HERACLEIA Security Projects

• Open 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.

23
HERACLEIA Sensor Localization Projects

• Geographical 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.

24
HERACLEIA Location Privacy Projects

• Location 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 peoples 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.

25
HERACLEIA Negotiation Projects

• SCENS Project
• SCENS (Secure Content Exchange Negotiation
  System) is a meta-data based negotiation system
  for agreeing data sharing conditions among
  parties who do not know each other. It can be
  accessed at
