Information security can provide confidentiality, integrity, and availability for society to benefit efficiently from data storage and open networks. Free space communication networks suffer from adversaries who interfere with data on networked computers. Inventing new protection techniques has arisen to ensure integrity and authenticity of digital information. This chapter introduces Nano and Bio techniques in cryptography to enhance the information security systems. Tasks unfeasible on a classical computer can now be performed by quantum computers, yielding a big impact on online security. Threats of exponentially fast quantum algorithms on business transactions could be overcome by this new technology. Based on biological observations, the exploration of biometric cryptography and authentication to determine individuals' authenticity can be done through numeric measurements.

Obfuscation Technique

With the fast development of digital exchange of data in an electronic way, data and information security are becoming more important in both transmission and data storage. Cryptography is used as a solution which plays an important role in data and information security systems against malicious attacks. The encryption technique is used to provide confidentiality to the data during transmission because security threats are more on data during transmission than data at rest. One can also use encryption to secure user’s data at data storage (i.e., data at rest). But an encryption algorithm consumes a more amount of computing resources such as processing power, memory and computation time. Obfuscation technique is a very lightweight technique that comes into a picture to protect the data at storage from malicious attacks. There are many obfuscation techniques are available to ensure the confidentiality of the data. In this paper, an obfuscation technique has been proposed and implemented which uses a 128-bit key to improve the security of the data. The experimental results show that the time taken for obfuscation and de-obfuscation is less and also from the security point of view it provides high avalanche effect

Secure Environment

Library is a trinity of documents, patrons, and staff. The goal of library security systems is to offer a safe and secure environment to this trinity. There are both natural and man-made threats. Trained guards, locks, alarms, turnstiles, safes, security lighting, duress alarms, closed circuit televisions, and RFID are a few well-known security measures. RFID, the latest development, is being used in many libraries. Though some studies state RFID has health hazards, it has a lot of advantages making it popular. Modern library is also a storehouse of digital information and therefore digitized information, too, has to be secured. Information security programmes are also addressed in this chapter.

Pros And Cons

The multi-pattern matching is a fundamental technique found in applications like a network intrusion detection system, anti-virus, anti-worms and other signature- based information security tools. Due to rising traffic rates, increasing number and sophistication of attacks and the collapse of Moore’s law, traditional software solutions can no longer keep up. Therefore, hardware approaches are frequently being used by developers to accelerate pattern matching. Reconfigurable FPGA-based devices, providing the flexibility of software and the near-ASIC performance, have become increasingly popular for this purpose. Hence, increasing the efficiency of reconfigurable information security tools is a scientific issue now. Many different approaches to constructing hardware matching circuits on FPGAs are known. The most widely used of them are based on discrete comparators, hash-functions and finite automata. Each approach possesses its own pros and cons. None of them still became the leading one. In this paper, a method to combine several different approaches to enforce their advantages has been developed. An analytical technique to quickly advance estimate the resource costs of each matching scheme without need to compile FPGA project has been proposed. It allows to apply optimization procedures to near-optimally split the set of pattern between different approaches in acceptable time.

Digital File

Current data storage technologies cannot keep pace longer with exponentially growing amounts of data through the extensive use of social networking photos and media, etc. The "digital world” with 4.4 zettabytes in 2013 has predicted it to reach 44 zettabytes by 2020. From the past 30 years, scientists and researchers have been trying to develop a robust way of storing data on a medium which is dense and ever-lasting and found DNA as the most promising storage medium. Unlike existing storage devices, DNA requires no maintenance, except the need to store at a cool and dark place. DNA has a small size with high density; just 1 gram of dry DNA can store about 455 exabytes of data. DNA stores the informations using four bases, viz., A, T, G, and C, while CDs, hard disks and other devices stores the information using 0’s and 1’s on the spiral tracks. In the DNA based storage, after binarization of digital file into the binary codes, encoding and decoding are important steps in DNA based storage system. Once the digital file is encoded, the next step is to synthesize arbitrary single-strand DNA sequences and that can be stored in the deep freeze until use.When there is a need for information to be recovered, it can be done using DNA sequencing. New generation sequencing (NGS) capable of producing sequences with very high throughput at a much lower cost about less than 0.1 USD for one MB of data than the first sequencing technologies. Post-sequencing processing includes alignment of all reads using multiple sequence alignment (MSA) algorithms to obtain different consensus sequences. The consensus sequence is decoded as the reversal of the encoding process. Most prior DNA data storage efforts sequenced and decoded the entire amount of stored digital information with no random access, but nowadays it has become possible to extract selective files (e.g., retrieving only required image from a collection) from a DNA pool using PCR-based random access. Various scientists successfully stored up to 110 zettabytes data in one gram of DNA. In the future, with an efficient encoding, error corrections, cheaper DNA synthesis,and sequencing, DNA based storage will become a practical solution for storage of exponentially growing digital data.

The Impact

The main idea of this research is to examine how teleworking has affected employee perceptions of organizational efficiency and cybersecurity before and during the COVID-19 pandemic. The research is based on an analytical and empirical approach. The starting point of the research is a critical and comprehensive analysis of the relevant literature regarding the efficiency of organizations due to teleworking, digital information security, and cyber risk management. The quantitative approach is based on designing a structural equation model (SEM) on a sample of 1101 respondents from the category of employees in Montenegro. Within the model, we examine simultaneously the impact of their perceptions on the risks of teleworking, changes in cyber-attacks during teleworking, organizations’ capacity to respond to cyber-attacks, key challenges in achieving an adequate response to cyber-attacks, as well as perceptions of key challenges related to cybersecurity. The empirical aspects of our study involve constructing latent variables that correspond to different elements of employee perception; namely, their perception of organizational efficiency and the extent to which the digital information security of their organizations has been threatened during teleworking during the pandemic.
