Technology Overview
Increasing Need for Tighter Data Security to Drive Quantum Cryptography
Currently, communication systems are secured largely by means of algorithm-based encryption, while the distribution of the algorithm keys is done by another set of algorithms – a method that has many flaws in terms of data security. In addition, conventional data communication systems are under the threat of unpredictable advancements in factorization algorithms and the development of quantum computers. 'These developments increase the threat of hacking and could have serious repercussions for activities that demand secrecy of information such as military and government operations,' according to the analyst of the study. 'In addition, the next-generation quantum computers, may be designed to use the laws of quantum mechanics to carry out computational tasks.'
The realization of this concept can threaten the security of existing networks, which rely on classical encryption techniques. This could be attributed to the fact that quantum computers are expected to perform computing operations at exponentially faster speeds, which facilitates the cracking of the algorithms code in a matter of few seconds.
Focus on Secure Public Key Algorithms to Drive Demand for Quantum Cryptography
Currently, data security is provided by classical cryptographic systems utilizing public key algorithms. The realization of such fast factorization algorithms would make such public key algorithms vulnerable to security-related attacks. This infers that as long as integer factorization remains difficult to perform, these public key algorithms would remain secure. The technology that comes to the rescue of such threats related to data security is quantum cryptography (QC) and quantum key distribution.
QC systems circumvent all major disadvantages of classical cryptography, as they do not depend on computational theory for security. On the contrary, QC is an approach that is governed by the laws of quantum physics. 'The main goal of QC is to provide a safe real time network system that enables corresponding detection of unauthorized intruders,' says the analyst. 'Moreover, QC technology has the ability to provide security at the highest level for applications across industries such as financial institutes, military, banking, government, and other sectors.'
