Post-quantum cryptography: protecting data for the future
IBM produced a quantum computer with 127 qubits in 2021, one with 433 qubits is due to follow this year and one with over 1000 qubits is planned for 2023. If development continues at this rate, Shor's algorithm could easily break classic asymmetric encryption methods such as RSA or ECDSA, which are predominantly used on the internet today, in the near future.
To meet this challenge, a number of post-quantum algorithms are currently being developed, which are already being used in products from companies such as CloudFlare and Amazon.
This talk will show the current state of post-quantum algorithms. The functionalities of the shor- and post-quantum algorithms presented will be briefly outlined. The focus is on the evaluation of currently available methods of post-quantum cryptography:
- How secure are the current algorithms compared to non-quantum secure algorithms against classical attacks?
- What security tests have the algorithms undergone?
- How many resources (CPU time, memory) are used compared to previous classical algorithms?
- How costly is it to use these new algorithms?
- How many devices/systems support post-quantum algorithms?
The lecture will be complemented by a hands-on presentation showing the post-quantum algorithms Kyber and Dilithium in action.
