  1. 1. Homomorphic Encryption for Audio Conferencing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Herman Nordin; Ebba Lindström; [2022]
    Keywords : Homomorphic encryption; VoIP; security; audio conferencing; cryptography;

    Abstract : Homomorphic encryption (HE) enables computations on encrypted data making it possible to perform calculations on a server without sharing the secret key for decryption. HE is relatively new and has seen significant improvements in recent years in terms of speed of encryption, decryption, operations, and the number of operations possible to perform in a row without damaging the ciphertext.
