  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.

    Abstract : PAPR Credentials is the name of a not yet published credential scheme that provides conditional privacy for its users. This means that an administrator can choose to revoke a user's anonymity. READ MORE

  4. 3. Secret Sharing with Threshold Schemes

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Håkan Johansson; [2020]
    Keywords : Secret; sharing; threshold; schemes; cheating; shadow; dealer; Shamir; Blakley; Mignotte; Asmuth-Bloom;

    Abstract : In this thesis, four different methods for secret sharing with threshold schemes will be investigated. We will discuss theory, implementation and security aspects. For example, we show how some known attacks are implemented.The methods considered in this thesis, are the schemes by Shamir, Blakley, Mignotte and Asmuth-Bloom. READ MORE

  5. 4. Discreet Discrete Mathematics : Secret Communication Using Latin Squares and Quasigroups

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Christoffer Olsson; [2017]
    Keywords : Cryptology; Cryptography; Latin squares; Row-latin squares; Quasigroups; Secret sharing schemes; Kryptologi; Kryptografi; Latinska kvadrater; Rad-latinska kvadrater; Kvasigrupper; Hemlighetsdelning;

    Abstract : This thesis describes methods of secret communication based on latin squares and their close relative, quasigroups. Different types of cryptosystems are described, including ciphers, public-key cryptosystems, and cryptographic hash functions. There is also a chapter devoted to different secret sharing schemes based on latin squares. READ MORE
