The 2024 International Conference on Advances in Computing Research (ACR'24)
Del 3 al 5 de junio de 2024, Madrid, España.
The situation of the current cryptography (pre-quantum), some aspects related to quantum cryptography, and the present state of the new proposals for the post-quantum cryptography will be visited. The talk will then emphasize that the pre-quantum cryptography has its days numbered due to the publication of several quantum algorithms capable of breaking, in an efficient way, the math problems on which the security of this cryptography is based. Then, the basis of the quantum key distribution (QKD) algorithms will be commented. The current status of the call made by NIST in the search for new cryptographic standards which must be resistant to quantum computing and known as post-quantum cryptography (PQC) will be described. The mathematical problems on which the new standards for digital signature and key encapsulation mechanisms (KEM) are based will be briefly presented.
