On the construction of a leakage-resilient certificate-based encryption with equality test scheme

This academic paper, published in June 2026, presents a new encryption method that combines certificate-based encryption (a system where a trusted authority issues certificates to verify identities) with equality test capabilities (the ability to check if two encrypted messages contain the same data without decrypting them). The scheme is designed to be leakage-resilient, meaning it can still protect data even if some secret information is accidentally exposed to attackers.
