Self-Processing Private Sensor Data via Garbled Encryption

Abstract: We introduce garbled encryption, a relaxation of secret-key multi-input functional encryption (MiFE) where a function key can be used to jointly compute upon only a particular subset of all possible tuples of ciphertexts. We construct garbled encryption for general functionalities based on one-way functions.We show that garbled encryption can be used to build a self-processing private sensor data system where after a one-time trusted setup phase, sensors deployed in the field can periodically broadcast encrypt… Show more

“…In the network environment, privacy is more a symbol of information and data, which can be used to confirm the identity and characteristics of specific individuals (or groups). But such information and data are sensitive content that individuals do not want to expose, such as patient data, personal location information, and financial status [3].…”
