Abstract

Have you ever tried to retrieve that forgotten key code for your suitcase? After one year without traveling, many of us found themselves having forgotten the combination and manually trying all permutations. The same situation, but more complex, would be to systematically try identifying that forgotten access code for an online app that you had not used for a while. Cyberattackers are doing exactly this, of course, at high speed and with increasing computing performance. The recommended security key length is thus getting longer by the year. Yet, the stepwise process to achieve this is tedious or consumes lots of computing power. Now imagine that all of these possible states could be tried in a single step. This would be good for your own number lock, but frightening for our security infrastructure.

Self-Healing Post Quantum Cryptography

Neelakantappa B B Neelakantappa B B

Computers are getting way faster.Right now, people are making a brand-new kind of machine.It is called a quantum computer.This sounds like a good thing, but it actually creates a huge problem for our everyday internet safety.The normal security codes we use today to guard our internet data cannot stop these new machines.Quantum computers will easily break the locks that protect our online banking apps, files on cloud servers, private hospital details, and everyday smart home gadgets.To fix this big problem before it causes real damage, our project brings in a new kind of digital shield.We call it a Self Healing Post-Quantum Cryptography framework.This system works by mixing ultra-strong security codes that are too hard for a quantum computer to solve with round-theclock network watchdogs.The best part of our design is that it can heal itself.The system never goes to sleep.It sits in the background and constantly watches the data traffic moving along the network lines.If an outside hacker tries to sneak past the gates, or if a secret security key accidentally leaks out or gets stolen, the system fixes the issue right away.It immediately throws away the ruined, broken keys.Then, it sets up brand-new quantum-proof codes and patches the broken communication paths back together.It handles the entire repair job all by itself in a split second.Because of this, users do not have to sit around waiting for a human IT worker to log in and manually fix the glitch.Our real-world tests prove that this smart setup keeps private information safe, stops messy network crashes, and cuts down unexpected system downtime during live cyber-attacks.Tests show that this approach keeps information safe, keeps networks online, and cuts down system downtime during cyberattacks.

Security enhancement of 2-D DIM codes using 4 × 1 NOR logic based on FISO

Simarpreet Kaur, Simranjit Singh

Abstract Security enhancement and bandwidth increase are requirements of ultrafast future optical code division networks that also minimise the latency at nodes without distressing the traffic performance. In OCDMA systems, eavesdropper tries to breach the optical code, and encoded/encrypted data in order to get correct code word of legitimate user. For security enhancement, an ultra high speed 4×100 Gbps two dimensional Diagonal identity matrix (2D-DIM) code and four input single output (FISO) all optical logic gate (AOLG) with private key encryption is proposed and its performance in terms of security is analyzed. Expressions for synchronous and asynchronous transmissions are derived for proposed work and it is perceived that asynchronous transmission has better security. Further performance/security analysis is carried out for different scenarios such as with/without FISO, with 1D-DIM/2D-DIM codes, using 4×1 AND gate/NOR gate in terms of correct code detection rate (CCDR), max. eye amplitude (MEA), Received Q factor, Signal to noise ratio (SNR) at different launched power levels for legitimate user and eavesdropper. Eavesdropper attacked the proposed system but due to FISO layering, private key encryption, and 2D-DIM codes, cannot get acceptable level of CCDR. To the best of author’s knowledge, proposed system is ultra high speed with enhanced security and no reported studies have investigated security enhancement at this much ultra high speed.

A Survey on Quantum Computing for Recommendation Systems

Giovanni Pilato, Filippo Vella

Recommendation systems play a key role in everyday life; they are used to suggest items that are selected among many candidates that usually belong to huge datasets. The recommendations require a good performance both in terms of speed and the effectiveness of the provided suggestions. At the same time, one of the most challenging approaches in computer science is quantum computing. This computational paradigm can provide significant acceleration for resource-demanding and time-consuming algorithms. It has become very popular in recent years, thanks to the different tools available to the scientific and technical communities. Since performance has great relevance in recommendation systems, many researchers in the scientific community have recently proposed different improvements that exploit quantum approaches to provide better performance in recommendation systems. This paper gives an overview of the current state of the art in the literature, outlining the different proposed methodologies and techniques and highlighting the challenges that arise from this new approach to the recommendation systems domain.
