The greatest threat is to public cryptography or asymmetric algorithms used for ____.

Question

The greatest threat is to public cryptography or asymmetric algorithms used for ____.

A. Digital signatures and

B. Key exchange

C. Both A and B

D. None of the mentioned above

It is public cryptography, or asymmetric algorithms, that are under the greatest threat, as they are utilized for digital signatures and key exchange. For example, one of the most well-known quantum algorithms is the Shor algorithm, which may be used to break the RSA and Elliptic Curve methods once a universal quantum computer is available.
