The cryptographic protocols mainly comprise functionalities such as public-key encryption, digital signatures, and key exchange. These cryptographic protocols are based on the difficulty of certain mathematical operations, such as finding the prime factors of a very large integer. However, recent advances in quantum computing mean that these difficult math problems might soon be solved efficiently, with a potentially serious impact upon our security. Realizing the availability of quantum computers from research labs to general purpose use in the near future, the preparation against such a threat has taken shape recently, and happening to be a fast growing topic of research referred as post-quantum cryptography (PQC). Nowadays, certain candidate families of post-quantum schemes have been realized including code-based, hash-based, multivariate, lattice-based and supersingular isogeny-based. Security of all these primitives are based on different mathematical problems which are believed to be hard even with respect to quantum computation and quantum communications. In this project, we aim to achieve the following goals: • To study the existing PQC schemes and demonstrate state of the art PQC following an extensive review. • To propose post-quantum schemes taking in account their possible application to IoT security or Blockchain.
