  1. Dependable TechnologiesVerification & Validation (DeFINE) Ana CAVALLI INT- Evry France

  2. MOTIVATION • Why verification and validation are crucial dependable technologies ? • Dependability has as main objectives: availability, reliability, survivability, safety, security... • To achieve these objectives it is necessary to use methods for • System design • Verification • Validation (testing)

  3. VERIFICATION & VALIDATION • What is verification? • Verification: To check that the system specification is correct and does not contain errors • What is validation? • Validation (testing): To check that the system implementation possesses the expected properties and does not contains errors (also to check interoperability with other implementations or other components)

  4. VERIFICATION • Based on • formal specifications • static analysis techniques • model checking • To verify • global properties • component properties • To detect • design errors • deadlocks, livelocks

  5. VALIDATION (testing) • Based on • formal specifications • active testing techniques (test generation, test selection, test execution) • passive (monitoring) testing techniques • definition of new architectures (for instance to test embedded systems) • fault models definition (to help define coverage and to detect errors) • coverage measures • To perform • component testing • integration testing • interoperability testing • load testing • robustness testing • To detect • functional errors • structural errors • transmission errors

  6. HUMAN FACTOR IN SOFTWARE DESIGN • Combining both verification and validation techniques to be applied on system human interaction • to anticipate user behaviour (automation surprises, particularly in critical situations) • to specify stress environments • to produce scenarios that may identify potential automation surprises

  7. GOALS • Adaptation of these techniques to dependable embedded systems. For instance, to be applied to: • fault tolerant architectures • cryptography, security protocols • real time constraints • Use of software tools • for the application to real systems • to assure scalability of methods • Integration in platforms to cover verification and validation (testing) of dependable systems

  8. APPLICATION DOMAINS • Telecommunication systems • Cellular and wireless networks • Communication protocols • Ad-hoc services and networks • Rescue, emergency, military, ... • Embedded systems • Transportation systems (air and ground) • Smart highways, automatic driving devices • Devices for helping handicapped persons

  9. WORKING GROUPS • WG1:Verification and validation methodologies for dependable embedded systems • WG2: New validation architectures for dependable embedded systems • WG3:Monitoring dependability measures • WG5: Formal aspects of user behaviour in safety critical environments. • WG6: Platforms for verification and validation of dependable industrial applications (cellular and wireless networks, ground and air transportation).

  10. CROSS ACTIONS • Roadmap for verification and validation of dependable embedded systems: A strategy for research and development • Education and training: Creation of Pan-European masters as well as a common Doctoral program • Elaborate best practices • Participation in the definition of standards: ETSI, ISO, ITU-T, OMG, IETF, etc. • Promotion of common activities with enterprises: IP projects, national projects
