Abstract: International audience; Multi-input functional encryption is a paradigm that allows an authorized user to compute a certain function-and nothing moreover multiple plaintexts given only their encryption. The particular case of two-input functional encryption has very exciting applications, including comparing the relative order of two plaintexts from their encrypted form (order-revealing encryption). While being extensively studied, multi-input functional encryption is not ready for a practical deployment, mainly for two reasons. First, known co...
