Due to developments within the field of quantum computers, the need for developing and implementing quantum-resistant cryptographic (post-quantum cryptography) algorithms has become more urgent. The security of current public-key cryptosystems relies on the hardness of factoring large integers or solving discrete logarithm problems. However, these mathematical problems can be solved in polynomial time (efficiently) using a quantum computer. In response, there has been intense research into post-quantum cryptography. This science is the study of cryptosystems that would be secure against adversaries who have both quantum and classical computers and that can be deployed without drastic changes to existing communication networks and protocols. This paper gives an overview of the current state of the art of the alternative public-key schemes that have the capability to resist quantum computer attacks and consider their main characteristics.

Keywords : Quantum computing; Post-quantum cryptography.
