Cryptography systems using the laws of quantum mechanics to produce hack-proof networks are becoming available. The Vectis Link Encryptor system produced by id Quantique SA of Geneva, Switzerland, supports quantum encryption between two Fast Ethernet networks as far apart as 100 kilometers (62 miles). Conventional network security has depended on key length as much as 256 bits long; however, a supercomputer can discover such keys by trial and error. Quantum cryptography is secure because different quantum states of individual photons represent ones and zeroes across a specific probability distribution. A hacker contacting an encrypted photon would change that distribution, simultaneously rendering the key unavailable and alerting the receiver the key had been observed. Vectis combines uncompromised security with easy integration into existing networks. Research and development companies, service providers, government agencies, and financial services are among potential customers for such a system. Encryption and decryption overhead creates sub-millisecond latency, a standard compatible with communications such as voice over IP. The Vectis unit has a user-friendly touchpanel display for tamper-detection results and provides pushbutton access to the Simple Network Management Protocol.
