Privacy-Preserving Proxy Bilateral Access Control for Secure Data Forwarding
- Published
- Record updated
Summary
The authors propose a privacy-preserving proxy bilateral access control scheme for secure data forwarding. Proxy re-encryption alone lets only the data owner set who can decrypt, and forwarding through multiple nodes exposes data to impersonation and forgery. The scheme lets both sender and receiver state access policies, and the authors prove message confidentiality and authenticity under standard assumptions in the random oracle model.
