Post-quantum cryptography research is mostly focused on six different approaches:
Lattice-based cryptography
This approach includes cryptographic systems such as See more

In cryptography research, it is desirable to prove the equivalence of a cryptographic algorithm and a known hard mathematical problem. These proofs are often called "security reductions", … See more

A public-key system demonstrates a property referred to as perfect forward secrecy when it generates random public keys per session for … See more

One of the main challenges in post-quantum cryptography is considered to be the implementation of potentially quantum safe algorithms into existing systems. There are tests done, for example by Microsoft Research implementing PICNIC in a See more

One common characteristic of many post-quantum cryptography algorithms is that they require larger key sizes than commonly used "pre-quantum" public key algorithms. There … See more

The Open Quantum Safe (OQS) project was started in late 2016 and has the goal of developing and prototyping quantum-resistant … See more
