量子計算如何威脅網路安全
How Quantum Computing Could Threaten Online Security
量子運算代表了現代科技最重大的轉變之一。
Quantum computing represents one of the most significant shifts in modern technology.
目前，網際網路依賴公開金鑰密碼學來保護銀行和私人訊息等敏感資訊。
Currently, the internet relies on public-key cryptography to protect sensitive information like banking and private messages.
然而，強大的量子電腦可能會運用稱為秀爾演算法(Shor’s Algorithm)的東西來輕鬆破解這些防禦措施。
However, a powerful quantum computer could use something called Shor’s Algorithm to break these defenses effortlessly.
這個恐怖的里程碑通常被稱為量子末日(Q-Day)。
This terrifying milestone is often referred to as Q-Day.
危險已透過一種稱為「先截獲，後解密」(Harvest Now, Decrypt Later)的做法而至。
The danger is already here through a practice called Harvest Now, Decrypt Later (HNDL).
為了對抗這點，全世界正轉向後量子密碼學(Post-Quantum Cryptography)，該技術使用了新的、具有耐量子性的數學基礎。
To combat this, the world is shifting toward Post-Quantum Cryptography (PQC), which uses new, quantum-resistant mathematical foundations.
組織也正專注於密碼敏捷度(crypto-agility)，確保系統能夠迅速更新以處理未來的威脅。
Organizations are also focusing on crypto-agility, ensuring systems can be updated quickly to handle future threats.
