Post-quantum cryptography (PQC)

“

- [Lecturer] Post-Quantum Cryptography, or PQC, refers to cryptographic algorithms designed to be secure against attacks by quantum computers. Some of the key points. Quantum computers have the potential to break many of the cryptographic systems currently in use, such as RSA and ECC. RSA being Rivest-Shamir-Adleman, ECC being elliptic curve cryptography. These rely on the difficulty of factoring large integers or computing discreet logarithms. Quantum resistance. PQC algorithms are designed to resist cryptanalytic attacks by quantum computers. Harvest Now, Decrypt Later, or HNDL. This particular threat involves collecting encrypted data now and then decrypting it later when quantum computers become powerful enough or more powerful. Most current symmetric cryptographic algorithms and hash functions are considered relatively secure against quantum attacks, usually because the keys are rotated on a regular basis. There are some NIST standards to be aware of on the SecurityX exam. The…
