Information security is a key challenge in today’s information era where a huge volume of data is being generated on the internet as a result of the online transaction. This data needs to be protected from the unauthorized users on the web. Cryptography is used to ensure the confidentiality and integrity of data in the virtual world. The strength of the cryptographic algorithm relies on the complexity involved in retrieving the original content from the unintelligible information. The system proposed in this paper focuses on the use of a different mechanism to increase complexity involved in the cryptanalysis. Different cryptographic techniques are used to create a modified plain text and modified key. The newly generated key is used to encrypt the modified plaintext to generate the ciphertext. From the security analysis, it is evident that the time taken for cryptanalysis by the proposed scheme is more when compared with the existing systems.  

In the era of a global village, a huge amount of people are connected to the web through their PC, mobile and any type of communication tool for communication purposes, hence we require a safe approach that provides security and protection from unauthorized clients and misuses of data and information. Cryptography is a widespread technique to guarantee security for the internet-based communication framework. Many cipher technique have developed but the rail Fence is the simplest and amusing cryptographic algorithm until now. In this technique, the plain text is organized as crosswise and read it from top to the bottom row produces the cipher text. An inadequate quantity of keys is its weakness. This paper redesigned the current rail fence by applying the three basic phases: substitution phase once and transposition phases uses twice. The proposed technique ensures that the resultant cipher text is a fusion of various symbols precise by a chart. The proposed algorithm eliminates the limitation of the existing algorithm and significantly improves the performance by transforming the plain text unrecognizable and unpredictable.

The general population increasingly uses digital services, meaning services which are delivered over the internet or an electronic network, and events such as pandemics have accelerated the need of using new digital services. Governments have also increased their number of digital services, however, these digital services still lack of sufficient information security, particularly integrity. Blockchain uses cryptographic techniques that allow decentralization and increase the integrity of the information it handles, but it still has disadvantages in terms of efficiency, making it incapable of implementing some digital services where a high rate of transactions are required. In order to increase its efficient, a multi-layer proposal based on blockchain is presented. It has four layers, where each layer specializes in a different type of information and uses properties of public blockchain and private blockchain. An statistical analysis is performed and the proposal is modeled showing that it maintains and even increases the integrity of the information while preserving the efficiency of transactions. Besides, the proposal can be flexible and adapt to different types of digital services. It also considers that voluntary nodes participate in the decentralization of information making it more secure, verifiable, transparent and reliable.

Internet of things technology is developing at an exceptionally fast pace. This applies to both industrial and consumer Internet. The "things" account for billions, and many areas of application have been formed. At the same time, the state of information security of the Internet of things is not satisfactory, and protective measures are clearly inferior to Commerce. This is especially dangerous because the Internet of things spans two worlds: digital and physical, and security breaches can cause both informational and physical damage. The Internet of things is developing rapidly, so it is natural that it experiences typical growth diseases-fragmentation and uneven development. The base for ensuring security is mostly formed (but continues to be formed), the question is how quickly there will be a harmonization of approaches, and advanced ideas will be accepted by device manufacturers. Many state and non-state agencies actively promote security tools, inform and train manufacturers and consumers. The article is an overview of the main provisions of information security of the Internet of things. An attempt is made to consider software and technical and legislative levels of Internet of things security. This makes it different from other publications of a similar nature. Only a holistic, integrated approach can improve real information security. Authors outline basic concepts and describe a reference model of Internet of things, draw attention to the peculiarities of the Internet of things that are important from the security point of view, enumerate typical threats for Internet of things. The legislative level of information security, security recommendations for the Internet of things, manufacturers description of usage, and installation of software corrections are considered in detail.

Cryptography is an old idea and science, but its approach exists and plays a large role in modernization today. Conventional cryptographic techniques form the basis of today's cryptographic algorithm. The different categories of algorithms have their respective features; internally, in performance and implementation. Cryptographic schemes and mechanisms have undergone continuous improvement. The application of cryptography has grown increasingly, ranging from limited use in state institutions to widespread use by private individuals and companies. The increased use of the Internet has significantly influenced the nature of applications and the way we communicate. Data security dictates the use of different cryptographic techniques. For this reason, we analyze in detail the various coding techniques by evaluating their performance and efficiency. Regarding the new paradigms in cryptography there are also new cryptographic schemes whose application requires detailed study and analysis. The classical cryptography algorithm is the oldest algorithm that was used long before the cryptographic system was discovered. Currently, the system has been widely applied to secure data, and using new methods in a way to improve existing methods. In this thesis the use of cryptographic methods using the C # programming language will be discussed.

The password system is the most conventional method among validation techniques on the internet and is operated more easily and effectively than other methods. However, it is a vulnerable method against attacks such as eavesdropping or replay attack. To prevail over this problem, OTP (One Time Password) technique is used. The most popular OTP is HOTP algorithm, which is based on one-way hash function SHA-1. The recent researches show the weakness of the hash function. So, in this paper we created a module which uses another cryptographic algorithm. Cryptography in the current world serves an important role in data security. Cryptography means writing of secret codes (cipher text) which is in an unintelligible form and cannot be read unless we have a perfect key to decode it. The proposed method is AES algorithm (128 bit) followed by Middle Square method to generate an OTP. As OTP is a 4-6 bit number we will decrease the AES output to a 4-6 bit through Middle Square method and this OTP can be used as a security tool in many cases like online transaction purposes.

Abstract: Data is any type of stored digital information. Security is about the protection of assets. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers, personal databases and websites. Cryptography is evergreen and developments. Cryptography protects users by providing functionality for the encryption of data and authentication of other users. Compression is the process of reducing the number of bits or bytes needed to represent a given set of data. It allows saving more data. Cryptography is a popular ways of sending vital information in a secret way. There are many cryptographic techniques available and among them AES is one of the most powerful techniques. The scenario of present day of information security system includes confidentiality, authenticity, integrity, nonrepudiation. The security of communication is a crucial issue on World Wide Web. It is about confidentiality, integrity, authentication during access or editing of confidential internal documents. Keywords: Cryptography, Hill Cipher, Homophonic Substitution Cipher, Monoalphabetic Cipher, Ceaser Cipher.


The internet of things is turning into an appealing framework worldview to acknowledge inter-connections throughout corporeal, digital as well as communal gaps. Through the connections amid the IoT, safety concerns befall important, along with it is huge to set up improved resolutions for safety protections. The IoT apparition of unlock data sharing is expert through using cloud registering concepts.

Information data security is an important aspect of exchanging data and information. Data and information security can be done in various ways, including by using the cesarean cipher method in cryptographic techniques. The cesarean cipher method of cryptographic technique is a substitution coding system which is done by replacing each alphabet character with other characters along the 26 alphabet characters so that the coding only occurs in the alphabet itself without any other punctuation. This study proposes a modification to the cesarean cipher technique by adding to the number of characters used, namely 256 characters in the ASCII code. The caesar cipher application or CaesarApp uses the methodology of library study, consultation, application design and application testing. The implementation of the CaesarApp application was created using the open-source Android Studio 3.5 application. The results of tests conducted on the CaesarApp application note that the modification of the caesar cipher with 256 ASCII characters results in a secure information data security application, this application has a deficiency in reading limitations on ASCII characters, so characters cannot be read properly on android users.

Following years of discussion surrounding the characteristics, both positive and negative, of generations X and Y, we are seeing the emergence of what is referred to as the virtual generation, the net generation, or Generation V. To some, the virtual generation includes 15 to 24 year olds who spend significant amounts of time playing video games, browsing the Web, and communicating over the Internet (Proserpio & Gioia, 2007). Tapscott (2009) defines the net generation as the first generation to have grown up in the digital age. To others, Generation V is a generation that transcends age, gender, social demographic, and geography, and encompasses everyone who participates in a virtual environment (Sarner, 2008). Regardless of the exact parameters of the generation in use, as the virtual generation enters our academic institutions en masse, we need to ensure that we are providing educational environments that encompass the technological world in which they live, that defines who they are. Rather than requiring them to be confined solely to traditional lecture-based pedagogy, let the virtual generation learn in a virtual world.
