HERACLEIA Security ProjectsOpen Collaboration System:How can we enable any entity to join a collaboration group

in a P2P environment? Entities can log on to system with any names they want. Collaborative groups can be created by any entity and share

files in a P2P fashion. Our OC System supports operations on groups, roles and

shared files.

Certified Authority Project: Short-lived certificates(SLC) are used to prevent unofficial information propagation which

can take place due to various causes We use forward secure signatures in SLCs and cut off the cost for the revocation.

Fall 2007 51

HERACLEIA Sensor Localization ProjectsGeographical Distributed

Localization (GDL) : Localization is a fundamental

Problem in Wireless Sensor Networks.

Our GDL protocols support both static and mobile node localization

We use a novel computational model for localization.

Wormhole Detection Project: How can we protect Wireless

Sensor Networks in hostile environments?

We have developed a distributed wormhole detection algorithm based on static GDL to detect as well as locate wormholes inside the network.

Fall 2007 52

HERACLEIA Location Privacy ProjectsLocation privacy in sensor

networks: How can we protect the

location privacy of the sources of messages in a sensor network?

We create routing traps to confuse the attackers.

Sensor network anonymity project:

Location sensors can be attached to people’s cell phone and medical sensors can be attached to human body to monitor vital signs.

In such sensor networks, anonymity of participants needs to be protected.

We use one-way hash chains to refresh IDs of sensor nodes.
