Secure Data Access in Cloud Environments Using Quantum Cryptography
- 基于BB84协议实现量子密钥分发，密钥可检测窃听
- 采用量子一次性密码加密数据，理论上无法破解
- 适合对安全性要求极高的云服务场景
云计算虽便利数据存储与访问，但安全挑战日益严峻。传统加密方法在量子计算机时代将不再可靠。本文提出利用量子密码学保障云端数据安全：采用BB84协议进行量子密钥分发（QKD），通过光子传输生成不可窃听的密钥；使用量子一次性密码（QOTP）对数据进行加密与解密，确保信息完全私密。实验验证该方案可在存在量子计算威胁的环境下仍保持数据安全。该组合方法为未来云环境提供了强抗攻击的防护机制，使数据在存储与共享中获得持久安全保障。
原文摘要 · Abstract (English)
Cloud computing has made storing and accessing data easier but keeping it secure is a big challenge nowadays. Traditional methods of ensuring data may not be strong enough in the future when powerful quantum computers become available. To solve this problem, this study uses quantum cryptography to protect data in the cloud environment. Quantum Key Distribution (QKD) creates secure keys by sending information using quantum particles like photons. Specifically, we use the BB84 protocol, a simple and reliable way to make secure keys that cannot be stolen without detection. To protect the data, we use the Quantum One Time pad (QOTP) for encryption and decryption, ensuring the data stays completely private. This study shows how these Quantum methods can be applied in cloud systems to provide a strong defense against hackers, even if they have access to quantum computers. The combination of QKD, BB84, and QOTP creates a safe and reliable way to keep data secure when it is stored or shared in the cloud. Using quantum cryptography, this paper provides a way to ensure data security now and in the future, making cloud computing safer for everyone to store their data securely and safely.
