Part 2/9:
The National Security Agency (NSA) has acknowledged this looming threat, indicating that a sufficiently powerful quantum computer could undermine all widely deployed public key algorithms. Given that quantum computers capable of achieving such feats are anticipated within the next five to ten years, the urgency to shift cryptographic strategies has intensified. Recently, the U.S. Congress passed legislation mandating that all agencies transition to new forms of cryptography that are resistant to quantum attacks. While existing encryption methods, such as RSA, have served securely for over 40 years, the time for adaptation is rapidly approaching.
