Toshiba is working on an Internet-based communication encryption system, which industry analysts say will be unbreakable, The Wall Street Journal reported Monday (June 22). Engineers believe one of the best ways to ensure communication stays secret is to create a one-time key to decide the encrypted data, but difficulty in finding ways to transfer this key without risk of interception remains a challenge. Toshiba’s system bypasses this risk by providing a foolproof method of distributing secret digital keys through a custom-made fiber optic cable that is not connected to the Internet. In a company release, Toshiba explained: “Quantum cryptographic communication uses quantum physics to ensure that genomic data encrypted with digital keys remains secret. Standard optical communications can be intercepted and read by measuring a part of the optical signal. However, in quantum communications, bits are carried and sent by individual photons, which cannot be tampered with without leaving a trace of the intrusion. As a consequence the secrecy of untampered encryption keys, and the genome data they protect, can be guaranteed.” Verification testing will begin on Aug. 31, marking the first time a quantum cryptographic communication system will be used to test actual data in Japan. “In a two-year verification […]
