Why do we want an PBC/IBE Standard?
•
Prevent incompatible implementations
•
•
To get the design right and prevent mistakes
•
•
Peer review on algorithms, implementations,
parameter selection
Establish credibility for PBC/IBE
•

Don’t want to repeat S/MIME vs. PGP vs.
other
Everyone in this room knows that it is real,
many people outside this room don’t
Standards Philosophy
• Model after past IEEE cryptographic standards
• Standardize algorithms, but not protocols
• e.g. formats for IBE encrypted email would be part
of a different standard
• Don’t block future standards based on PBC
• Allow for amendments that build on parts of this
standard
• Separate IBE and PBC layers
• Limit scope to keep the task manageable
• Goal is to have a standard relatively soon
• Focus on one set of algorithms, split off other
types of algorithms into separate standards

Pairing Based Crypto Layer and Algorithm Layers
IBE based Protocols
e.g. IBE email, key request etc.
Identity-Based Encryption
Definitions of algorithms
