Quantum-resistant End-to-End Secure Messaging and Email Communication

Abstract

With recent advances on the capabilities of quantum computers and the seminal work by Shor on the prime factorization of integers with quantum algorithms, the threat of quantum computers is looming over public-key based cryptographic systems. Two distinct areas of research – post-quantum and quantum cryptography – provide the technical means to secure cryptographic systems against potentially powerful enough quantum computers. As both technologies are now becoming readily available, integration in a wide range of applications to understand their characteristics and trade-offs and the associated evaluation is of importance.
