Post-Quantum Cryptography


On Thursday, August 26, 2021, the College of Science and Technology at the University of Human Development held and international virtual workshop in cooperation with the Informatics Department (Selmer Center in Secure Communication) at the University Bergan in Norway via zoom under the title of Post-Quantum Cryptography.

The idea of making use of properties of quantum particles for computation was
suggested in the 1980's, but the interest was mostly theoretical. It stayed in shadow
until 1994, when Shor proposed a quantum algorithm that was able to factor integers in polynomial time instead of exponential
time. This algorithm causes the quantum computers to pose a series threat to many
of the classical and currently used cryptographical solutions. For a future full of the quantum computers, a new foundation for asymmetric key cryptography are required.
Cryptography communities are designing new algorithms to be set up for the time that quantum computers being existed. Post-quantum cryptography refers to cryptographic algorithms that thought to be secure against quantum computers.
