Abstract: 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.

Abstract: Systems and methods for exchanging and processing encoded quantum signals in quantum key distribution (QKD) systems in real time. A stream of quantum signals is sent from Alice to Bob. Alice only encodes sets or “frames” 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 to fill and then be used for data processing. This approach results in gaps 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.

Abstract translation: 在量子密钥分配（QKD）系统中实时交换和处理编码量子信号的系统和方法。 量子信号流从爱丽丝发送到鲍勃。 基于从Bob接收到“准备”消息，爱丽丝只对流量子信号的集合或“帧”进行编码。 这允许Bob通过允许不同的位缓冲器填充然后用于数据处理来完成对前一帧数据的处理。 这种方法导致帧之间的间隙，其中流中的量子信号被未被编码并由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，由于Bob没有准备好接收和处理这些量子信号，所以总体上比编码的量子信号更好。

Abstract: 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 at each station and buffering the keys in a shared key schedule. The method also includes the option of expanding one or more of the keys in the shared key schedule using a stream cipher to create a supply of expanded keys that serve as pads for one-time-pad encryption.

Abstract: A medical voice data system includes a hand-held recording device, an electronic information carrier (EIC), and a host station. The hand-held device records medical information from a user that is examining a person in an extreme environment such as battlefield or disaster area. EICs are stored within a housing interior and can be dispensed therefrom by the user. Recording electronics within the housing interior are operably connected to at least one of the EICs. A microphone is operably connected to the recording electronics to record on a EIC medical information about the injured person. The EIC is configured to be attached to and travel with the person as they are evacuated so that the recorded medical information is immediately available to medical personnel at a care center via the host station.

Abstract: 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 increasing the size of the Security Association (SA) Table in a manner that enables a high key change rate so that the quantum keys can be combined with the classical keys generated by Internet Key Exchange (IKE). The invention includes a method of creating the SA Table by combining quantum keys generated by the QKD process with classical keys generated by the IKE process, thereby enabling QKD-based IPSec.

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

Abstract: 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).

Abstract: Systems and methods for enhanced quantum key distribution (QKD) using an actively compensated QKD system. The method includes exchanging quantum signals between first and second QKD stations and measuring the quantum signal error. An error signal SE representative of the system visibility error is then generated. An error-signal threshold STH that defines a system visibility error limit is then selected. Those qubits measured with the condition SE>STH are called “above-threshold” qubits, while those qubits measured with the condition SE≦STH 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 SB to the memory unit 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.
