ul-PCS

You can find the slides in this link.

Summary:

• We talked the importance of pro-active accountable privacy.
• The existing challenges and possible solutions.
• We discussed the syntax of unlinkable PCS.
• We discussed ul-PCS's applications and main building blocks.
• We talked about two more efficient instantiation than the generic model.
• We discussed the complexity of the proposed solutions.

Interesting Future Works:

• Minimize the needed trust to the central issuer.
• Design more efficient PO-PE which results to more efficient generic construction.
• Take a different approach with the same security properties.
