Unbreakable Crypto: Who Needs It?
Startup MagiQ Technologies is working on a device that uses quantum cryptography to encode keys on existing high-speed networks, but cryptographers say system holds little value for enterprises.A New York-based startup on Monday announced that it has a working prototype of a device capable of employing quantum cryptography to encode keys on existing high-speed networks. However, cryptographers say the system likely holds little value for enterprises. MagiQ Technologies Inc. is among the first companies to announce its intention to sell a commercial solution based on the concept of quantum cryptography. Code-named Navajo, the system comprises an appliance at either end of the communications link, capable of generating keys and encoding them one photon at a time. Quantum cryptography relies on the properties of photons and the laws of quantum mechanics, which dictate that an eavesdropper wouldnt be able to read or even observe a photon without changing its state. That would alert the receiver that the message had been intercepted and was no longer secure.
Because of these properties, quantum cryptography long has been considered the Holy Grail of cryptography. There has been quite a bit of hype and misinformation surrounding research in this field, and the companies that attempt to commercialize the technology will face a lot of scrutiny from both security experts and crackers. MagiQ officials acknowledge this and say theyre taking all due caution to ensure that they dont make any mistakes.
