2. Technology Hype
We live in a world embedded with small devices, with computing and communication capabilities.
These devices are:
ubiquitous;
Mobile: Portable, handheld, wearable;
Small size: from our cell phone to a few squared millimiters;
Heterogeneous.

3. Characterization
Features:
Communication capabilities;
Cooperation (e.g. self-organizing);
Service Advertising;
Proxy.
Constraints:
Energy supply (Battery powered);
Hardware resources (memory, processor capab.);
Communication channels (error prone);
Limited bandwidth.

4. Security as a pre-requisite for Dependability
Security Features:
Authentication;
Confidentiality and Integrity for:
Group communications;
pair wise communications,
Availability of services: e.g. regardless of devices constraints we want to provide secure seamless access to data.

5. Constraints Efficient management of membership changes;
Meet exposed constraints:
Energy supply (Battery powered);
Hardware resources (memory, processor capab.);
Communication channels (error prone);
Limited bandwidth.

6. Privacy open issues
Management of the always on-line/always traceable paradigm;
Management of multiple identities;
Boundaries to Data migration;
Boundaries to Data collection.

7. Concluding Remarks Security and privacy in the wireless environment:
Enabling factors for the fostering of the mobile e-world;
Tightly coupled with dependability: main obstacle, if not addressed, to the future of the mobile e-world.
