Abstract
The present disclosure relates to the use of cryptographic techniques to facilitate local decision making at a gateway device () interfacing between an operator device () and edge devices (), for example as can be found in Internet of Things infrastructures. Local decision making is facilitated in the context of end to end encryption of data between the edge device and operator device by enabling a function of the data to be computed at the gateway () without decrypting the data, for example using Functional Encryption (FE). The gateway determines an action based on the computed function, for example whether to transmit the data to the operator device (). Examples of edge devices are video surveillance cameras or utility consumption meters but the disclosure is applicable to any edge device that produces data to be transmitted with end to end encryption. The disclosure is also not limited to IoT infrastructures.
