Quantum cryptography chip designed for commercial use
Siemens IT Solutions and Services, Austrian Research Centres (ARC) and Graz University of Technology have teamed up to develop a quantum cryptography chip for commercial use.
The chip, which protects data by generating a completely random sequence of numbers from particles of light, replaces the currently used system of key distribution based on mathematical algorithms.
The prototype 0f the quantum cryptography chip is already available, and the corresponding fibre optic network for absolutely safe, chip-based data transfer will be presented in October 2008 at Siemens IT Solutions and Services in Vienna.
Quantum cryptography works with individual light particles know as photons, which are generated and coded by an optical array. The security of the data is guaranteed by laws of nature, as photons generate completely random keys. The mathematical formulae used in the past, which could be decrypted with enough time and effort, will soon be a thing of the past.
