Abstract: GRID communications currently include applications that are intelligence sensitive (genetics, space, industrial intellectual property, etc). Current security of said information is based on public (asymmetric) key algorithms – hash funtion algorithms that are easy calculable directly and impossible (un-proven) in reverse. The base assumption is that of the difficulty of factorising prime numbers, which received a serious blow in 1994 (Peter Shor), when it was shown that a quantum computer can factorise rapidly prime numbers via a polynomial algorithm. Such message, intercepted today and stored until quantum processors become available, can be deciphered. Evidently, data with 2-5 year “life span” are perfectly safe today, however censi , geological data, etc need to be adequately protected. Quantum crypted communications eliminate the possibility that in the future (with the onset of quantum processors) they may be deciphered. In crypting theory it was shown (G. Vernam, AT&T - 1926) that the use of a hash function with a key of equal length (or greater) than the message can guarantee the safety of the communication. The problem of the (symmetrical) key protocol is however the exhaustion of the hash tables (the functions are implemented as tables using random numbers delivered by natural sources - for instance alpha decays). After exhausting the tables, the communication partners need to re-establish contact and exchange a new set of tables. This has come to be known as the Key Distribution Problem. Quantum Key Distribution (QKD) is secured by the very essence of the quntum nature: any quantum state measured in any way collapses into one of its projections. It cannot be re-generated to its initial state, thus being impossible to clone and be kept a copy thereof. Therefore the distribution of quantum public key is similar to the Vernam cipher (symmetrical – with secret key). This type of communications has not been tested previously in Romania, although such tests have been performed internationally, in the US, France, Germany, and by the major swiss banks in Geneva. The project here standing aims to apply this technology to GRID communications through optical fiber, by: - realising the equipment necessay and - testing it on 2 GRID-computing clusters This approach will allow to optimise the quantum security technology from two points of view: - IT: communication speed, data volume / key, as well as - PHYSICALLY: bit error rate, immunity to jamming as well as to experiment one’s own Privacy Amplification, Key Distillation algorithms and determine the optimum data-volume/security for this new type of communications. It is also envisioned to accumulate expertise in operating such type of communications by simulating attacks on the system, to determine its vulnerability to: - attacks with intense laser pulse to jam the receiver - attacks with intense laser pulse to track the pulse through the transmitter’s chain and directy detect (passage thorugh the phase modulator) the transmitted bits Expertise obtained thereby will be disseminated nationally by attracting interested bodies in this type of communications: Parliament, Executive, bank system, national security agencies (SRI, STS, SPP, SIE). It is envisioned to evaluate the opportunity that the accumulated expertise and algorithms be pattented.
