TC: Small: Collaborative Research: Exploring a Robust Quantum Cryptography Protocol for Securing Optical Burst Switching Networks

该方案探索了一种用于保护光突发交换(OBS)网络的健壮的量子密码协议，提供了一种从根本上使基于OBS的未来互联网值得信赖的方法。由于OBS网络在报头与其关联的突发之间具有一对一的对应关系，因此可以利用相同的关系进行加密。基于量子的方法使安全地分发密钥成为可能，以便使用唯一的密钥对每个突发进行加密和解密。由于著名的BB84量子密码协议对实际光源发射的多个光子容易受到虹吸攻击，我们使用了一种新的三阶段量子密码协议，该协议基于偏振向量的随机旋转，对虹吸攻击具有免疫力。新的三阶段量子密码协议允许在量子密钥交换中使用实际的光子源，从而使量子密码服务扩展到可信路由器之外是可行的。研究了三阶段全量子协议在不同噪声环境下不同密钥生成率下的性能。该协议的实现采用了量子位相调制，而不是偏振调制，这在光纤的长距离传输中是不稳定的。该方案中进行的研究包括设计一个集成的安全路由器和研究特定服务的量子密码协议。本研究将在可重构光突发交换实验台上进行验证。

This proposal explores a robust quantum cryptography protocol for securing optical burst switching (OBS) networks, providing a means to make the OBS-based future Internet trustworthy from the ground up. Since the OBS network has a one-to-one correspondence between the header and its associated burst, the same relationship can be exploited for encryption. The quantum-based methodology makes it possible to distribute keys securely so that each burst is encrypted and decrypted with a unique key. As the well-known BB84 quantum cryptography protocol is susceptible to siphoning attacks on the multiple photons emitted by practical sources, we use a new 3-stage quantum cryptography protocol which is immune to such siphoning attacks, for it is based on random rotations of the polarization vector. The new 3-stage quantum cryptography protocol allows practical photon sources to be used in the quantum key exchange, making it feasible to extend quantum cryptography services beyond trusted routers. The 3-stage all quantum protocol is being investigated for its performance in different noise situations for different key generation rates. The implementation of the protocol uses quantum phase modulation rather than polarization modulation which is not stable in the long transmission over fiber. The research conducted in this proposal includes the design of an integrated secure router and investigation of quantum cryptography protocols for specific services. This research will be verified on a reconfigurable optical burst switching test bed.
