Privacy-Preserving Proxy Bilateral Access Control for Secure Data Forwarding

This research addresses limitations in proxy re-encryption (a technique that converts encrypted data so one user can decrypt it and another user can read it instead) by proposing a new system called privacy-preserving proxy bilateral access control. The new system allows both the sender and receiver to set rules about what data can be shared, while protecting the message from being read by unauthorized parties and from being altered or forged during forwarding through multiple nodes.
