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.

wormhole detection algorithm based
on static GDL to detect as well as
locate wormholes inside the
network.
