UNIVERSITY OF GENOVA • InakiEguia Elejabarrieta – TECNALIA • Barri Vilardell, Ignasi Oriol – INDRA • Andreas Papalambrou – ATHENA/ISI • Roberto Uribeetxeberria - MONDRAGON UNIVERSITY • Alex Papanikolaou – TECHNICAL UNIVERSITY OF CRETE

  14. The END That’s all folks!
