NEC: Successful quantum cryptography communication: Transmission and backup of electronic medical records
-NEC and NICT experiment-
NEC,
NICT,
ZenmuTech,
Recently, we have sent and received sample data of electronic medical records by quantum cryptography.
Announced that “successful experiment with distributed backup while maintaining confidentiality”.
Quantum cryptography experiment:
In the experiment
NICT uses the quantum cryptography network “Tokyo QKD Network” that has been in operation since 2010.
NEC has built a system that allows data storage and cross-reference.
By “quantum key distribution” that uses photons for communication, information can be shared without eavesdropping in principle.
“Quantum key distribution”:
Provided by a medical institution in Tokyo,
Approximately 10,000 sample data of electronic medical records are sent.
Divide the data and store the fragments on the server in a distributed manner.
Demonstrate data management and restoration using secret sharing technology to prevent information theft.
results of the experiment:
Build a secure network and backup system.
“Cross-reference of data at multiple medical institutions” can be confirmed in real time.

Succeeded in a demonstration experiment in which electronic medical records are concealed using quantum cryptography and transmission / secret sharing backup is performed.

NEC,
NICT,
ZenmuTech,
Outline of the demonstration experiment:
This time, we will transmit sample data of about 10,000 electronic medical records.
Confidential with quantum cryptography
Secure data transmission over the network
Backup using secret sharing
We have developed a system to do.
Secret sharing technology / demonstration method:
In theory, to a third party (eavesdropper) with any computing power. Without leaking information
Share the encryption key between two remote points.
Quantum key distribution: (Note 8)
While concealing the transmission of sample data of electronic medical records with quantum cryptography,
We also verified the distributed management and restoration of data using secret sharing technology.
Confidential communication method and configuration:
In this demonstration experiment, a system environment was constructed assuming a medical institution in Tokyo.
NEC’s line encryption device (Note 10) is used for secret communication to a secret distributed network.
The encryption key that is actually supplied from the quantum key distribution device of Tokyo QKD Network,
Combined with modern encryption AES (Advanced Encryption Standard).
This makes it difficult to decipher even with a quantum computer, and realizes highly secure and confidential communication.
