The trial between Toshiba Corporation and ToMMo was intended to solve for the following two problems.
First, genomic data (genome and DNA data) under certain conditions is legally treated as personal information identifying specific individuals and comprises approximately 3.2 billion bases. High-precision analysis using the latest sequencers obtains more than 90 billion bases, nearly thirty times that number.
Second, at the time of the trial, the key distribution speed with quantum cryptographic communication technologies was at a maximum of around 10 Mbps, so the speed at which data could be encrypted and transmitted with the one-time pad was limited.
During a two year period from August 2015 until August 2017. Toshiba Life Science Analysis Center genome data produced with the “Japonica Array™*1” Japanese genome analysis tool was encrypted with a Toshiba QKD system and transmitted to ToMMo, over a distance of 7 km.
The testing monitored and verified communication stability speed in long-term operation and the impact of environmental conditions, including weather, temperature and the status of the optical connection.
