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.

本提案探索了一种用于保护光突发交换（OBS）网络的鲁棒量子加密协议，提供了一种使基于OBS的未来互联网从头开始值得信赖的方法。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。基于量子的方法使得安全地分发密钥成为可能，这样每个突发都可以用唯一的密钥进行加密和解密。针对众所周知的BB84量子密码协议对实际光源发射的多光子容易受到虹吸攻击的问题，我们采用了一种新的3阶段量子密码协议，该协议基于偏振矢量的随机旋转，不受这种虹吸攻击的影响。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，使量子密码服务扩展到可信路由器之外成为可能。研究了三阶段全量子协议在不同密钥生成速率下在不同噪声情况下的性能。该协议的实现采用量子相位调制而不是偏振调制，偏振调制在光纤长时间传输中不稳定。本提案的研究内容包括集成安全路由器的设计和针对特定业务的量子加密协议的研究。该研究将在可重构光突发交换试验台上进行验证。
