摘要：
In 2008, Satoshi Nakamoto proposed an innovative idea to construct a cryptocurrency so called- Bitcoin by using cryptographic hash functions, elliptic curve digital signatures, and consensus algorithm over P2P distributed network. After its birth, thousands of cryptocurrencies such as Ethereum and Ripple, etc are widely announced around the world.
However, The exponential advancement of quantum computers jeopardizes the practical security of most cryptocurrencies whose security is based on the attack against the classical adversary.
In this talk, we raise the security issues of most cryptocurrencies if the quantum computers become available in the near future to break the current cryptographic primitives using Shor and Glover algorithms and introduce the NIST activities for Post Quantum Cryptography standard by soliciting the candidate cryptographic primitives for signatures, encryption and key-establishment over the world.
