Thinking about Privacy and Security in a Mobile Virtual Internet for the MIT Community

Draft
May 2007

2. A Mobile Architecture for MIT Community
Make networks that support mobile community members interoperable at the right functional level
Multiconnected
User centered
Application spans heterogeneous technology

3. Attributes of Network Mobility: devices move (frequently, not rapidly)
Awareness: devices can sense, and adapt
Accomodating: environment accomodates new devices
Transport independent: minimize dependency on specialized transport networks

4. Concerns to ensure Heterogeneous in function
Heterogeneous in implementation
Evolvable/futureproof
Composable devices/functions/...
Safe and respectful (rather than security)
Sharing is controlled

5. Enhancing WLANs No “association delay”
Standardized position sensing and presence sensing
Beyond “service discovery”

6. Enhancing “cellular data networks”
Build on MVNO concept
Home Location Registry and AAA/AN services provided by MIT in concert with a cellular provider
New protocol layers that support awareness, multiconnected devices, transport independence, event distribution

7. Enhanced Identity and Authorization
Put user in control of negotiated authorization to access network resources
Support multiple identities, temporary identities, agency relationships

8. Enhanced coordination protocols
Many events are of interest to a variety of devices, based on context
Network exists to distribute event notifications
Internetworked publish subscribe protocols: event = {producer, topic, consumer, timestamp, message} [where producer, topic, consumer are unique Ids or names]

9. Privacy and Security
Personal privacy in a network of shared sensors, shared events and shared context
Protection from harassment, stalking
Protection of underlay infrastructure
Protection from “leakage”
Non-discretionary agency

10. Value of traditional COMSEC
Document focused – but what are the documents?
Resource focused – but applications span resources routinely
Topology based – but we share a common world

11. Need to invent a new framework
Need rich agency infrastructure (beyond Federated Identity)
Use context and sensor information as part of decisions
Safety is a larger term than security
Negotiation
