The present disclosure relates to the field Quantum Key distribution (QKD) and discloses an apparatus () and method () for adjusting the phase modulator's modulating signal time reference in a phase-based QKD system. The QKD system comprises a pulse generator () that generates optical pulses and a phase modulator () that modulates the phase of each of the pulses. The apparatus () comprises abeam splitter/tap (), a 1-bit delay interferometer (), two photodetectors (), and a processing device (). The splitter feeds the phase modulated optical pulses to the interferometer (). Two photo detectors are connected to the constructive and destructive output legs () of the interferometer (). The photo detectors' output are then converted to digital signals and fed to the processing device (). The processing device () measures the average power at both the legs of the interferometer () to detect delay between optical signal and modulating signal and adjusts the delay to accurately align the phase modulator () with the pulse generator ().

A security patch tool includes a retrieval engine, a parser, and a reporting engine. The retrieval engine retrieves, from a first database, a log indicating a plurality of patches that have been applied and whether each patch of the plurality of patches was applied successfully. The parser determines, based on the log, a second plurality of patches of the plurality of patches that were not applied successfully and determines, based on the log, an error code for each patch of the second plurality of patches. The retrieval engine further retrieves, from a second database, a remedy for each error code for each patch of the second plurality of patches. The reporting engine generates a report indicating the plurality of patches, the error code for each patch of the second plurality of patches, and the remedy for each error code for each path of the second plurality of patches.

Embodiments of the invention are directed to a system, method, or computer program product for configuring multiple computing devices over a network using a single software application. Each of the multiple computing devices may be accessible over a network. The invention links each of the multiple computing devices to the single software application. The invention determines commands which are executable by each of the multiple computing devices to configure each of the multiple computing devices. The invention further communicates the commands based on receiving user input in the single software application. The invention then determines whether each of the multiple computing devices were correctly configured. The invention may further track the configuration process of the devices using tests and procedures. The invention tracks information related to the configuration of the devices and displays such information in report form as a result of receiving a report request in the single software application.
