Trust and Indra

• Cryptographic primitives:

  • Public key cryptography for both security and authentication
  • Indra daemons identified by unique keys generated by admin
  • Security layer encapsulates cryptographic functions

• Cryptographic primitives:

  • Depends on central key server to certify public keys
  • Existing PGP key server network may be used
  • Does not scale well with number of nodes

• “Web of trust” model:

  • Certain nodes have pre-assigned trust
  • Trust for new nodes computed using transitive trust relations
  • Heuristics like “maximum flow” may be used
