Technology tends to leave no depths of realms unplumbed or given to chance. Quantum computing was merely such a theoretical plausibility that is today a looming possibility and a menace to the survival of traditional computing. Though distant from acceptable maturity, quantum computing is an actuality, an assurance, and an inspiring inevitability. It is not simply an augmentation of the current methodology but an entirely avant-garde approach to calculations and computing.
The traditional approach provides a literal binary approach to the functions of a computer. Any single computing bit is allowed to exist in either 0 or 1 positions. The integration of quantum state of elements into computing has rendered a qubit disposition possible. Thus, infinite states of existence occurring between 0 and 1 can be now exhibited by the conventionally restricted computing values.
Every new incorporation into the field of technology has to be treated with respect in regard to the new challenges it poses as well. Quantum computing provides us with the ability to acknowledge the more comminuted factors of computing, and the security issues that come with it is equally strenuous and demanding.
Presently, the major aspects covered under cybersecurity with binary denominations are Application Security, Information Security, Disaster Recovery, and Network Security. The definitions for each of these are simply literal translation and expansion of the topic headings itself. However, the introduction of quantum computers into the vista brings with it, a requirement of much more sophisticated measures. This is due to the fact that quantum computing is much more powerful and the problems that traditional computers might take years to resolve can be done in a matter of hours by their quantum counterparts. This, in turn, means that the moment a quantum computer is connected and booted up, encrypted data across the internet is openly available.
The online science colleges as well as traditional universities understand this issue and the risk related with it and have begun providing courses and academic resources related to the resolution of such issues so that students, from a young age, can modify their thinking and come up with innovation in this field.
This projects to the inevitability of the distribution functions that are brought along using the quantum effects, offering us a compelling methodology for sharing cryptographic access between remote parties with inferred security. IBM has responded to this rising issue by promoting the employment of quantum-feasible cryptography which capitalizes on minimum quantum effects.
The present versions of encryption encompass the symmetric-key cryptography and the asymmetric-key algorithm, the latter being favored and exploited more. Recent theories and subsequent research have brought in 3 major alterations that quantum computing would bring to cybersecurity.
The president of security research at Trend Micro, Rik Ferguson is of the opinion that the introduction of a quantum angle to computing is game-changing since traditional encryptions rely on the fact that factorization of numerically large prime denominations is really hard and time-consuming hence, the data is safe.
However, this kind of factorization is an easy task for quantum computers reducing resolving time from many years to just a few minutes or hours. This proves a risk when in the wrong hands. Hackers and crackers can employ the same advantage to disarm traditional encryptions and render the users’ data vulnerable. The momentum is always greater than the traditional methods but the ethics are not always controllable.
Authority and Influence
The Shor’s algorithm used by quantum computers poses a challenge to the current cryptography. The ‘brute-force’ attacks executed by quantum computers are enough to disarm any currently known unbreakable algorithms. However, according to the senior threat analyst at FireEye, Parnian Najafi, such quantum computing measures will not be affordable to cybercriminals. Thus, the only real threat to privacy will be rogue nations and government agencies.
Security and Protection
Like any technological advancements, it is important to work against the misuse of quantum computing power. This has to be done while working on its development and not after the first threat has been discovered. Prevention is always better than cure. Security specialists are presently accumulating, modifying and deploying quantum-resistant conclusions that could revolutionize cryptography.
Key distribution methods such as Quantum Key Distribution (QKD) is a mode that employs entanglement of the quantum realm to dispatch information and data in quantum states that would be the quantum equivalent of our current encryption strategies. Quantum Key Distribution is based wholly on the indeterminacy of the quantum state. This states that any measurement attempts on the data will affect its original state thus notifying the users at the encoding and decoding end of any hacking activities pertaining to their data allowing them to change keys and encrypting it in a different manner immediately.
In addition to QKD, IBM researchers are working on a modified encryption tactic employing mathematical lattices in which the message or data is concealed under complicated algebraic structures.
A ‘quantum vs quantum’ era will prove to be the most practical and feasible approach to these issues. The current model of cryptography and encryption methodology will be rendered insufficient for the future as the digital overlords with a quantum face take over the world. Subjects pertaining to cybersecurity that are taught at advanced universities like the Capella University should take into consideration the dissemination of data related to quantum security that are incorporated with Heisenberg’s Uncertainty Principle and observations by Stephen Wiesner. Concerted works related to the research by IBM, Thomas. J. Watson Research Center, and the University of Montreal has also proposed various secure communication channels.
