7 month 6 Daily news , Tuesday local time , National institute of standards and technology （NIST） After the third round of screening of the post quantum cryptography standardization project, four encryption algorithms were announced , The purpose is to ensure the security of computer data when the quantum computer is mature enough to crack the current encryption technology .
Scientists have confirmed that , If quantum computer technology continues to develop , One day, we can crack the current encryption technology .NIST The purpose of designing and testing post quantum cryptography is to continue to protect computer data after the quantum computer matures . stay NIST Selected 4 Of these technologies , Yes 2 It is expected to be more widely used . One is called Crystals-Kyber Algorithm , It is used to establish the digital key required for two computers to share encrypted data . The other is Crystals-Dilithium Algorithm , Used to digitally sign encrypted data , Determine who is sending data . These algorithms may take two years to standardize , Then integrated into today's computer software and hardware .
Quantum computers have been developing steadily , But it may take years to develop a powerful machine capable of cracking current encryption technology . in any case , Strengthen data protection 、 Consolidating encryption technology is an urgent problem , Whether it's looking for a new encryption algorithm 、 It will take several years to ensure the safety of the technology and promote its use .
Quantum computer software and hardware developers Quantinuum Duncan, director of network security ・ Jones (Duncan Jones) say ,“ For the time range of launching attacks using quantum computers , It is generally believed that 10 To 15 year .”“ But considering that ’ Now invade , Decrypt later ’ The possibility of , We think the attack may have begun .”
It should be noted that , Cryptocurrency also uses current encryption technology , This means that quantum computers may also fundamentally destroy cryptocurrencies .
