Abstract

Torus Fully Homomorphic Encryption (TFHE) is a probabilistic cryptosytem over the real torus which allows one to operate directly on encrypted data without first decrypting them. We present an aggregation protocol based on a variant of TFHE for computing the sum of sensitive data, working only with the corresponding ciphertexts. Our scheme is an ideal choice for a system of smart meters - electronic devices for measuring energy consumption - that demands consumers’ privacy. In contrast to some other solutions, our proposal does not require any communication among smart meters and it is quantum-safe.
