Concealing Complex Policies with Hidden Credentials
Abstract
Hidden credentials are useful in protecting sensitive resource requests, resources, policies and credentials. We propose a significant improvement in decryption performance when implementing hidden credentials using the Franklin/Boneh IBE. We also propose a substantially improved secret splitting scheme for enforcing complex policies, and show how it improves concealment of policies from nonsatisfying recipients.
