Multi-Client Functional Encryption with Public Inputs and Strong Security

ePrint Report: Multi-Client Functional Encryption with Public Inputs and Strong Security

Ky Nguyen, Duong Hieu Phan, David Pointcheval

Recent years have witnessed a significant development for functional encryption (FE) in the multi-user setting, particularly with multi-client functional encryption (MCFE). The challenge becomes more important when combined with access control, such as attribute-based encryption (ABE), which was actually not covered by the FE and MCFE frameworks. On the other hand, as for complex primitives, many works have studied the admissibility of …
