“…As a proof of concept to illustrate the versatility of the modular approach, a simulation experiment using different ER techniques was created. Previous work 12,26 implemented and examined performance issues associated with the Cascade, LDPC, and Winnow algorithms 13 as standalone applications. Given our new design, these algorithms were implemented as modules within the framework.…”

Quantum Key Distribution (QKD) systems are a novel technology that exploits the laws of quantum mechanics to generate and distribute unconditionally secure cryptographic keys between two geographically separated parties. They are suitable for use in applications where high levels of secrecy are required, such as banking, government, and military environments. In this paper, we describe the development of a module-based QKD simulation framework that facilitates the modeling of QKD post-processing functionalities. We highlight design choices made to improve upon an initial design, which included the segmentation of functionalities associated with various phases of QKD post-processing into discrete modules implementing abstract interfaces. In addition, communication between modules was improved by implementing observers to share data, and a specific strategy for dealing with post-processing synchronization and configuration activities was designed. Collectively, these improvements resulted in a significantly enhanced analysis capability to model and study the security and performance characteristics associated with specific QKD system designs.

“…Cascade [17] is a reconciliation method that has become the de-facto standard for all QKD practical implementations. After a number of passes, permutations and cascades, the protocol finishes with low probability that errors still remain [21]. However, large communication overhead have raised methods based on error correcting codes which are more practical.…”

We introduce a new integral method for Quantum Key Distribution to perform sifting, reconciliation and amplification processes to establish a cryptographic key through the use of binary matrices called frames which are capable to increase quadratically the secret key rate. Since the eavesdropper has no control on Bob’s double matching detection events, our protocol is not vulnerable to the Intercept and Resend (IR) attack nor the Photon Number Splitting (PNS) attack. The method can be implemented with the usual optical Bennett–Brassard ( B B 84 ) equipment allowing strong pulses in the quantum regime.

Abstract:U radu je prikazan informaciono teoretski pristup razmeni kriptografskih ključeva, odnosno informaciono teoretski protokol za distribuciju kriptoloških ključeva, koji je baziran na satelitskom scenariju. Opisane su tri faze protokola za distribuciju kriptoloških ključeva: destilacija prednosti, usaglašavanje informacija i pojačavanje privatnosti. Razvijen je simulator protokola za distribuciju kriptoloških ključeva putem javnih komunikacionih kanala. U prvoj fazi destilacije prednosti implementirani su repetitivni protokol, iterativni protokol i bit-pair iterativni protokol. Za drugu fazu korišćen je kaskadni protokol, a u trećoj fazi primenjena je univerzalna klasa hash funkcije Н1. UVODU ovom radu razmatramo dogovor tajnog ključa (secret key agreement, engl.) koji je zasnovan na informaciono teoretskoj sigurnosti. Dogovor tajnog ključa je jedan od najbitnijih faktora u kriptologiji i ima zadatak da reši problem generisanja ključeva i njihove distribucije između korisnika. Tradicionalni načini distribucije kriptološ-kih ključeva koriste kriptosisteme sa javnim ključevima koji se zasnivaju na teško izračunljivom problemu kao što je faktorizacija velikih brojeva ili korišćenje diskretnih logaritama, iz čega sledi da su oni samo računski bezbedni. Sa druge strane, razvojem računarskih tehnika, kao što su kvantni računari, u budućnosti se može smanjiti nivo njihove kriptografske sigurnosti.Rad je organizovan na sledeći način: opisan je model informaciono teoretskog dogovora tajnog ključa, zatim je dat opis praktičnog scenarija za dogovor tajnog ključa (satelitski scenario). Obrađene su sve faze protokola za distribuciju kriptoloških ključeva koje uključuju: destilaciju prednosti, usaglašavanje informacija i pojačavanje privatnosti. Za potrebe ovog rada je izrađen simulator protokola za distribuciju kriptoloških ključeva preko javnih komunikacionih kanala. Za prvu fazu destilacije prednosti je implementiran: repetitivni protokol, iterativni protokol i bit-pair iterativni protokol, za drugu fazu kaskadni protokol, a za treću fazu univerzalna klasa heš funkcije Н1. DISTRIBUCIJA KRIPTOLOŠKIH KLJUČEVA KAO GLAVNI PROBLEM U KRIPTOGRAFIJIUpravljanje kriptološkim ključevima podrazumeva: sigurno generisanje, distribuciju i čuvanje ključeva. Sigurnosna metoda upravljanja ključevima je od ekstremnog značaja za celokupan bezbednosni sistem. U kriptološkoj infrastrukturi veliki broj napada nastaje na nivou upravljanja ključevima, dok se napadi na algoritme dešavaju vrlo retko. Učesnici u kriptografskim sistemima moraju biti sposobni da generišu ključeve, odnosno moraju biti dostupni korisnicima u komunikaciji. U slučaju da dođe do kompromitacije ili gubitka ključa od strane učesnika X, ostali učesnici u komunikaciji moraju biti upozoreni na vreme. U suprotnom će napadač moći da ukradenim ključem dešifruje poruke koje su tim ključem šifrovane. Takođe, korisnicima mora biti omogućeno da na siguran način čuvaju ključeve i učine ih dostupnim isključivo za legitimnu upotrebu. Održavanje integriteta speci kacija.Obzirom da k...
