What is post-quantum cryptography (PQC)?

Post-quantum cryptography is a class of cryptographic algorithms resistant to attacks by quantum computers. These algorithms are designed to protect data in scenarios where quantum computing becomes powerful enough to break traditional encryption methods.

Why is the US accelerating the transition to PQC?

The transition is driven by the growing threat from quantum computers, which could compromise existing cryptographic standards like RSA and ECC. This poses significant risks to the security of government and corporate data.

Which companies are involved in the development of quantum technologies in the US?

Major technology companies, including IBM and Google, are actively participating in this initiative. They are developing quantum processors and algorithms, which will expedite the adoption of new security standards.

Quick answer

The US has mandated federal agencies to transition to post-quantum cryptography (PQC) by 2030 to safeguard against quantum computing threats.

The US administration has signed an executive order requiring all federal agencies to complete their transition to post-quantum cryptography (PQC) by the end of 2030. This move responds to growing concerns about the advancement of quantum computers, which can break traditional encryption methods such as RSA and ECC.

A second executive order was simultaneously signed to accelerate the development and adoption of quantum technologies in the country. The signing ceremony was attended by leaders from major technology companies, including IBM and Google, highlighting the importance of collaboration between the government and the private sector in this area.

Experts note that the transition to PQC is not only a security imperative but also a strategic step to maintain US technological leadership. Although still in the early stages of development, quantum computers have already demonstrated potential for revolutionary changes in cryptography, finance, and scientific research.

Federal agencies must now develop migration plans for the new standards, including vulnerability assessments and testing of PQC solutions. This will require significant investments in infrastructure and personnel training.
