The Need For Quantum - Resistant Cyber Security : A Review
K Subhashree, S, Kavitha, K, Sanjay · Zenodo (CERN European Organization for Nuclear Research) · 2019
Conventional cyber security, especially public key cryptosystems depend upon the difficulty of solving large integer factorization and discrete log problems. The most straightforward way to solve these problems is to try all possible keys, which would be far too difficult for conventional computers. But the speed in which quantum computing is growing has posed a great threat to the conventional cryptosystems. This paper reviews how conventional public key cryptosystems might crumble under quantum computing and the need for quantum – safe cryptography.
