World-first Demonstration of Real-time Transmission of Whole-genome Sequence Data Using Quantum Cryptography
(WorldNews Japan)

Toshiba Corporation (TOKYO: 6502) and the Tohoku University Tohoku Medical Megabank Organization (ToMMo) have succeeded in the world`s first quantum cryptography transmission of whole-genome sequence data with data volumes exceeding several hundred gigabytes. Since speeds for key distribution in quantum cryptographic communication technologies are currently about 10 Mbps(Note 1) at maximum, the speed at which data can be encrypted and transmitted with the one-time pad is limited. So there is a room for improvement for large-scale data transmission with the one-time pad method. Toshiba and ToMMo newly developed a system for sequential encryption and transmission of large-scale data, thereby...
