摘要： Systems and methods for enhanced quantum key distribution (QKD) using an actively compensated QKD system (10). The method includes exchanging quantum signals (QS) between first and second QKD stations (Alice and Bob) and measuring the quantum signal error (QBER). An error signal (S E ) representative of the system visibility error is then generated. An error-signal threshold (S TH ) that defines a system visibility error limit is then selected. Those qubits measured with the condition S E > S TH are called "above-threshold" qubits, while those qubits measured with the condition SE ≤ S TH are called "below-threshold" qubits. Only below-threshold qubits are stored and used to form the final quantum key. This is accomplished by sending a blanking signal (S B ) to the memory unit (130) where the qubits are stored. The blanking signal prevents above-threshold qubits from being stored therein. The raw quantum key so formed has few errors and thus forms a longer final quantum key for a given number of exchanged quantum signals.
摘要翻译：使用主动补偿QKD系统的增强量子密钥分配（QKD）的系统和方法（10）。该方法包括在第一和第二QKD站（Alice和Bob）之间交换量子信号（QS）并测量量子信号误差（QBER）。然后产生代表系统可见性错误的误差信号（SE）。然后选择定义系统可见性错误限制的错误信号阈值（STH）。以条件SE> STH测量的量子位称为“高于阈值”量子位，而用条件SE = STH测量的量子位称为“低于阈值”量子位。只有低于阈值的量子位被存储并用于形成最终量子密钥。这通过向存储量子位的存储单元（130）发送消隐信号（SB）来实现。消隐信号防止高于阈值量子位的存储在其中。如此形成的原始量子密钥具有很少的误差，因此对于给定数量的交换量子信号形成更长的最终量子密钥。

摘要： A fast bit-error rate (F-BER) calculation mode for a QKD system (10) is disclosed, wherein the method includes establishing versions of a sifted key in respective sifted-bits (SB) buffers in respective QKD stations (Alice and Bob). The method also includes sending Alice's version of the sifted key to Bob, and Bob performing a comparison of the two sifted key versions. The number of bit errors between the two sifted key versions relative to the length of the sifted key yields the F-BER. The F-BER is calculated much more quickly than the conventional ("normal") BER calculation ("N-BER"), which involves performing a relatively complex error-correction algorithm. The F-BER calculation mode is particularly useful in quickly setting up and/or calibrating a QKD system, and can be repeated quickly to provide updated BER measurements after each QKD system adjustment.
摘要翻译：公开了一种用于QKD系统（10）的快速误码率（F-BER）计算模式，其中该方法包括在相应的QKD站（Alice和Bob）中的相应的筛选位（SB）缓冲器中建立筛选密钥的版本）。该方法还包括将筛选密钥的Alice版本发送给Bob，Bob执行两个筛选密钥版本的比较。两个筛选密钥版本之间的相对于筛选密钥长度的位错误的数量产生了F-BER。比传统（“正常”）BER计算（“N-BER”）更快地计算出F-BER，其涉及执行相对复杂的纠错算法。 F-BER计算模式在快速设置和/或校准QKD系统中特别有用，并且可以在每个QKD系统调整后快速重复以提供更新的BER测量。

摘要： Key management and user authentication systems and methods for quantum cryptography networks that allow for users securely communicate over a traditional communication link (TC-link). The method includes securely linking a centralized quantum key certificate authority (QKCA) to each network user via respective secure quantum links or "Q-links" that encrypt and decrypt data based on quantum keys ("Q-keys"). When two users (Alice and Bob) wish to communicate, the QKCA sends a set of true random bits (R) to each user over the respective Q-links. They then use R as a key to encode and decode data they send to each other over the TC-link.

摘要： Systems and methods for exchanging and processing encoded quantum signals in quantum key distribution (QKD) systems in real time are disclosed. A stream of quantum signals (QS) is sent from Alice to Bob. Alice only encodes sets or "frames" (F) of the streamed quantum signals based on receiving a "ready" message from Bob. This allows for Bob to finish processing the previous frame of data by allowing different bit buffers (44A,B; 50A,B; 60A,B; 61A,B; 64A,B) to fill and then be used for data processing. This approach results in gaps (G) in between frames wherein quantum signals in the stream are sent unencoded and ignored by Bob. However, those quantum signals that are encoded for the given frame are efficiently processed, which on the whole is better than missing encoded quantum signals because Bob is not ready to receive and process them.
摘要翻译：公开了用于实时交换和处理量子密钥分发（QKD）系统中的编码的量子信号的系统和方法。量子信号流（QS）从Alice发送给Bob。 Alice只编码组或“帧” （F）基于接收到“准备好”的量化信号来自Bob的消息。这允许Bob通过允许不同的位缓冲器（44A，B; 50A，B; 60A，B; 61A，B; 64A，B）填充然后用于数据处理来完成前一帧数据的处理。该方法导致帧之间的间隙（G），其中流中的量子信号未被编码且被Bob忽略。然而，对于给定帧编码的那些量子信号被有效地处理，总体上比丢失编码的量子信号要好，因为鲍勃没有准备好接收和处理它们。

摘要： QKD system networks (50, 200, 300) and method s of communicating between end-users (P1, P2) over same are disclosed. An example QKD system network (50) includes a first QKD station (A1) and a second QKD station (A2) with a relay station (58) in between. The relay station includes a single third QKD station (B) and an optical switch (55). The optical switch allows the third QKD station to alternately communicate with the first and second QKD stations so as to establish a common key between the first and second QKD stations. The end-users are coupled to respective QKD stations A1 and A2. A secret key (S) is shared between P1 and P2 by QKD station B being able to independently form keys with A1 and A2. This basic system, represented as P1-A1-B-A2-P2, can be expanded into more complex linear networks, such as P1-A1-B1-A2-B2-P2 with B1 and A2 making up the relays. The basic QKD system network can also be expanded into multi-dimensions.

摘要： A method of integrating quantum key distribution (QKD) with Internet protocol security (IPSec) to improve the security of IPSec. Standard IPSec protocols impose limits on the frequency at which keys can be changed. This makes efforts to improve the security of IPSec by employing quantum keys problematic. The method includes employing multiple security associations (SA) in a manner that enables a high key flipping rate and that enables combining of quantum keys with classical keys generated by Internet Key Exchange (IKE), thereby enabling QKD-based IPSec.

摘要： A QKD cascaded network (5) with loop-back capability is disclosed. The QKD system network includes a plurality of cascaded QKD relays (10, 20, 30) each having two QKD stations Alice (A) and Bob (B) therein. Each QKD relay also includes an optical switch (50). The optical switch is optically coupled to each QKD station in the relay, as well as to the input ports (PI) of the relay. In a first position, the optical switch allows for communication between adjacent relays. In a second position, the optical switch allows for pass-through communication between the QKD relays (10 and 30) that are adjacent the relay whose switch is in the first position. Also in the second position, the optical switch allows for communication between the QKD stations A and B within the relay. This, in turn, allows for diagnostic measurements to be made of one or both of the QKD stations via an optical path (90) that is entirely within the relay station enclosure (12, 22, 32).

摘要： A method for enhancing the security of a quantum key distribution (QKD) system having QKD stations Alice and Bob (10) is disclosed. The method includes encrypting key bits generated by a random number generator and sent to a polarization or phase modulator to encode weak optical pulses as qubits to be shared between Alice and Bob (10). Key bit encryption is achieved by using shared password and a stream cipher. Bob obtains at least a subset of the original key bits used by Alice (10) by utilizing the same cipher stream and the shared password.

摘要： A method of encrypting information using an encryption pad based on keys exchanged between quantum key distribution (QKD) stations is disclosed. The method includes establishing raw keys between two stations using QKD, processing the keys to establish a plurality of matching privacy amplified keys (Fig 8, 14-1) at each station and buffering (14-2) the keys in a shared key schedule. The method also includes the option of expanding (14-4, 14-3) one or more of the keys in the shared key schedule using a stream cipher to create a supply of expanded keys (14-3) that serve as pads for one-time-pad encryption.
