WebThe SVP and CVP problems, and others, give rise to a whole new area called Post-Quantum Cryptography (PQC). Example: Putting the above ideas together, one may encounter statements such as: The public key encryption scheme XYZ is IND-CCA secure assuming the RSA-problem is hard and AES is a PRP. WebAuthentication and digital signatures are a very important application of public-key cryptography. For example, if you receive a message from me that I have encrypted with my private key and you are able to decrypt it using my public key, you should feel reasonably certain that the message did in fact come from me. WebThe many examples of cryptography are DES, AES, RSA, and Diffie-Hellman key exchange. Cryptography has some challenges, including weak keys, insider threats, and incorrect use of keys.
