The cryptographic algorithms in use today are secure against all known attacks using modern technology. However, this will not always be true. With the development of large quantum computers, which will be available in the near future, classical asymmetric or public-key cryptography security will be broken. The impending threat to the security of classical cryptography has prompted the development of algorithms that are believed to be secure against both classical and quantum computers. These post-quantum cryptographic algorithms are an area of active development and will be rolled out to replace their quantum-vulnerable counterparts within the next few years.

This white paper gives a detailed introduction to the world of post quantum cryptography–a great start to the exciting journey ahead of us.
