The thought of Quantum computing advances and Quantum computers being freely available will make our current cryptographic systems redundant. PKI will expire soon. Are there new algorithms being developed and also what is the approach. Is the NSA doing something about this? Is it something on your Organisation's radar today ?
Hi, fresh here so apologies for any mistakes by me! A question about RSA, strenghth and quantum computing (qubits), I have heard in conferences and lectures over the past years quite different stories on how many qubits it takes to actually break RSA cryptography, a range from "a few" to "several hundreds", I guess this also depends on the quality of the qubits and their entanglement, but does anyone have a good estimate?
Nist is at final stage to define PQC Algorithm
The only big problem is .. htat those will be good untill someone else will find Qauntum Algorithms to break them.
The best way is start to consider the Crypto Agility as a must.
The main issue is having sufficient Quantum Memory which is stable enough to accommodate the Quantum Cryptography algorithms in order to break the RSA keys, there have been some exaggerations from various sources, which under scrutiny fail.
We may reach that level in 2026 or up to 2031 - the race is on at the present time.
Although the State Actors are actively working underground to achieve this pouring vast sums into the research and technologies required.
