Publication number: 20180359086Abstract: According to an embodiment, a quantum communication device includes a corrector and a retransmission controller. The corrector is configured to generate corrected key data by performing error correction on received key data received from a transmitting device through a quantum channel. The retransmission controller is configured to transmit a retransmission request including retransmission target address information to the transmitting device through a control channel when a retransmission request condition is satisfied, and receive retransmission key data corresponding to the retransmission target address information from the transmitting device through the control channel. After receiving the retransmission key data, the corrector replaces corrected key data corresponding to the retransmission target address information with the retransmission key data.Type: ApplicationFiled: February 16, 2018Publication date: December 13, 2018Applicant: Kabushiki Kaisha ToshibaInventors: Alex Dixon, Kazuaki Doi

Patent number: 10103818Abstract: A transmitting device according to an embodiment include a transmission unit, a storage unit, a cache unit, a reception unit, and a sifting processing unit. The transmission unit transmits a transmission photon to a receiving device. The storage unit stores transmission photon information including transmission timing at which the transmission photon is transmitted, a transmission bit indicated by the transmission photon, and a transmission base of the transmission photon. The cache unit stores, one or more pieces of transmission information including the transmission timing after an elapse of a no-use period of the transmission photon. The reception unit receives, from the receiving device, the reception timing and a reception base of the reception photon. The sifting processing unit performs sifting processing on the transmission bit by making a correlation between the transmission base and the reception base on the basis of the reception timing and the transmission timing.Type: GrantFiled: February 22, 2017Date of Patent: October 16, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Akira Murakami, Yoshimichi Tanizawa, Alex Dixon

Patent number: 9893884Abstract: According to an embodiment, a communication device is connected to another communication device through an optical communication path to generate an identical cryptographic key shared among the communication devices. The communication device includes a key sharing unit, a key distilling unit, a measuring unit, and a varying unit. The key sharing unit is configured to generate a shared bit string through quantum key distribution with the another communication device. The key distilling unit is configured to generate the cryptographic key from the shared bit string by a key distillation process. The measuring unit is configured to measure an error rate occurring in a photon string transmitted and received via a photon communication channel. The varying unit is configured to vary, based on the error rate, a communication function by applying a limitation on the optical data communication of an optical data communication channel or by releasing the limitation.Type: GrantFiled: March 11, 2015Date of Patent: February 13, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Yoshimichi Tanizawa, Alex Dixon

Patent number: 9455827Abstract: According to an embodiment, a communication apparatus includes a cryptographic key storage, a transmitter, a receiver, and a sharing controller. The cryptographic key storage stores therein one or more cryptographic keys shared with an external device. The transmitter transmits specifying information that specifies at least one of the cryptographic keys to the external device. The receiver receives determination information that indicates a result of determination, which is made by the external device based on the specifying information, on whether the shared cryptographic key is consistent between the apparatus and the external device. When receiving the determination information indicating that the shared cryptographic key is inconsistent between the apparatus and the external device, the sharing controller deletes the cryptographic key specified by the specifying information from the cryptographic key storage.Type: GrantFiled: July 31, 2014Date of Patent: September 27, 2016Assignee: Kabushiki Kaisha ToshibaInventors: Yoshimichi Tanizawa, Hideaki Sato, Ririka Takahashi, Alex Dixon
