We present new constructions of multi-input functional encryption (MIFE) schemes for the inner-product functionality that improve the state of the art solution of Abdalla et al. (Eurocrypt 2017) in two main directions. First, we put forward a novel methodology to convert single-input functional ...
Multi-Input Functional EncryptionConsider sources that supply sensitive data to an aggregator. Standard encryption only hides the data from eavesdroppers, but using specialized encryption one can hope to hide the data (to the extent possible) from the aggregator itself. For flexibility and security, ...

Multi-input functional encryption (MIFE) was introduced by Goldwasser et al. (EUROCRYPT 2014) as a compelling extension of functional encryption. In MIFE, a receiver is able to compute a joint function of multiple, independently encrypted plaintexts. Goldwasser et al. (EUROCRYPT 2014) show variou...
The notion of multi-input functional encryption (MI-FE) was recently introduced by Goldwasser et al. [EUROCRYPT'14] as a means to non-interactively compute aggregate information on the joint private dDOI: 10.1007/978-3-662-48797-6_2 被...
We construct a general-purpose multi-input functional encryption scheme in the private-key setting. Namely, we construct a scheme where a functional key corresponding to a function f enables a user holding encryptions of x1, . . . , xt to compute f (x1, . . . , xt) but nothing else...
Multi-input Functional Encryption We introduce the problem of Multi-Input Functional Encryption, where a secret key sk f can correspond to an n -ary function f that takes multiple ciphertexts as input. We formulate both indistinguishability-based and simulation-based def... S Goldwasser,SD Gordon...
